Pale green amethyst, cut with crisp geometric precision.
These elegant 9ct yellow gold stud earrings each feature an elongated octagonal green amethyst, secured in a minimal four-claw setting that leaves the gemstone almost completely open to the light.
The fancy cut creates a striking starburst effect through the stone, giving the soft mint-green colour far more presence than a conventional cut. Clean, contemporary and quietly unusual, they’re an easy everyday way to wear something a little different.
Part of The Gemstone Gift Edit.
We love how much character comes from the cut alone.
The green amethyst is subtle in colour, but the elongated octagonal facets create beautiful movement and reflection as the earrings catch the light. The yellow gold claws add warmth without distracting from the gemstone.
They also pair perfectly with the matching necklace for a polished, contemporary set.
The House of Gemstones
Amethyst is loved for its unmistakable purple colour, from soft lilac and lavender through to velvety violet and deep royal purple.
Its beauty, durability and variety make it one of the most versatile coloured gemstones, equally at home in delicate everyday jewellery and bold statement pieces.
Nature’s Artistry
Amethyst commonly forms as purple crystals lining cavities and geodes within volcanic rock.Clean amethyst with lukewarm water, mild soap and a soft brush. Avoid sudden temperature changes, hard impacts and prolonged exposure to intense sunlight.
Understanding Amethyst Colour
Soft, airy purple with a delicate pastel character.
A balanced medium purple with attractive brightness.
Rich saturation that remains lively rather than overly dark.
Purple with warm red flashes, often attractive under incandescent light.
Origins and Character
A major source producing crystals in a broad range of sizes and purple tones.
Often associated with smaller crystals showing rich, deep purple colour.
Known for deeply saturated material with attractive blue or red flashes.
Famous for ametrine, where amethyst and citrine occur in the same crystal.
Two Colours, One Crystal
Ametrine is a natural variety of quartz displaying both purple amethyst and golden-yellow citrine in the same gemstone.
The cutter carefully positions the natural colour boundary so both tones remain visible and interact attractively in the finished stone. No two ametrines share exactly the same division of colour.
Understanding Treatment
Most amethyst is sold in its natural purple colour. Heat may be used to lighten the colour or transform suitable material into yellow, orange or greenish quartz varieties.
The characteristic purple colour developed naturally within the quartz crystal.
Controlled heating may change the colour, sometimes producing citrine-like tones.
Synthetic amethyst has the same basic composition but is created under laboratory conditions.
Marcus Tempus Gemstone Selection
We select amethyst for colour, transparency, brilliance and overall character. We favour stones that remain lively in normal light, whether softly lavender or richly saturated purple.
