Diamonds as an investment

Buying an Investment Diamond

For centuries, people have turned to diamonds as a method of wealth condensation and wealth transportation. However, in the last few decades, as the popularity of certain diamonds has significantly increased and education about their investment benefits better known, the concept of diamonds as an investment has arisen in a big way. The most notable has been the big-ticket fancy color diamonds that are sold by auction houses such as Sotheby’s and Christie’s. These diamonds time and again earn incredible prices per carat at auction, shattering previously set records and continually gaining in value and helping increase overall value for stones of those colors in the market as a whole.

One of the great benefits of privately owning an investment diamond is the control of the diamond in its entirety. That means that you alone will control when it will be resold, if at all, which allows you the freedom of passing it on as a heritage, and the security that as a universal asset worldwide, it will always be redeemable for its true value regardless of where it is ultimately resold. This fact is very appealing and a big draw for private diamond investments.

Why Diamonds?

  1. Value: It is the commodity with the highest concentration of value compared to the volume.

  2. Rarity: To open a diamond mine it takes 10y. The average yield of a mine is 1 gram every 10 tons of rock extracted and only 20% of this gram can be used in jewelry.

  3. Not volatile: Its price is not subjected to strong movements up and down, as gold.

Natural Colored Diamonds

Only one in every 10,000 diamonds possesses natural color and is referred to as a colored diamond. For this reason, colored diamonds are purchased almost exclusively for the intensity and distribution of the diamond's color. Criteria considered when purchasing a white or colorless diamond, such as cut proportions and clarity, are less important when purchasing a colored diamond. The information below will help you understand colored diamonds to determine the diamond that's right for you.

Color intensity, the deepness or richness of color, is the most important consideration when purchasing a colored diamond. The more intense the color, the rarer and more valuable the diamond will be. All of our colored diamonds possess natural color and are never exposed to artificial coloring techniques such as dyeing or irradiation.

Because the white diamond is the most widely recognized diamond color, the existence of “fancy color diamonds” may come as a surprise to some. While most mined diamonds have a yellow or brown tint, white diamonds are most commonly seen in stores because they are rarer, and thus more desirable? Outside of the normal white, yellow, and brown diamond color range, there exist a variety of fancy color diamond options such as pink diamonds, champagne diamonds, yellow diamonds, red diamonds, and chocolate diamonds.

The Gemological Institute of America’s D to Z scale is commonly used to grade the color of diamonds that fall within the normal color range, ranging from the stellar D grade of completely colorless to a Z grade of a pale yellow diamond or brown.

For diamonds, rarity equates to value. With diamonds of the normal color range, value is based on the lack of color, because colorless diamonds are the rarest. With fancy color diamonds, rarity, and thus value, increases with color intensity, purity, and rarity.

On GIA colored diamond reports, colored diamonds are graded in order of increasing color strength from Faint, Very Light, Light, Fancy Light, and Fancy to Fancy Dark, Fancy Intense, Fancy Vivid and Fancy Deep. Fancy Vivid and Fancy Deep generally command the highest prices.

  • Faint
  • Very Light
  • Light
  • Fancy Light
  • Fancy
  • Fancy Dark
  • Fancy Intense
  • Fancy Vivid
  • Fancy Deep

After color grade, carat weight has the most impact on price for colored diamonds. When diamonds are mined, large gems are discovered much less frequently than small ones. This makes large diamonds much more valuable. For this reason, diamond prices for colored diamonds rise exponentially with carat weight. 

Due to the nature of colored diamonds, clarity is less important than it is in their colorless counterparts. This is true because inclusions tend to be masked by the diamond's color.

Colored diamonds are primarily cut to emphasize their color. This contrasts with colorless diamonds that are cut to maximize sparkle or brilliance, which in some instances can detract from the natural color of a colored diamond. While colored diamonds still exhibit brilliance, color is the most important characteristic considered when they are being cut.

While cut describes a diamond's light performance, dimensions and finish; shape refers to the overall outline of the diamond when viewed from the top (e.g. round, princess or marquise). It's important to note that many colored diamonds are cut into non-traditional shapes to enhance their natural color. Due to the rarity of colored diamonds, a specific shape in a specific color may not be available at any given time.

All MIKU Diamonds colored diamonds are independently analyzed and graded by the Gemological Institute of America (GIA), which is among the most respected laboratories in the diamond industry. Each diamond is accompanied by a colored diamond identification and origin report. This authoritative report lists the diamond's specifications including its color grade, and ensures its natural origin.

At MIKU Diamonds we are committed giving you the true quality of natural diamonds, with the clarity provided by nature, not enhanced or treated. We do not sell clarity enhanced diamonds that have been treated in any way. All our loose diamonds are handpicked and double checked by professional gemologists to ensure they are 100% natural.

The Gemological Institute of America (GIA) created the 4Cs grading system for diamonds – color, cut, clarity and carat weight. As the GIA is renowned for having the strictest and most consistent grading standards of the leading labs, the GIA certificate is considered the benchmark when assessing a diamond’s quality.

When you purchase a GIA certified diamond, you have the confidence of knowing exactly what you are buying and how much you should pay, based on current market comparisons. The diamond comes with a GIA certificate, which guarantees that you have purchased a high quality natural stone, rather than a synthetic stone or a fracture-filled stone that can seem deceptively bright.
