An investment in limitless profitability at the highest security standards; with the added bonus of a tax free purchase.



Diamonds offer some of today's best investment opportunities. Due to their beauty and scarcity, the demand for quality diamonds continues to surge year after year. For the last 50 years, this has helped diamond prices grow by an average annual rate of 14 percent as global supplies keep plummeting. Diamond mine discoveries are rare, existing inventories are dwindling, and the industry struggles to meet consumer demands. All of these things work together to make diamonds a highly profitable investment vehicle.



Diamonds are universally accepted as a standard of beauty and now they can also represent a solid investment opportunity. Since ancient times, royalty and members of high society have turned to these gemstones to enhance their appearance and social status with eye-catching radiance and awe inspiring clarity. New diamond mines have become uncommon and supply has not been able to keep up with the increased desires of a growing world population. Due to this, current values are not only historically stable, but remain likely to increase year after year. For example, in 1970 a 1.0 carat stone could fetch $6700, while today that same gem could be worth $25,000.



At Diamondxo, we are always ready to help you with guidance and information about general tax laws relating to the purchase and sale of diamonds. Here is an FAQ which provide a summary of the most common implications for investors. 1. Are diamonds subject to value added tax? As with most precious metals and jewelry, diamonds may be subject to value added tax, depending on the jurisdiction. If this is relevant in your area, we are obliged to include value added tax in the prices we invoice for your investment. However, this will only be necessary once you ask us to deliver your diamonds to an address located somewhere outside of the duty-free zones where we store your purchase for you in our high security vaults.
