How to invest in precious stones ?

For invest in precious stones, you can buy and store them in a bank vault, or turn to portfolio management, by a trader or wealth manager with expertise in these tangible assets.

Each option has its pros and cons, but the first step to this long-term investment is always to understand how the gemstone market works.

Choose a trader, manager or buy gemstones for investment requires understanding what influences the value of stones, what the risks are (such as fluctuations in demand, counterfeiting, etc.), what the best times are for resale, for example at auction, or for withdrawing funds.

Which precious stones for an investment ?

The market includes hundreds of types of stones, formerly called "fine stones," some of which are bought and sold at prices much higher than diamonds, emeralds, rubies, and sapphires, historically called "precious stones."

It is important to know the trends, as well as the most stable options, the latter of which can depend on the provenance. But each gem has unique characteristics and when you want buy gemstones, we must compare them.

A gemological laboratory certificate is essential, sometimes two (GIA, LFG, etc.). The safe haven is diamonds, but it is absolutely essential to diversify this heritage, for example, with spinels, tourmalines, aquamarines or tsavorites.

‍

Which stone is the most valuable ?

THE gemstones for investment are preferably unheated, cut and absolutely untreated. The price of a gemstone depends on its clarity, color, cut and carat, but also on its country of origin.

Some varieties are rare and, when they are of excellent quality, they are very valuable gems. For example: a Paraíba tourmaline, a Padparadscha sapphire, a Mahenge spinelIf the provenance is reputable, they can increase in value over the years.

‍

Does a precious stone retain its value ?

It is possible toinvest in gemstones by minimizing risks. The best way is to be accompanied by a renowned gem dealer or gemologist, in addition to knowing the market. Stones tend to retain their value, like some diamonds, Burmese rubies or Colombian emeralds.

Precious stones whose deposits are becoming depleted are increasing in value, such as Ceylon sapphire, alexandrite or tanzaniteDemand is a key element in the value of a stone, which is not, however, directly impacted by stock market fluctuations, interest rates or inflation.

The designs are super well done and the whole team remains very attentive to changes that need to be made if necessary. Mr. Deprez was also able to adapt perfectly to the budget he was given.
The rings are of impeccable quality. We will definitely use them again for other projects!"
