Diamond clarity enhancement is a process to improve the clarity of a diamond by the use of a foreign material, normally a type of glass, being forced under pressure into open fissures, cracks and other surface reaching characteristics on the surface of a polished diamond.
Diamonds listed on www.diamonds.co.nz are not clarity enhanced and we would never supply these diamonds to our clients.
Our main area of concern is that they are actually not what they appear as the process can improve the clarity and appearance of the diamond by a number of clarity grades. Yes, the majority of clarity enhanced diamonds are disclosed when initially sold but with any further sales this disclosure can get lost.
Also there is a considerable risk in damaging the diamond and returning it to its original clarity while under repair, as the majority of clarity enhanced diamonds cannot withstand the heat of a jeweller’s torch.
