Certified Diamonds

In addition to our stones, our selection of blister diamonds includes investment diamonds certified by authoritative bodies such as IGI and GIA. Our pricing policy of the same treatment at both wholesale and retail allows you to buy certified diamonds at unprecedented prices.

Certified Diamonds are an excellent personal investment and a safe haven asset as well as a great gift idea. We deal only and exclusively in natural diamonds.

The blistered diamond is always shipped in excellent, elegant gift packaging of the highest impact. Gifting a certified blister diamond is an excellent gift idea for any occasion, free from the embarrassment of choice and taste, has a strong impact and is an excellent investment. Compared to sterling or gold bullion, which always remains a sound investment, diamonds have historically always risen, however slightly, and never depreciated. Since diamonds are not a publicly traded security, they are not affected by the sharp downturns in a crisis as gold is.

Tabacco Jewelry deals only and exclusively in Natural Diamonds, all our suppliers are certified " Conflict Free Diamonds" meaning that no rough diamonds from which they come have been mined in conflict zones.

We select only the highest quality diamonds, in the certificate found online you can also see details such as:

-Certificate Number
