The offer of auction houses

The most exceptional and outstanding jewellery and diamonds are usually collected and stored by famous auction houses, until a major auction is held. This way, there is a varied offer to meet the various tastes of the interested investors.

When a particular type of diamond is auctioned regularly, this may indicate an over-offer on the market. On the one hand, this obviously has a direct negative impact on the price of those diamonds. On the other hand, this can also be a way of auction houses to solve a sudden higher demand. The price of diamonds is always determined by the demand of investors in the market, as the offer remains quite stable.

Rare green diamonds

At the latest auction of Sotheby’s in April, a handful of coloured diamonds was auctioned. To put this auction in the spotlight, Sotheby’s sold a very rare green diamond. This was a unique opportunity for investors, as only 1 in 10,000 green diamonds are named “fancy coloured”, and this was a diamond of the purest colour grade.

The diamond’s price was estimated between one and a half million dollars. The diamond was set into a beautiful ring, accompanied by two triangular cut colourless diamonds on the side. The green diamond itself weighs about 1.64 carat.

The gradation and price of coloured diamonds

The colour and thus the price of a diamond is determined by the extent to which the diamond’s colour differs from completely colourless. Light yellow is one of the most common colour tones in diamonds. The GIA colour scale is used to express the colour.

Investors who are interested in diamonds can always be advised by BNT Diamonds experts for objective advice and guidance.
