Gemstone Necklaces – Colour, Character & Hatton Garden Craftsmanship

A gemstone necklace is one of the most personal and expressive pieces in fine jewellery. Where a diamond necklace offers brilliance, a gemstone necklace offers colour — and colour tells a story. The deep red of a ruby, the vivid blue of a sapphire, the rich green of an emerald, the regal violet of an amethyst — each gemstone carries its own history, symbolism, and beauty, making a gemstone necklace a gift that is as individual as the person wearing it.

At FineDiam, our gemstone necklace collection brings together a wide range of precious and semi-precious stones, all handcrafted in our Hatton Garden, London workshop by expert jewellers who select each stone for its colour, clarity, and character. Every necklace is UK hallmarked by the London Assay Office and arrives in a luxury FineDiam gift box, beautifully presented and ready to wear. Explore our full range of gemstone rings to find a perfectly matched set.

Our Gemstone Necklace Collection

Ruby Necklaces

The ruby is the gemstone of passion, love, and vitality — its deep red colour has made it one of the most prized stones in the world for thousands of years. Our ruby necklaces feature natural and lab-grown rubies set alongside diamonds in white gold, yellow gold, and platinum. Ruby is the July birthstone, making a ruby necklace a particularly meaningful gift for July birthdays and ruby anniversaries. Explore our ruby necklaces collection.

Sapphire Necklaces

The sapphire is the gemstone of wisdom, loyalty, and nobility — its deep blue colour is one of the most coveted in fine jewellery. Our sapphire necklaces feature natural and lab-grown sapphires in a range of blues, from pale cornflower to deep royal blue, set in white gold and platinum with diamond accents. Sapphire is the September birthstone. Explore our sapphire necklaces collection.

Emerald Necklaces

The emerald is the gemstone of growth, renewal, and elegance. Its rich green colour is unlike any other stone in fine jewellery, and our emerald necklaces celebrate that uniqueness with settings designed to showcase the stone’s natural depth and character. Emerald is the May birthstone. Explore our emerald necklaces collection.

Amethyst Necklaces

Rich, regal, and timelessly beautiful — amethyst’s deep violet hues have been associated with royalty, wisdom, and inner strength for centuries. Our amethyst necklaces are available in solitaire, halo, and drop pendant styles in rose gold, yellow gold, white gold, and platinum. Amethyst is the February birthstone.

Tanzanite Necklaces

Tanzanite is one of the rarest gemstones in the world — found only in Tanzania and estimated to be a thousand times rarer than diamond. Its extraordinary blue-violet colour makes it one of the most striking gemstones in fine jewellery. Our tanzanite necklaces are available in white gold and platinum with diamond accents. Tanzanite is the December birthstone.

Aquamarine Necklaces

Calm, luminous, and endlessly elegant — aquamarine’s serene blue colour evokes the clarity of tropical waters. Our aquamarine necklaces are available in a range of styles in white gold and platinum, and they make a particularly meaningful gift for March birthdays as aquamarine is the March birthstone.

Peridot Necklaces

Fresh, vibrant, and full of life — peridot’s vivid lime to olive green colour is one of the most uplifting in fine jewellery. Our peridot necklaces feature natural peridot set with diamond accents in yellow gold and white gold. Peridot is the August birthstone.

Opal Necklaces

No two opals are alike — opal’s unique play-of-colour, where flashes of red, green, blue, and gold shift and dance within the stone, creates a gemstone that is unlike any other. Our opal necklaces are available in white gold and platinum with diamond accents. Opal is the October birthstone.

Birthstone Necklaces

A birthstone necklace is one of the most personal and meaningful gifts you can give. Each month has its own gemstone, and a necklace set with someone’s birthstone carries a significance that goes far beyond its beauty. Our birthstone necklaces are available in a range of styles and metals, and our bespoke design service allows you to create a truly personalised piece. Whether you are celebrating a birthday, a new arrival, or a milestone anniversary, a birthstone necklace from FineDiam is a gift that will be treasured for a lifetime.

Gemstone Necklace Styles

Our gemstone necklaces are available in a range of styles to suit every occasion and preference. Gemstone solitaire pendants place a single stone at the centre of the design for maximum colour impact. Halo pendants surround the centre stone with a ring of brilliant-cut diamonds for added brilliance. Drop pendants allow the stone to catch the light with every movement. All styles are available with natural or lab-grown diamond accents, IGI and GIA certified.

Metal Options

Our gemstone necklaces are available in 9K yellow gold, 18K white gold, 18K yellow gold, 18K rose gold, and platinum. All metals are UK hallmarked by the London Assay Office. The right metal choice depends on the gemstone — yellow and rose gold enhance warm-toned stones like ruby, peridot, and amethyst, while white gold and platinum complement cool-toned stones like sapphire, aquamarine, and tanzanite.
