On a ring worn every day, and especially on a hand that works, that hardness matters more than almost any other property. Our guide to what ruby means covers the history behind it.\u003c\/p\u003e\n\u003cp\u003eThis stone is lab-grown, with the same chemistry, hardness and optical behavior as mined corundum, in a saturated blood red. It is \u003cstrong\u003ebezel-set\u003c\/strong\u003e — the metal wraps the girdle completely rather than gripping it with prongs. That is the right call on a band worn hard: nothing catches, nothing snags, and there are no prongs to wear down.\u003c\/p\u003e\n\u003cp\u003eThe two pears flanking it are natural black onyx, 2 × 4 mm — opaque, evenly black, and the reason the red reads as vivid as it does.

The rhodium gives the bright white surface and shields the silver underneath from tarnishing.\u003c\/p\u003e\n\u003cp\u003eThe profile is a dome: rounded on the outside, flat on the inside, in a standard fit.
