Bellataire Type IIb Diamonds

Although diamonds are made of Carbon, no diamond is 100% pure Carbon.  Gemologists categorize the different types of diamonds based on the absence or presence of either Nitrogen or Boron in the diamond lattice.  The rarest type of diamonds found in Nature have Boron in their structure – the pure Type IIb Blue Diamonds.  The saturation of the blue color is determined by the amount of Boron in each diamond.  The more Boron Nature put in, the more rich velvet blue color.

Large and small, the ultra rare blue Type IIb diamonds are among the most sought after gems by professional collectors and connoisseurs the world over.  The extraordinary prices paid for blue diamonds in auction house sales continue to rise, sale after sale.  All of these multi-million dollar blue diamonds are Natural Mined Type IIb Diamonds.  Our Blue Type IIb diamonds in are the same Natural Mined Type IIb’s as the multi million dollar gems, but have undergone Bellataire’s High Pressure High Temperature process to bring out their all-natural blue color.

The most famous of all Blue Type IIb diamonds is the Hope, which is in a permanent exhibit in the Smithsonian Museum in Washington, DC. With it’s special provenance, this diamond is virtually priceless!
