Stones from the 90s when there was mining in this area. As far as I know all mines are closed since longtime. The Sapphires were found in a basaltic rock. All stones from this area were routinely heated (normal heat only):

Type: Sapphire

Colour: dark blue

Origin: Kanchanaburi/Thailand

You have a 7 day inspection period. Within the inspection period you may return the stone (unaltered) on your own expense for full refund. Please be so kind to contact me before returning items.

Please keep in mind that all purchases must be paid within 7 days. In the case that you need more time, e.g. you want to bid on more items, please drop me a line. All unpaid items will be canceled after 7 days and the bidder will be blocked.

EU buyers please add 21% VAT or provide me your VAT resale number. Unfortunately this tax cannot be added automatically in the checkout system of Gem Rock Auctions.
