Which Colored Diamonds Should I Invest In?

Posted by Tony Cathaway on 9/21/17 9:35 AM

After stressing the advantages of considering fancy colored diamonds as alternative investments, many of you contacted us and asked us which colored diamond category you should invest in accordance to your budget. Since this is one of our most frequently asked questions, we figured it was high time we shed some light on the matter.

In the following paragraphs we will be exploring which colors comprise each one of the categories, as well as their value in $/carat in order to help you find the ideal stone to match your budget.

Three Things Before We Begin:

  1. No jewelry or historical value will be assessed in this article. We will be comparing only loose stones.
  2. A proper side by side comparison requires all things being equal. We will be comparing stones based on their color and its rarity. For all intents and purposes, stones regardless of color will be considered to be of equal carat size, cut quality, and clarity.
  3. All prices per carat will be measured using “eye-clear” clarities as a benchmark.


Diamond Color Categories According to Rarity

For those who didn’t know, colored stones are extremely rare comprising only 0.1% of all diamonds mined globally. Among this 0.1%, there exists a hierarchy of color rarity. Some colored diamonds are so rare that only a handful of them have ever been documented. While on the other hand, some are so abundant that their volume alone can dictate fairly affordable prices, even less than their colorless counterparts.

Starting from least to highest, the hierarchy of colored diamonds regarding their rarity (and therefore, their price) looks something like this:

  • Common colors: Black, Brown, Yellow (up until Fancy Yellow grading)
  • Rare colors: Orange and Yellow (Fancy Vivid and Fancy Intense Yellow grading)
  • Very Rare: Green, Pink, and Blue
  • The most rare of them all: Red

Again, note that this categorization of value holds all other 3Cs equal, as a 10 carat, Internally Flawless, Fancy Vivid Yellow diamond can easily fetch a higher price when compared to a 1 carat, Light Pink stone with inclusions.

Common Colors

While still rare, the commonality of these stones compared to other colored diamonds on the list is significantly higher and therefore dictate much more affordable prices. As a “low end” purchase, these diamonds can be considered fine alternatives to their clear counter parts. Now by all means, when saying “low end”, we do not mean low quality. Many of these stones still hold a remarkable beauty and can be used to create fine pieces of jewelry or even engagement rings.

Stones in this category with an “eye-clear” clarity can yield prices ranging in the 4 to 5 figure range per carat. Of course prices can fluctuate in accordance to size, quality, and craftsmanship of the stone (4Cs).

Rare Colors

This category belongs to the mid-to-high price range. This is mainly due to color intensity and the existence of modifiers and undertones. Unlike the yellows of the previous category, Canary Diamonds (Intense Yellow and Vivid Yellow) are highly sought after and their rich and vibrant color can oftentimes fetch prices on par with top quality clear stones, and in some instances even surpass them by a great margin.

Pure Canary Diamonds will yield price premiums, while stones with gray or brown modifiers or undertones will yield discounts.

Similarly, pure Orange diamonds can fetch high prices prices; these stones are extremely rare. The most commonly found orange diamonds have modifiers such as brown or yellow. Even though these modifiers are unfavorable and will yield price discounts, they are still considered more valuable than their clear counterparts (all other Cs being equal of course).

If you still want to buy a rare colored diamond, consider looking for darker colored stones or those with dark undertones. This will hide any inclusions a diamond might have and you can settle for a stone with a lower clarity grading that still looks beautiful.

Very Rare

This category is comprised by the most rare colors in the world; colors we're used to seeing displayed in museums and sold at auctions for tens of millions of dollars. While this category can be further broken down into an internal hierarchy of its own, for the sake of time we will keep it simple.

Types of diamonds are sought after investors as a long term asset. They hold tremendous value and are an ideal alternative investment. Simply at “eye-clear” clarity prices can range drastically:

The following diamonds tend to start in the 5-figure per carat range.

  • Lime Green and Light Blue
  • Light Pink
These diamonds tend to start higher into the 6-figure range.
  • Pure Blue
  • Intense Green
  • Intense Blue
  • Intense Pink

In essence, the above can be considered a rough base line. Any attribute improvement (4Cs) such as more favorable cut, greater clarity, bigger carat size, and/or greater color intensity can cause exponential increases in price that will easily enter the millions of dollars per carat price range.

If you still fancy a diamond in this color category but don’t have the budget, there are still ways to obtain more affordable diamonds. Unfavorable undertones and modifiers, lesser color and clarity grading, lighter saturation, and smaller size all yield a price discount. Even when compared to a high quality D graded clear stone, a smaller, less clear, intense pink diamond will without a doubt still look incredible.

The Most Rare Of Them All

This category holds only one color which is in league of its own. Only a handful of these diamonds have ever been seen at public auction, and each yielded astronomical price tags.

Completely pure red diamonds are so rare, they're virtually nonexistent and yield price tags that break the $millions/carat benchmark. Even those with secondary hues such as brown and purple are capable of shattering the previously mentioned threshold.

In essence, an “eye-clear” pure red diamond can fetch 7-figures/carat. Any increase in quality will increase this ration exponentially. These stones are at the very top of the color hierarchy and will require massive amounts of luck, patience, and dollars to acquire one.

Let's put the rarity and value of the color red in these diamonds into perspective. If an “eye-clear”, brown gem from the first category has even the slightest inclusion of red as a color modifier (15-20%), its price will rise from 4 to high 5-figures/carat.

No other color in the naturally colored diamond spectrum has such a drastic effect as a modifier.
