Diamond Investments - Investing in Diamonds

Fancy color diamonds are a class that demonstrates many unique characteristics that other assets do not. They are affordable, durable, and easy to conceal, transportable, and not subject to cartel control. There is no shelf life, they never lose their luster or shine and will look as good as new 100 years from the time they are originally polished. They have well established valuation methods, and can be appreciated and utilized on a daily basis.

However, perhaps one of the most interesting characteristics of fancy color diamonds is their price resilience in the face of adversity and long-term price growth. Currency debasement around the world has led to the “smart money” seeking hard assets – assets which cannot be created by a printing press or the tap of a keyboard; and it is well known that both literally and figuratively, there are not many assets harder than diamonds.

A buy and hold strategy in the stock market may not always bear fruit, however it seems that by looking back over the past three decades, that such a strategy in the fancy color diamond market promises to show a rewarding outcome. The reason for this is because every stone is unique. Buy a Ferrari and you can order the color of the paint and the upholstery; buy a fancy color diamond and you purchase a one-off, something exquisite that no one else currently possesses.

Price Definition

The price of a fancy color diamond is affected by a combination of so many factors, including:

  • Size: the price per carat of a 1ct stone will not be half the price of a 2ct diamond and certainly not 1/5th the price of a 5 carat stone.

  • Shape: certain diamond shapes are more expensive than others. Round is the most expensive, followed by Emerald and Princess. Assuming a similar clarity and color, a Radiant or Cushion shaped stone will cost less than a Round diamond.

Different diamond shapes

  • Clarity: stones with high clarity (IF-VS), will be more valuable than SI-I clarity stones.

  • Color: the most important factor in fancy color diamonds is the actual color. There may be two stones with identical specifications (same color grading, similar clarity, same shape, and similar size) but the color of the stone will determine its value. If the color of one stone is intense and the other weak, even though the specifications are very similar, the stone with the stronger color will be sold for a much higher price than the equivalent stone with a weaker color. With fancy color diamonds, color is the king!

There may be occasional price fluctuations caused by financial crises, seasonal factors in the diamond market, or world tragedies (9/11, tsunami, etc.); after all, the price of fancy color diamonds is also subject to human factors. However, gram for gram, millimeter for millimeter, fancy color diamonds hold more value than possibly any other element known to mankind.

Possibly the most desired color, pink diamonds are very rare and renowned for their strong investment potential.

So what can be gleaned from this data? In general, fancy color diamonds exhibited greater returns with less volatility than most asset classes.

Gold, which is currently on an enormous bull run, is up approximately 495% from its 2001 lows. It has had many corrections during its climb, with corrections of up to 30%. It took the price of industrial equities, as represented by the Dow Jones Industrial Average, almost seven years to surpass its high set in 2000 and today is still only 6% above those levels. High tech stocks as represented by the NASDAQ are still 46% below their high set in 2000.

Price corrections have been of a much smaller magnitude and rises more pronounced for the fancy color diamonds discussed in the previous five years than in the period preceding it. In fact, since 2002, the entire spectrum of fancy colored diamonds has seen annual price increases from 10% to 35%. Perhaps this is attributable to a greater and broader appreciation of this previously “unknown” market.

With supply limited and the Chinese, Indian, Russian, and Latin American markets beginning to enter the fray, the appreciating price trend for fancy color diamonds seems to be assured. And remember the old truism from the financial markets – The Trend is Your Friend.
