925 Silver Natural Amethyst Ring — Solitaire | Oval 1.8ct | UK O
Natural Amethyst Solitaire Ring in 925 Silver — Fixed Size UK O
A 1.8 carat oval-cut natural amethyst — 7×9mm — set in a classic four-prong solitaire on a solid 925 sterling silver band. The stone sits elevated in an open-back setting, allowing light to pass through from every angle and drawing out the full depth of its violet-purple colour. At 2.54 grams total weight, it has a refined, balanced feel on the finger. This is a fixed-size ring, sized precisely at UK O — if you know your size, this one fits perfectly from day one.
✦ A stone with a story. This amethyst was hand-selected through JewelHub's gemstone trade connections in India — sourced through decades of relationships rooted in Hong Kong Jade House, a family jewellery business with generations of gemstone expertise. Every stone in this collection has been chosen by eye, not algorithm.

Questions & Answers
Is this a real amethyst or synthetic?
This is a genuine natural amethyst — untreated and unenhanced, hand-selected through JewelHub's gemstone trade connections in India. It is not lab-created, synthetic, or colour-enhanced.
This is a fixed size — how do I know if it will fit?
UK O measures 17.5mm inner diameter with a 55mm circumference. To check your size at home, wrap a thin strip of paper around your finger, mark where it overlaps, and measure the length — 55mm means UK O fits you. If you're between sizes, size up slightly for comfort, especially on warmer days when fingers tend to swell.
Is the silver genuine 925?
Yes. The band is solid 925 sterling silver, hallmarked S925 on the inner shank. This is the same purity standard used in fine jewellery and meets UK assay standards.
Will the silver tarnish?
All sterling silver naturally develops a patina over time, particularly with exposure to moisture, perfume, or sweat. To keep it bright, store in a dry pouch when not wearing, avoid contact with lotions and chemicals, and polish gently with a silver cloth. Tarnish is fully reversible and does not affect the quality of the metal.
Is this suitable as a gift?
Yes — amethyst is the birthstone for February and is associated with calm, clarity, and intuition. The classic solitaire design works for birthdays, anniversaries, or as a self-treat. Every JewelHub order includes a JewelGift™ surprise at no extra cost. See our gifting packaging options here.
How should I care for this ring?
Clean gently with a soft damp cloth. Avoid ultrasonic cleaners, harsh chemicals, and prolonged water exposure. Amethyst sits at Mohs 7 — hard enough for daily wear but can chip if knocked sharply. Remove before heavy manual activity.

Silver tarnishes with air. That is normal, and it polishes off.
