About Hot Diamonds
Hot Diamonds is a British jewellery brand with its design studio in Berkshire. Its signature idea is simple: every main-line piece is made from 925 sterling silver and hand-set with a real diamond, then rhodium-plated so it keeps its shine and resists tarnish. Gemstone pieces use natural stones such as white topaz, malachite and mother of pearl.
The range covers necklaces and pendants, earrings, bracelets, bangles and rings, with most full-price pieces sitting between about £30 and £150. The HD x Golden Edit collection adds 18ct gold plating over sterling silver, while Silver Whisper is a sterling silver gift line (without diamonds) priced under £30, with bracelets for birthdays, new mums, bridesmaids and more. There is also Emozioni, a build-your-own coin necklace range, and a large outlet section with reduced older lines.
The business is run from Reading by Historic Originals Ltd, a company registered in 1996. Hot Diamonds is a member of the Responsible Jewellery Council and says around 60% of its jewellery is already made with recycled silver. Every order comes in a gift box with free luxury gift wrap, and UK orders go out on a next-working-day service.
