The stone

A lab-grown diamond is diamond: pure carbon in the same crystal structure, with the same hardness of 10 and the same fire as a mined stone. The difference is origin; it is grown in weeks in a controlled environment rather than over billions of years underground. More in our guide to buying jewelry that lasts.

A gemologist’s note

A single diamond on a fine chain is the most worn necklace in fine jewelry because it goes with everything. Half a carat is large enough to be seen across a table, and the setting is fixed so the stone sits centered at the collarbone.

Care

Skin oils cling to diamond and dull its brightness. Soak in warm water with mild soap and brush gently behind the stone. Check the prongs once a year.
