Diamond Necklaces — 14K Gold & Sterling Silver

    Filter

      Diamond necklaces in solid 14K gold and .925 sterling silver, each one complete on its own chain at a stated length. The range runs from a single stone on a fine chain to pavé bars, clusters and open shapes set all the way round — and from natural diamonds to lab grown, which is the difference behind two necklaces that look alike and are priced very differently.

      See also all necklaces, necklaces and chains, diamond heart pendants, heart design necklaces, diamond slide pendants, sterling silver chains, Shey Couture necklaces, Black Hills Gold, diamond post earrings and silver diamond bracelets.

      More about diamond necklaces

      Natural and lab grown, and how to tell which you are buying

      A lab grown diamond is a diamond. It has the same carbon structure, the same hardness and the same optical behaviour as a mined one, and it is graded on the same scale — the difference is where it formed, not what it is. The practical consequence is price: a lab grown stone costs a fraction of a mined stone of the same size and grade, which is why the larger carat weights in this range are usually lab grown. Every product page states which it is, and so does the specification table on it. Neither is a substitute for the other; they are a choice.

      What carat weight actually tells you

      Carat is weight, not width. A 1/10 carat necklace spreads that weight across several small stones more often than it concentrates it in one, so two pieces at the same carat weight can look entirely different — a line of small stones reads as a continuous glitter, a single stone reads as a point of light. The total weight is on every product page, and where a piece carries more than one stone the count is there too. Both numbers matter more than either alone.

      Settings, and which survive daily wear

      A bezel wraps the stone in a rim of metal and is the most protective setting there is — the sensible choice for something worn every day and slept in. Prongs lift the stone so light enters from the sides, which makes it look larger and brighter, at the cost of edges that can catch. Channel and pavé settings sit the stones low and close together, which is robust, though a densely set piece has more places for dirt to collect. The setting is named in the specifications on each page.

      Gold and silver, and what the stamp means

      The gold here is solid 14K — 58.3% pure gold, stamped 14K — not filled and not a coating over something else. The silver is .925 sterling, stamped 925, and much of it carries a rhodium finish: a hard white metal from the platinum group applied over the silver, which keeps the white of the metal matched to the white of the stone and slows the tarnishing silver does naturally. Rhodium is a finish on top of real silver, not a substitute for it.

      Common questions

      Are lab grown diamonds real diamonds?

      Yes. A lab grown diamond has the same carbon crystal structure, hardness and optical properties as a mined diamond and is graded on the same scale. The difference is where it formed. It is not a simulant like cubic zirconia, which is a different material altogether.

      Why is one diamond necklace so much cheaper than another the same size?

      Usually because one is lab grown and one is mined, and the product page says which. Beyond that, price follows the total carat weight, the clarity and colour grades, and whether the stones are set in gold or silver.

      What carat weight should I look for?

      Carat is weight rather than size, and how it is distributed matters as much as the total. A tenth of a carat across several small stones gives a continuous sparkle; the same weight in one stone gives a single bright point. Both the total weight and the stone count are on each product page.

      Does the necklace come with a chain?

      Yes. Everything on this page arrives complete on its own chain, with the length stated on the product page. Several include a short extender, so the stated length is the longest setting.

      Which setting is best for everyday wear?

      A bezel setting, which surrounds the stone with a rim of metal and has no raised edges to catch. Prong settings let in more light and look brighter but are more exposed. The setting type is in the specifications on each product page.

      How do I clean a diamond necklace?

      Warm water with a drop of mild soap and a soft brush, worked gently around the setting, then rinsed and patted dry. Avoid silver dips and abrasive pastes: they strip a rhodium finish and can loosen stones in a channel or pavé setting.

      Will the sterling silver tarnish?

      Sterling silver darkens with air and moisture over time, and the rhodium finish most of these carry slows it considerably. A soft polishing cloth restores the shine. Store the piece dry and away from perfume, lotion and chlorine. Solid 14K gold does not tarnish at all.
