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.
