Opal & Tourmaline
Two birthstones, one shared gift

Color in motionOpal plays it. Tourmaline holds it.

Opal is the only gemstone that performs: play of color, a shifting weather of reds and greens and blues inside one stone, and every Ethiopian crystal opal here is unenhanced. Tourmaline answers with the widest palette in the mineral world, pink to red to green to parti stones that carry two colors in a single crystal. Every treatment is disclosed, and unenhanced and unheated pieces lead the upper tiers.

Why opal and tourmaline

Two ways to hold colorThree reasons October runs deep here.

I

Play of color

Opal diffracts light into moving color, and no two stones perform the same scene. Every Ethiopian crystal opal here is unenhanced.

II

The full spectrum

Tourmaline runs every color the earth offers, and parti stones carry two at once. One species, a whole palette to choose from.

III

Nothing hidden

Treatment is always disclosed. Unenhanced and unheated stones lead the selection, and their rarity is the reason they lead.
