Heat Treated Diamonds

Since Princess Katherine sported her stunning sapphire engagement ring back in 2010 the popularity of coloured stones in engagement rings has grown considerably. Sapphires, Rubies, Tanzanite’s, and coloured Diamonds are some of the stones that are quite often chosen as a central stone and can really given a very modern look as opposed to the classic diamond solitaire.

Many coloured stones are treated to improve the. This can be to produce a more unified colour, to intensify the colour, to change the colour of the gem stone completely or even to make the colour paler.

For centuries it has been well known that gemstones can be altered using heat, these days the techniques used can be extremely advanced and highly controlled. Heat treatment of stones is essentially a continuation of the natural development of the stone that occurs in the ground.

The heat treatment basically affects the stone by rearranging the crystal structure. In some cases, for example in the heat treatment of rubies, the stone can be heated up to near melting point creating a new crystal structure, giving the stone a deeper and more desirable colour of red.

The treatment means that the ring must not be heated up to very high temperatures (e.g. by a jeweller during resizing of the ring) or cleaned in an ultrasonic cleaner. Instead, special care needs to be taken when resizing these rings and the stone must be carefully removed and re-set during any future resizing work.
