Platinum Necklaces – The Pinnacle of Fine Jewellery, Hatton Garden Crafted

Platinum is the most prestigious and enduring metal in fine jewellery — naturally white, extraordinarily durable, and hypoallergenic. Unlike white gold, platinum requires no rhodium plating; its brilliant silver-white colour is entirely natural and will never fade, tarnish, or change over time. A platinum necklace from FineDiam is not simply a piece of jewellery — it is an investment in quality, craftsmanship, and beauty that will last a lifetime and beyond.

At FineDiam, every platinum necklace is handcrafted in our Hatton Garden, London workshop by expert jewellers who understand that platinum demands the highest standards of skill and precision. Each piece 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 platinum rings to find a perfectly matched set.

Why Platinum?

Platinum is one of the rarest and most valuable metals on earth — approximately 30 times rarer than gold. Its natural white colour is permanent and requires no plating, making it the most low-maintenance of all precious metals. Platinum is also the densest of the precious metals, which gives platinum jewellery a satisfying weight and solidity that is immediately apparent when you hold it.

Platinum is the ideal setting for diamonds. Its density and strength hold each stone more securely than any other metal, and its naturally white colour enhances the brilliance and fire of a diamond without any colour interference. For this reason, the world’s most important diamonds — including the Koh-i-Noor and the Cullinan — are set in platinum. Platinum is also completely hypoallergenic, making it the ideal choice for those with sensitive skin or metal allergies.

Our Platinum Necklace Styles

Platinum Diamond Solitaire Pendants

A diamond solitaire pendant in platinum is one of the most classic and coveted pieces in fine jewellery — a single, perfectly selected diamond suspended in a platinum setting, allowing the stone’s brilliance to speak for itself. Our platinum solitaire pendants are available in round brilliant, oval, and pear-cut diamonds, with both natural and lab-grown diamond options, all IGI and GIA certified.

Platinum Diamond Halo Pendants

A diamond centre stone surrounded by a halo of brilliant-cut diamonds in platinum creates a pendant with extraordinary brilliance and visual impact. The platinum setting enhances the whiteness and sparkle of every diamond in the design, creating a pendant that catches the light from every angle. Our platinum halo pendants are available in a range of centre stone sizes and shapes.

Platinum Gemstone Necklaces

Platinum is a particularly beautiful setting for cool-toned gemstones such as sapphire, aquamarine, tanzanite, and blue topaz, where the metal’s natural white colour enhances the stone’s depth and brilliance. Our platinum gemstone necklaces feature a wide range of precious stones, all ethically sourced and carefully selected for their colour and clarity. Explore our full range of gemstone jewellery for matching pieces.

Platinum Chain Necklaces

A platinum chain necklace is a statement of understated luxury — its natural white lustre and satisfying weight make it a piece that is immediately recognisable as something exceptional. Our platinum chains are available in a range of link styles and lengths, and they work beautifully worn alone or as a setting for a pendant.

Platinum Necklaces as a Gift

A platinum necklace is the ultimate expression of love, commitment, and appreciation. Its rarity, durability, and natural beauty make it a gift that communicates genuine thought and care, and its timeless elegance ensures it will be treasured for a lifetime. Whether you are celebrating a milestone anniversary, a significant birthday, or a truly special occasion, a platinum necklace from FineDiam is a gift that will never be forgotten.
