March — Aquamarine

We do not carry aquamarine yet, and we are not going to pretend otherwise. What follows are the stones we would wear in its place until we do.

Aquamarine is beryl — the same mineral as emerald, coloured by iron instead of chromium. Sailors carried it because it was the colour of water they wanted to see. The March list has kept it since the list was written.

Sky blue topaz sits closest to it: the same pale, cool, almost transparent blue. It is a different mineral and a different stone, and it is worth saying so plainly.
