Where every piece begins.

The origin, properties, and stories behind this season's most remarkable gemstones.

A lavender spinel — a soft violet-grey gemstone that shifts subtly in the light.

Lavender Spinel

Sri Lanka · Natural, untreated · 1 – 3ct

A soft violet-grey that shifts with the light, spinel spent decades mistaken for sapphire in royal collections before gemology gave it a name of its own. Untreated, and rarer at this clarity than most people realize.

A mint garnet — a cool, minty-green gemstone.

Mint Garnet

Tanzania (Merelani Hills) · Natural, untreated · 0.5 – 2ct

A cool, minty green found only in one corner of Tanzania, mint garnet is a tsavorite variant so rare it rarely leaves the region's specialist dealers. No heat, no fill — just what came out of the ground.

A Paraiba tourmaline in its signature electric, neon blue-green.

Paraiba Tourmaline

Mozambique · Natural, minor heat treatment common to the type · 0.5 – 1.5ct

The neon blue-green of Paraiba tourmaline comes from trace copper — a geological accident so unusual that gemologists once thought it existed in only one Brazilian mine. It glows even in low light.

A lab-grown alexandrite — a gemstone that shifts from green in daylight to red under warm incandescent light.

Alexandrite

Lab-grown, hydrothermal · Lab-grown, same optical and physical properties as mined alexandrite · 0.5 – 2ct

Green in daylight, red under incandescent light — alexandrite is the closest thing to a magic trick in the mineral world. Ours are grown, not mined, so the color-change performance comes without the six-figure price tag of a natural stone.
