Birthstones
A birthstone for every month, and the jewelry it belongs in
The modern American birthstone list is a trade convention rather than an ancient law, and several months carry more than one stone. What matters more than the list is the stone itself: how hard it is, how it was used in the period you are buying from, and what it needs from you once you own it. Each month below covers all three, and ends with the antique pieces we actually have.

Birthstones make the easiest gift brief
A birth month narrows the choice to one stone and takes the guesswork out of it. Our gift guides go a step further and sort by who you are buying for and what you want to spend.
