For centuries, Amethyst was considered a “Cardinal Gem,” ranked alongside Diamond and Ruby. While modern mining has made it accessible, finding a specimen that combines massive size (over 15 carats) with high-grade VVS clarity is still a significant gemological event.

We are proud to present this 15.5 Ct Purple Amethyst. This is not a standard cut; it is a Buff Cut Natural Loose Gemstone, a rare lapidary choice that transforms the stone into a deep, glowing pool of royal purple. For the collector seeking a statement piece that commands the room, this gem offers a unique optical experience.

The Science of the “Buff Cut”

To understand the unique beauty of this stone, we must look at its architecture. It is a hybrid between a Cabochon and a Faceted stone.

15.49 Carats of VVS Perfection

Weighing 15.49 carats with dimensions of 17.26 x 14.18 mm, this is a cocktail-sized gem. Usually, stones of this magnitude show inclusions.

However, this specimen is VVS (Very Very Slightly Included). This clarity is mandatory for a Buff Cut; because the domed top acts as a lens, any flaw inside would be magnified. The pristine nature of this crystal ensures the optical effect remains pure.

Durability & Wearability

Amethyst ranks 7 on the Mohs scale, making it harder than steel. It is more durable than Tanzanite or Opal.

The Buff Cut Advantage: The smooth dome of this cut actually makes the stone tougher than standard faceted gems. Facet junctions (sharp edges) are where stones usually chip. By removing the top edges, this Amethyst becomes incredibly resistant to daily wear and accidental knocks.
