COMMENTS Two of these have sold, leaving two sapphires in the much sought-after teal blue and teal green colours. There are some variations in colour from stone to stone, however the colour is all natural; they have not been treated in any way, including heat. The lapidary has selected a brilliant round cut which traditionally maximises light return and brightness; the reason why it is so popular with diamonds. As a result, these stones face up bright and lively. The gems could be incorporated into one piece of jewellery, or set individually.
Commercial quantities of sapphire have been mined for more than 100 years in numerous locations situated along the Great Dividing Range in Eastern Australia, from Tasmania to North Queensland. Major commercial deposits occur in the New England District in northern NSW – Inverell and Glen Innes – and the Central Queensland Gemfields – Anakie, Sapphire, Rubyvale and The Willows, as well as Lava Plains in North Queensland. Besides professional operations, there are many part-time artisanal hand miners and hobby fossickers on the Gemfields.
DURABILITY Sapphire’s high hardness – 9 on Mohs scale – and its excellent durability render it ideal for most types of jewellery settings.
