Designer Engagement Rings & Jewelry Guide

Engagement ring represents a couple’s love and lifetime commitment to each other. For months and sometimes years before the proposal, the engaging woman searches for that unique ring design that describes her taste and personality the best. Then, as the time gets closer to the proposing date, the man starts shopping for the ring with best quality and value, in the style his future bride has selected for her wedding ring. In this article, designer engagement rings and jewelry are categorized by design, and guidelines are provided to help you select and purchase the best ring, pair of earrings, necklace or bracelet for your money.       

Engagement Ring Designs  
  • Halo engagement rings, most popular in cushion, round, square and oval shapes, consist of center stone in prong or bezel setting, surrounded by a single or double halo of small round diamonds in regular or French pave setting. Two reasons for their popularity are 1) The diamond halo makes the center stone appear larger in size 2) Vintage flavor of their pave setting style.  

  • Classic diamond solitaire simple and elegant, is and always will be the iconic engagement ring design. A single large diamond mounted on a thin gold or platinum band, an excellent choice for men who are planning a surprise proposal and are not sure of their fiance’s favorite engagement ring setting style and like to maximize their spending on the center diamond’s size and quality.

  • Gemstone engagement rings, specifically diamond rings with sapphire, ruby or emerald sides or accents are a great way to take the customization process one step further and make the wedding ring more personal and meaningful as each gemstone is the birthstone for a certain month of the year. For example a sapphire engagement ring would be ideal for a woman who was born in the month of September.

  • Micro-pave engagement rings, with tiny pave diamonds are favorite of women who like petite engagement rings with intricate details. Smallness of diamonds, offers designers versatility and freedom to to twist, turn and shape the ring as they like with diamonds.     

  • Three-stone rings consist of a larger center stone, with an identical shape but smaller in size diamond on each side. Their vintage version: 3-stone halo engagement rings, the halos add  extra sparkle and enhance size appearance of the three stones.  
  • Engagement rings with side-stones are diamond rings with single or multiple rows of uniform or graduated size round, princess cut or baguette diamonds, channel or prong set on the ring’s band, usually in cathedral form, leading up to the center stone.    

  • Vintage & Antique style engagement rings are old but timeless in design. Art-deco wedding rings incorporate older cut diamonds (like cushion, asscher, emerald cuts), geometric patterns and setting types (like pave and bezel), just as in real antique diamond rings.  

  • Custom engagement rings are unique, one-of-a-kind wedding rings that are designed and manufactured based on engaging woman’s specifications. Often, because of their sentimental value, gems and metal (gold or platinum) from family heirloom jewels are incorporated into building the new ring. Marketing terminologies commonly used online such as ‘design-your-own-engagement-ring’ or ‘build-your-own-ring’, make it sound like the customer is participating in making the custom, made to order ring, but actually they just  offer the process of selecting and combining a center diamond with a prefabricated ring setting.    

Earrings Styles
  • Studs are the most classic of all diamond earrings. They are the number one jewelry gift for holidays and special occasions because of their simplicity and everyday wear ability. Round diamond stud earrings are the most popular, but princess cut stud earrings and round studs with halo in gold or platinum settings are not far behind.
  • Diamond hoop earrings, often with diamonds prong or pave set on the inside and outside of the hoops, are a women’s favorite. Popular in all sizes from small to oversized ones that make a bold statement about the fashionable woman wearing them.        

  • Drop diamond earrings in long dangling form, are playful pieces of jewelry which sparkle with slightest movement. Styles with diamond and sapphire, ruby, or emerald combination are popular due to their colorfulness and affordability.      

  • Vintage and antique design diamond earrings are often square or geometrical in shape with intricate details in their designs and craftsmanship. Couple of popular styles with antique jewelry enthusiasts are vintage stud earrings and the ones with lever back ones which sit slightly below the earlobes.       

Necklace Styles
  • Tennis necklaces with diamonds set all around the neckline are the most glamorous of all diamond necklace designs. Fitting like a choker, riviera / tennis diamond necklaces consist of uniform or graduated size diamonds often in prong setting. For women who love colorful precious gemstones, sapphire, ruby or emerald and diamond tennis necklaces are beautiful options to consider.       

  • Vintage and antique style diamond necklaces usually in geometric shapes from art-deco period, combine older cut diamonds such as kite, asscher and emerald cut with rounds. Stones are usually pave or bezel set with a fine hand mil-grain finish on gold edges. The ones in high quality, come with fine intricate details in design and outstanding workmanship.    

  • Solitaire diamond pendant necklace with a single diamond sliding on a thin gold or platinum chain, is the perfect addition to a woman’s existing diamond stud earrings and / or solitaire ring. Mostly seen with a round diamond in prong setting, some prefer the vintage look of older cut diamonds like emerald, princess or asscher cuts in bezel setting.   

