1.

ONE STONE. FOUR RARITIES: 11.72 ct. Vivid/deep blue. Transparent. Untreated. It is the combination of all four qualities that makes this sapphire so hard to replace.

2.

NATURE GOT IT RIGHT: Heating is common in sapphires. This stone needed none. Its strong blue colour developed naturally and that untreated status can never be recreated later.

3.

11.72 CT CHANGES THE GAME: Large sapphires are rare. Finding this size together with strong natural colour, transparency and no heat narrows the available pool dramatically.

4.

YOU CAN'T ORDER ANOTHER: A mine cannot simply produce another 11.72 ct untreated vivid blue sapphire on demand. Future buyers must compete for what nature has already created.

5.

HISTORIC SOURCE. LIMITED SUPPLY: This sapphire comes from Kanchanaburi, Thailand, where most historic sapphire mines have closed, constraining fresh supply from the region.
