Natural or synthetic ?
They have the appearance, the brilliance and the hardness of natural diamonds, but they do not have their value: these are synthetic diamonds.
Synthetic diamonds have been manufactured for industrial purposes since the 1950’s. Nowadays, they are becoming increasingly popular in jewellery, which may cause confusion and lead to fraud.