Bracelet Styles
  • Tennis bracelets or more commonly known as diamond bracelets, with single or multiple lines of diamonds around the wrist, have found their place among classics in fine jewelry. Even though the round diamond tennis bracelet in prong or bezel settings is the most recognized style, baguette bracelets and the ones with combination of diamond and sapphire, ruby or emerald gemstones are also very popular.     

  • Diamond bangles, in the simple one row prong to the more extravagant wide pave, to the colorful ones with diamond and sapphire, ruby or emerald gemstones, make a strong  statement about the stylish woman wearing one. Bracelets may come and go out of fashion, but diamond and precious colored gemstone bangle bracelets have always been popular with women throughout the times.       

  • Antique design bracelets often wider with art-deco era patterns, are the most spectacular of all diamond bracelets. Utilizing round and fancy shape precious gems (diamonds sapphires, rubies, emeralds) in large and small sizes are combined, creating astounding  unique styles. Vintage bracelets are outstanding family jewels that are never resold and passed on by one generation to the next.

Ruby Gemstone, Ring & Jewelry Guide

Considered ‘King of Precious Gemstones’, gem grade rubies are the most expensive of precious colored gemstones.

Best and most desirable rubies, generally found in layers in marbles, come from Burma. Burmese rubies usually contain red fluorescence which contribute to their red color intensity and hence value. Rubies from other parts of the world, are found in volcanic rocks containing iron, which makes the ruby appear darker and less intense in color. Keep in mind value of a ruby is always measured based on its quality characteristics and not the location where it comes from.

Technical Specs
Ruby is the red variety of the mineral corundum. Chromium is the element which causes the colorless corundum become red in color. Red intensity of ruby depends on amount of its chromium content. Ruby’s chemical formula is Al2O3 , its refractive index ranges 1.762 to 1.770, birefringence range of 0.008 to 0.010, specific gravity of 4.00 (+/- 0.05) and its MOHS hardness is 9.

Just as with the other two most popular precious colored gemstones: sapphire and emerald, color is the most important factor in determining value of a ruby. Best quality rubies have a rich, vibrant  red color commonly referred to as ‘pigeon blood’. As the ruby’s color tone becomes pinkish or purplish, it’s value drops.

Untreated and Heat-treated Rubies

Almost all rubies have internal inclusions. What’s important is to buy a ruby with minimal or no inclusions visible to the naked eye, as larger inclusions affect the stone’s brilliancy and transparency.

In some instances inclusions break through the surface, appearing as fractures. This type of inclusion is not desirable as it may affect the ruby’s durability.

As with other gemstones, a rough ruby cutter’s purpose is to achieve the best color and clarity while minimizing weight loss. When shopping for a ruby, make sure its cut which refers to the stone’s symmetry, proportions and polish are good as they impact its brilliancy.        

Size / Weight
Rubies are available in a broad range of sizes. Small ones weigh as little as a fraction of a carat to large ones weighing 10s of carats. As the size and quality of the ruby increases, so does its price per carat.

Rubies are cut almost into every shape and just as with all other natural gemstones, shape of the ruby’s rough crystal determines its final shape. Most common shapes for small size rubies are: round, square and princess cut. Oval and pear shaped are the most common shapes for medium to larger size rubies. With vintage style ruby jewelry ( rings, earrings, bracelets and necklaces) so popular, cushion and emerald cut rubies have price premiums in the marketplace.

Ruby Jewelry
Historically associated with passion, wisdom and beauty, ruby is the ideal romantic jewelry gift.

Ruby rings with their distinct fiery red color, from simple ruby and diamond wedding band to vintage halo to magnificent antique style, rubies always have had their die hard fans throughout the centuries.       

Ruby earrings in simple studs with diamond accents to long dangling designs  compliment a woman’s ears, facial makeup and fancy dresses beautifully.    

Ruby necklaces from classic pear shaped pendant to extraordinary all around ruby tennis necklace, rubies demand attention like no other gem can.  


Ruby bracelets, whether as an alternating ruby and diamond tennis bracelet, a ruby bangle or a spectacular antique style one, ruby bracelets are the ultimate statement makers in precious colored gemstone jewelry.     

How to Select & Buy
Use below guidelines to select and buy the best ruby gemstone and jewelry for your money.  

  • Color is the most important factor for quality of a ruby. Compare two or more rubies in the size and shape you are considering to purchase side by side as it makes differentiating between the color tones easier. Avoid purplish and pinkish color rubies as the ideal color is pure red.      

