Precious Gemstones

Why acquire Natural Colored Diamonds or Precious Gemstones?


A word that has been gaining a tremendous amount of traction these past years. Record debt levels and record markets, coupled with volatility, are forcing many to look for a more conservative approach to wealth preservation. Fancy colored diamonds and precious gemstones are one of the oldest known ways to store and protect one’s money. It is the most concentrated form of wealth in the world. For centuries these stones have provided safety and opportunity, earning it the title Currency of Crisis.

Supply and Demand:

Top natural fancy colored diamonds have averaged a yearly gain of between 15% and 30% and there has not been a price decrease recorded. Supply and demand plays an integral role in pricing. A diminishing supply has occurred due to lack of new mining opportunity. Markets with high understanding of hard assets such as China and India have helped to increase demand. With the anticipated future closure of the Argyle Mine in Australia, the next several years appear to have the supply to demand gap widening.


Natural colored diamonds and precious gemstones are not a speculative endeavor. Institutional investors and funds have been unable to use these assets in risky trading platforms. Not having the traditional markets speculate in this asset class has allowed for consistent growth as opposed to volatile swings in price. Supply, demand and the availability of quality are the guiding principles.

Portable and Discreet:

Unlike other assets, you can move millions of dollars in the palm of your hand. No other form of wealth can boast of this portability. Being an unregistered asset also adds to the discretion that is so attractive for many. Natural colored diamonds and precious gemstones are easily transferred between generations enabling for a seamless passing of wealth.
