Apatite

Apatite is a calcium phosphate — the same mineral family as tooth and bone — that, in gem quality, produces some of the most electric color in the mineral kingdom. The standout is a neon blue-to-green that mimics the famous (and famously expensive) Paraiba tourmaline at a tiny fraction of the price, which is why apatite is a longtime favorite of collectors who care more about color than hardness.

The catch is right there on the scale: at Mohs 5, apatite is soft. It will scratch and abrade with hard daily wear. That single fact shapes everything about how to use it — brilliantly suited to earrings, pendants, and occasional rings; not the stone for an everyday solitaire.

Color

Treatments

Most blue and green apatite is heat-treated to clarify and deepen color — stable and permanent. The neon material is typically natural in color. As always, we disclose treatment where it applies.

Daily wear

Treat apatite as a special-occasion or protected-setting stone. It is superb in earrings and pendants, where it never meets a countertop. In a ring, choose a bezel or otherwise protective mounting, expect to remove it for chores, and clean it gently — warm soapy water and a soft brush, never ultrasonic or steam.
