The Buyer’s Guide: Blue Diamonds
Blue diamonds are considered extremely rare when it comes to grading and investing in Natural Fancy Color Diamonds. Given this rarity, it is no wonder that collectors around the world seem to snap them up whenever a new blue diamond is discovered or surfaces from a private collection.
From ice and steel to ocean and sky, blue diamonds come in a range of shades that denote power, prestige and elegance.
High-end investors in particular enjoy the beauty and revenue that Natural Fancy Blue Diamonds provide due to their great scarcity in the market. This rarity brings high prices, which is evident on the auction block with record prices for blue diamonds continuing to soar in the multimillion-dollar regions. This translates to the supply chain, where more modest collectors are spending significant capital on blue diamonds for hundreds of thousands of dollars.
At Guildhall Diamonds Inc., we continue to experience ongoing price increases in the industry while also realizing diamond values on the rise with diamond reappraisals.
Origin: Natural Fancy Blue Diamonds
Blue diamonds can get their color from nitrogen and/or hydrogen and/or boron trace elements within the structure of the diamond. Boron atoms produce the blue color in the majority of blue diamonds as they create increased light absorption in the diamond from blue to yellow to red, providing the most magnificent of array of blue hues.
Blue diamond discoveries have been made in various parts of the globe, including Indonesia, India and Africa — though it is important to note that blue diamond mining is generally minuscule. Blue diamonds are mined with more consistency in South Africa and Australia but generally account for approximately less than 5% of all Natural Fancy Color Diamonds mined per year.
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.
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
When purchasing white diamonds, as opposed to Natural Fancy Color Diamonds, certain value factors such as clarity, cut or carat weight may take precedence over the color and may be the determining factor of the diamond’s value for an individual. 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. Guildhall Diamonds Inc. seeks to find Blue Diamonds in Fancy, Intense and Vivid color grades in tandem with high-clarity grades.
Blue diamonds must be evaluated on their distinct color category since they do not typically get as saturated as other color diamonds such as yellow or pink diamonds.
Finding the highest clarity possible will help ensure a long-term growth in value. It is particularly rare to find Flawless Blue Diamonds nowadays, so clients will generally find Internally Flawless (IF) and VVSI (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.
IF Internally Flawless
VVSI/2 Very, Very Slightly Included
VSI/2 Very Slightly Included
SI/2 Slightly Included
I I/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.

There is a minimum carat weight that a blue diamond must meet in order to be considered valuable.
