About Purple / Gold Ametrine as a Gemstone
Ametrine is a naturally bicoloured quartz showing amethyst purple and citrine gold in a single crystal. The boundary between the two zones is usually sharp. Essentially all commercial ametrine comes from one source, the Anahi mine in Bolivia. You can read more via gemmological reference, mineral data.
The two colours arise from differing iron oxidation states within one crystal, produced by a temperature gradient during growth. Because the conditions required are so specific, natural ametrine is geologically unusual.
Why You Will Love This Gemstone
💎 Sharp Colour Zoning
The distinct boundary between purple amethyst and gold citrine is cleanly preserved through the facet arrangement, offering strong visual contrast in daylight.
✨ Bench Ready Cut
The precise facet angles and polished girdle allow your setter to mount this stone securely in standard prongs or a custom bezel.
🔷 Versatile Quartz Hardness
Standing high on the Mohs scale, this material resists everyday scratching well enough for regular wear in pendants and occasional rings.

Frequently Asked Questions
What are the exact measurements of this Purple / Gold Ametrine?
This stone measures 14.05 x 7.45 x 6.8 mm and weighs 5.38 carats. Those figures are taken from the stone itself, not estimated from a category average.
What setting style works best for ametrine?
Open-back bezel settings or multi-prong heads allow maximum light to pass through the stone, highlighting the natural split between purple and gold zones. Your jeweller can orient the bicolour divide vertically or horizontally depending on the mount.
How does ametrine compare to single colour quartz?
Ametrine is a natural variety of quartz that naturally contains both amethyst and citrine regions within the same crystal. It requires careful cutting to display both colours evenly in the finished piece.
Is this stone durable enough for daily wear?
With good resistance to scratching, this quartz variety handles daily wear reliably when set into protective jewellery styles like pendants or earrings. Rings should be worn with care to avoid hard impacts against abrasive surfaces.
How should I clean this faceted gemstone?
Wash the stone using warm soapy water and a soft bristled brush to remove surface oils from the pavilion facets. Rinse thoroughly with clean water and dry with a soft cloth.
How long does delivery take, and can I return it?
We contact you directly as soon as your order is placed to arrange delivery, so you always know where the parcel is. Returns are accepted within 7 days of the date you receive the item.
