The Buyer’s Guide: Yellow Diamonds

Yellow diamonds may glisten like a golden ray of sunshine,
but they also make strong investments.

Yellow diamonds range from sunny shades of daffodil to lemon and gold, capturing the hearts of connoisseurs and jewelry enthusiasts alike. Investors worldwide enjoy the beauty and profit potential that Natural Fancy Yellow Diamonds provide. Although not quite as rare as some natural fancy diamonds (pink, blues, red or green), yellow diamonds, particularly in Flawless and Internally Flawless clarity grades, are becoming increasingly harder to procure and as a result, their value is increasing on a consistent basis.
Yellow diamonds also offer investors significant benefits over their red, blue, purple and orange counterparts.
At Guildhall Diamonds Inc., we continue to experience ongoing price increases on the buying end of the business and on the results of our diamonds being reappraised on a yearly basis.

Origin: Natural Fancy Yellow Diamonds

Yellow diamonds are mined in Western Australia, South Africa, India and Russia. The primary mining region for Yellow diamonds is South Africa. Ethical diamonds are of paramount concern. At Guildhall Diamonds Inc., the natural fancy color diamonds selected comply with the Kimberley Process to ensure that they are conflict-free diamonds.

The Status of Wearing Yellow Diamonds

Yellow diamonds are indeed the most popular of all color diamonds and have become a symbol of wealth, achievement and glamour. Yellow diamonds have been well publicized among the celebrity and socialite culture for the past few decades. Many celebrities have been photographed on red carpets with sizable yellow diamond jewelry. Yellow diamonds have been considered a go-to status symbol for high-profile engagements the world over.
Criteria for Natural Fancy Color Diamonds

In the 1940s, the Gemological Institute of America (GIA) developed “The Four Cs” to provide a universal system for comparing and grading diamonds. Today, the Four Cs — Color, Clarity, Cut and Carat Weight — are an internationally recognized and accepted method for describing and grading diamonds.

The Four Cs

With natural fancy color diamonds, one must take color as the primary consideration above all else. It is the color that determines the value of a natural fancy color diamond. As opposed to the purchase of a white diamond, other value factors such as clarity, cut, or carat weight may take precedence over color and be the determining factor of the diamond’s value for an individual. Guildhall Diamonds Inc. seeks to find Yellow diamonds in Fancy, Intense and Vivid color grades in tandem with high-clarity grades.

Finding the highest clarity possible will help ensure a long-term growth in value. It is particularly rare to find Flawless yellow diamonds nowadays, so clients will generally find Internally Flawless (IF) and VVS (Very Very Slightly Included) diamonds in the collection at Guildhall Diamonds Inc.

Diamond clarity is evaluated through a jewellers loupe with 10x magnification. Diamond graders look for external characteristics called blemishes and internal characteristics called inclusions, which will have a varying impact on a diamond’s structural integrity, light performance and beauty. There are 11 clarity grades that range from Flawless to Included.

F  Flawless
IF  Internally Flawless
VVS1/2  Very, Very Slightly Included
VS1/2  Very Slightly Included
S1/2  Slightly Included
I 1/2/3  Included

Cut refers to the shape of a diamond and the way in which a diamond has been fashioned. Many diamond shapes (referred to as “cuts”) can maximize color. The finish and make of a diamond brought out by cutters and polishers will express the beauty and light within the diamond. Speak to your diamond specialist about the best cuts that will bring out the most value in your selected stone.

Yellow diamonds tend to be larger than other natural fancy colors, and because they are less rare than pinks and reds, people are able to purchase a larger diamond for less money than other colors such as blues, greens or pinks. There is, however, a minimum carat weight that a yellow diamond must meet in order to be considered valuable.
