Round diamond solitaire pendant necklaces in gold, platinum and silver

A round diamond solitaire pendant holds a single diamond close to the heart. Wear it alone, or make it the first piece in a collection you add to over time.

Every solitaire is handcrafted in Britain from recycled precious metals, which reduces the need for new sourcing. Choose between ethically sourced natural diamonds, certified in line with the UN-backed Kimberley Process, or lab-grown diamonds that are chemically and visually identical, with the same brilliance, beauty, and quality.

Classic claw-set pendants sit alongside floating solitaires that hold the stone as if suspended, and illusion settings that give the diamond a larger presence. Metals run from nine and 18 carat white and yellow gold to platinum and silver, each proportioned to sit cleanly at the collarbone. Browse the range and find the diamond necklace that tells your story.

Our necklaces are crafted from high-quality, recycled precious metals including sterling silver, 18K gold vermeil, solid 18K gold, and platinum. Each product description details the metal used, so you know exactly what you’re buying.

Our chains are designed to be durable and long-lasting, made with high-quality precious metals. But like all delicate fine jewellery, they should be treated with care - avoid pulling or snagging on clothing to keep your necklace secure for years to come.

Yes, our necklaces are fitted with strong and reliable clasps, designed to hold your jewellery safely in place during daily wear. Many of our designs use spring-ring or lobster clasps, known for their durability and ease of use. When putting your piece on, always double check the clasp is securely closed, to avoid losing it.

We offer necklaces in a variety of lengths, from short, delicate chains to long pendants. Standard lengths are usually 16–18 inches, but exact measurements are listed on each product page.
