Fine Gemstones

The best gemstones for rings, particularly engagement rings are the hardest most durable stones such as Sapphires and Rubies (of the Corundum family). At a hardness of “9” on Moh’s hardness scale, they are the next most durable to diamonds and are the best gems to handle the rigours of everyday wear.

 

Sapphires cover a wide spectrum of colours. The vibrant mid blue of Ceylon and the royal blue of Australian are the best known colours, however sapphires come in beautiful golden tones, pinks, purples, greens, two tone colours (“parti colours”) - almost every colour imaginable except red.

 

Reds are the rarest colours and these are exclusively known as “Rubies”.

 

Next to the Corundum gems, comes the Beryl family. These include Aquamarine, Morganite (pinks) and the most valuable gem of all, Emerald.  Gems of the Beryl family are a little softer than sapphire and a little more brittle. They are beautiful gems that need to be treated with respect and care.

 

Semi precious gems are numerous and varied in their characteristics and include the quartz family such as amethyst (purple), citrine (yellow) smoky (brown) and other colours. There are also many less common gems, some of which can be quite valuable such as golden Topaz and Tanzanite (violet/purple) and Alexandrite (green/red colour change). these gems are quite valuable due to their rarity.
