What sort of diamonds do we buy?
We buy diamonds that are:
Over 0.15 carat
Loose or set in jewellery
In good condition
We will make an offer on all diamonds and gemstones in prime condition based on the quality. Unfortunately we are unlikely to make an offer on precious stones in a poor condition, so it is advised that you hold on to these. However, if your stone is attached to a piece of gold, then you can still sell your gold for cash! All you need to do is remove the diamond to keep and send the remaining gold to us.
How are diamonds valued?
We determine the value of your diamonds using the 4 C’s used to categorise all precious stones.
This is the style or design of the stone and refers to the symmetry in the stone as well as the shape (for example pear or oval cut). It is said to be the most important of the four C’s. This is because it affects the way light enters the stone and how many times it is reflected before leaving the stone. To the observer, the more times it is reflected the brighter the stone looks.
This refers to the quality of the diamond, its visual appearance including how many inclusions or imperfections there are and the number of surface defects known as blemishes. There are many grades of clarity which are determined by looking at the stone at 10x magnification.
Diamonds vary in colour however the whiter the diamond, the more it is worth. If a diamond appears more yellow, it means it has more impurities which lowers the value. Diamond colour is usually determined using a spectrum.
Carat is the unit of measurement used to weigh diamonds - 1 carat is equal to 200mg. Diamond prices are calculated as a price per carat, so the higher the carat weight, the more the diamond is worth!
