Diamonds are separated into two different types Type 1 and Type 11a
Type 1 diamonds contain nitrogen while Type 11a are nitrogen free and are usually white brown or pink and very rarely red or green
Type 11a and Type 11b (blue colour) are very rare and are generally thought to comprise less than 1% of all diamonds
Because of the absence of nitrogen Type 11a diamonds can never be yellow
While it is possible to obtain D Flawless diamonds from Type 1 diamonds,the most sought after are Type 11a Flawless diamonds
Type 11a diamonds have superior optical properties and have a superior overall polish to Type 1 diamonds
