Type IIa Diamonds

 

Type IIa diamonds are the purest type of diamonds and the most valuable in the world. They contain either very little or no nitrogen atoms in the crystal structure.

White stones are exceptionally colourless, fancy coloured diamonds are often found with a brown, purple, blue, or pink tone.

Only 2% of all sourced diamonds found are of type IIa.

Whilst we hesitate to encourage our clients to buy diamonds purely for the purpose of an investment, a fancy colour diamond and especially a type IIa diamond has the potential for significant future gains in value.

There are various independent gemological testing labs across the globe such as IGI (International Gemological Institut) HRD (Hoge Raad voor Diamant) or GIA (Gemological Institute of America). GIA applies the highest grading standards in the trade and is the leading gemological laboratory in the world. It is the industry’s most trusted and most widely acknowledged service.Gemological Institute of America and for most of our solitaire diamonds and selected gemstones we provide a full GIA report specifying the weight, accurate measures and quality specifications.

 

Fancy Colored Diamonds
In diamonds, rarity equals value. With diamonds in the normal range value is based on the absence of colour. This is because colourless diamonds are the rarest.

With fancy colour diamonds the rarest and most valuable colours are saturated pinks, blues, and greens. In all cases, even very slight colour differences can have a big impact on value.

Compared to fancy yellows and browns, diamonds with a noticeable hint of any other hue are considerably more rare. Even in light tones and weak saturation, as long as they show colour in the face-up position they qualify as fancy colours.

Red, green and blue diamonds – with medium to dark tones and moderate saturations – are extremely rare.

Grading fancy colour diamonds is complex and specialised. It takes highly trained laboratory graders to complete the process accurately.

All our solitaire diamonds and selected gemstones are certified.
