This sapphire is not as pleochroic as my other items Code 16 and Code 20. But it is still a very pretty gem.
This is what sapphires look like when they are dug out of the soil. They are dull and cloudy. The clouding is caused by rutile inclusions.
Most sapphires are routinely heated to improve the clarity. At high temperatures the rutile dissolves and disappears into the matrix. This results in a clear gemstone. The dissolved rutile also improves the colour, because rutile is titanium dioxide, and the titanium ion together with iron ion provides the typical cornflower blue colour of blue sapphires. Purple sapphires have traces of chromium and vanadium in addition to the titanium and iron. It is the balance of these trace elements that determine the particular shade of purple in purple sapphires.
The colour of this sapphire may remind you of amethyst, but that is where the similarity ends. Sapphire is a corundum, so it has a much higher refractive index than amethyst. This means that it has much more glitter, flash and fire than an amethyst. A dark amethyst is pleasant to look at in bright sunlight, but is quite dull in a dark room. The opposite is true of purple sapphires. They are painful to look at in bright sunlight, because they sparkle so much, but are very attractive in shade or indirect lighting.

Shipping All items are sent by S.A. Post Office Registered Mail. I will combine items at no extra cost. Certificates I don't offer a certificate because my gems are not particularly valuable. The courier charges and the lab report would cost more than the gems are worth. In my opinion, most valuation certificates are wildly optimistic and hopelessly unrealistic about the estimated retail value of the appraised gem. Try selling it for the quoted value! The only reason for quoting such an inflated value is to make the buyer feel good about buying the gem at a price much below "market value", i.e. the buyer thinks he is getting a bargain Payment BoBPay EFT only.
