About Purple Amethyst as a Gemstone
Amethyst is the purple variety of quartz, coloured by iron impurities together with natural irradiation. Tone ranges from pale lilac to deep, almost inky violet. Historically it was as valued as ruby and emerald until large South American deposits made it widely available. You can read more via gemmological reference, mineral data.
Amethyst lines cavities in volcanic rock, forming the geodes that can stand taller than a person in parts of Brazil and Uruguay. Crystals grow inward from the cavity wall, which is why colour is often concentrated at the crystal tips.
Why You Will Love This Gemstone
💎 Faceted Polish
The facets are clean and meet at sharp intersections, allowing light to bounce predictably through the pavilion and out the crown of the quartz.
✨ Setting Suitability
The hardness accommodates standard bench techniques, making it a reliable choice for custom gold or silver work designed for regular wear.
🔷 Colour Saturation
The purple hue distributes evenly across the entire pavilion, showing minimal zoning when viewed directly through the table facet.

Frequently Asked Questions
What are the exact measurements of this Purple Amethyst?
This stone measures 17 x 15.9 x 13.1 mm and weighs 21.7 carats. Those figures are taken from the stone itself, not estimated from a category average.
How does this quartz behave in a bezel setting?
Quartz holds an edge well and accepts standard metal pushers easily. Your setter can push a thick bezel wall over the girdle without chipping the stone.
Is this hardness safe for daily wear jewellery?
The mineral stands up well to normal daily use on the hand or neck. Keep it stored away from harder corundum gems to avoid surface abrasion over time.
What is the best way to clean this stone at home?
Warm soapy water and a soft brush will remove skin oils from the pavilion. Rinse thoroughly in clean water and pat dry with a lint-free cloth.
Why choose a radiant cut over an emerald cut for quartz?
The brilliant-style faceting pattern on the corners returns more sparkling light flashes than a stepped pavilion. It tends to brighten up medium purple tones effectively.
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.
Are your stones natural, or are any of them synthetic?
Everything we sell is 100% natural. We do not deal in synthetic or laboratory-grown material, and we do not hide anything about a piece: the photographs are shot to show every detail, including the ones a seller might prefer you did not see.
