The Stone

Understanding amethyst

Amethyst is the violet variety of quartz — the stone of Greek legend and of bishops’ rings, cut for its colour more than its fire. Our gemologists grade every amethyst on colour, clarity, cut and carat. Here is how to read them, and where this piece sits.

01Colour

LightModerateIntenseVividExceptional

Amethyst runs from pale lilac to a deep, saturated purple with flashes of red and blue — the colour once called “Siberian”. The deeper and more even the purple, the rarer the stone; a large stone of even colour, without zoning, is the prize.

02Clarity

IFInternally flawlessSISmall inclusionMIMedium inclusion

Our gemologists grade clarity in three steps: Internally Flawless — nothing to find even under 10× magnification; Small inclusion — a trace only a loupe reveals; Medium inclusion — a natural feature you may find with the naked eye, in a stone chosen for its colour. Fine amethyst is usually clean to the eye.

03Cut

Cushion

Trillion
Round

Amethyst is cut in every classic shape: cushions and ovals carry the colour, checkerboard tops and trillions add sparkle, and because good rough comes in size, cutters rarely have to compromise on symmetry.

Amethyst is one of the few gems where large sizes remain within reach, so weight matters less than colour: a ten-carat stone of deep, even purple is worth far more than a pale twenty.
