Opaque Blue Sapphire. This is not a valuable gemstone, but it is an interesting gemstone; it is natural and untreated, unheated, and one can see with the naked eye, when the gem is turned in the light, the natural characteristic “silk” of Sapphire at glittery play. Sapphire “silk” is the term given to the natural microscopic rutile inclusions of Sapphire gemstones, lined up in formation and reflecting light, as woven silk material will do.

6.6 grams of solid 9ct Gold in this ring setting for the above Opaque Blue Sapphire, and a day’s work at the bench for a highly competent Sydney bench jeweller.
