Details
Two ribbons of gold cross into an infinity and resolve into a heart, with a single 3 mm natural diamond held on four prongs where the loops meet. It is the clearest way to say permanent without engraving a date on anything.
At 18 mm wide it has real presence, and about 3.16 grams in 14K white gold — 4.56 grams in platinum — means the loops hold their shape rather than flexing every time it catches on a collar.
Every piece hangs on one adjustable cable chain worn at 16 or 18 inches — the 16 and 18 inch options are the same chain, so you set the drop where you want it. It is solid 14K gold on the gold options, and solid platinum on the Platinum option.
An anniversary piece: the tenth, the twenty-fifth, or the one you were not sure you would reach.
Diamond and gemstone carat weights are approximate and may vary slightly from the stated figure. Pendant dimensions are nominal.