  • Even though inclusion-free rubies practically do not exist, you should select a ruby with no major inclusions visible to the naked eye, nor any that break through the surface, appearing like a crack in the stone.

  • Symmetry and proportions must be good as the ruby’s brilliancy depends on them. Do not buy shallow cut rubies with large table, nor deep cuts with heavy bottom (belly underneath).

  • When buying a ruby ring, pair of earrings, a necklace or bracelet, consider A) It’s beauty and uniqueness in design B) It’s workmanship quality C) Quality of rubies and other gems used in manufacturing D) It’s wearability and comfort E) It’s product warranty.    

  • Shop with reputable, expert jewelers and jewelry designers who offer only quality jewels, great value and outstanding customer service every time .

Emerald Gemstone, Ring & Jewelry Guide

Emerald is the green variety and the most famous member of the beryl mineral family, with its name coming from the old Greek word “smaragdus” which means green. There are other green color gemstones such as peridot and tourmaline, but emerald has always been the most desirable and precious of all.

Brief History
Known emerald mines date back to over 300 years BC in Egypt, where it was the royalty’s favorite colored gemstone for generations.

A gem associated with many ancient beliefs and myths, people believed it has psychic powers and able to foresee the future when placed in mouth and held under the tongue. Other beliefs included ability to protect against evil spell, reveal the truth or lie, improve talking skills and cure deadly diseases.

Emerald is the birthstone for the month of May and the gemstone representing the 20th and 35th wedding anniversaries.

Technical Specs
Emerald’s color is vibrant green, its chemical formula is Be3Al2Si6O18, its Refractive Index ranges 1.577 - 1.583, Birefringence range of 0.005 - 0.009, Specific Gravity of 2.72 and its MOHS Hardness varies between 7.5 - 8.

Elements that affect emerald’s color are chromium, vanadium, and iron. Their presence or lack of and their amounts determine the color of an emerald.

As for all other precious colored gemstones, color is the most important factor in emerald’s quality. The most desirable color for emeralds is vivid, rich green that’s not too dark.

Emerald’s tone of green color is generally associated with location of its mine.  Colombian emeralds have a warmer, pure green color while emeralds from Zambia mines are generally bluish green and darker / deeper in color.

When examining color, a common issue to watch out for is color zoning which refers to uneven distribution of color within the stone with some areas lighter than the rest.

To recognize the quality of an emerald’s color, it is highly recommended to compare one or more emeralds in the same shape and size range at time of purchase.

Clarity refers to presence or lack of internal inclusions. The more transparent (free of inclusions), the better is clarity grade and higher in value.  

Bluish Green Emerald

Before cutting the rough, emerald cutter must consider its depth of color, durability, and inclusions as the goal is to achieve the best color and clarity while minimizing loss in weight / size of the stone. Standards used for grading emeralds’ cut grade is not the same as for diamonds because the most important goal is to preserve and achieve the best color. Yet it is important to choose a well cut emerald with good proportions as you don’t want to pay for extra weight due to large depth.   

Carat Weight
Emeralds come in a wide range of sizes and carat weights. As small as 1/100 of a carat, all the way up to hundreds of carats.

As the emerald’s size increases, so does its price per carat, especially in higher quality  gem grade stones.

Emeralds come in variety of shapes. Most common shapes found in small sizes are round and square as they are combined with diamonds and used in manufacturing fine jewelry. Medium sizes (¼ - ½ carat) are generally used as diamond ring side stones or accents. Larger sizes (½ carat and larger) commonly seen as center stones in fine jewelry pieces are in oval, pear shaped, cushion cut and most popular of all, emerald cut.     

Emerald Jewelry
Emerald rings and bands are popular by women of all ages. Brides born in May, customize and personalize their engagement rings beautifully by incorporating emeralds in their ring’s design. Married couples buy emerald 3-stone rings to celebrate their wedding anniversaries. And being the favorite colored gemstone of royalty throughout the times, vintage emerald rings are loved by women of all ages.   

From classic studs with halo to dangling pear shaped drops to hoops, emerald earrings make extraordinary presents for women. Their beautiful lush green color and availability in all shapes and sizes, make them a favorite of natural gemstone jewelry manufacturers.      

Gem quality emeralds in emerald cut, oval and pear shaped are combined with round and fancy shape diamonds in creating some of the most luxurious necklaces in the world like the one once owned by Elizabeth Taylor. Good news is you don’t have to be super rich to afford an emerald necklace or pendant as emeralds come in all sizes and prices.

Emerald and diamond bracelets, in stiff bangle to flexible tennis to magnificent antique style with pave and bezel set diamonds, they have been a favorite of precious colored gemstone bracelet lovers throughout the times.
