Light does not
pass through.
It transforms.

Rare crystal specimens, scientifically certified

The Collection

Three specimens.
Three million years.

SPX-001

Alexandrite

The chameleon stone. Emerald in daylight, ruby under incandescent — a chromatic impossibility born 65 million years ago.

Hardness 8.5 Mohs
Refractive Index 1.746 – 1.755
Origin Ural Mountains, Russia

SPX-002

Paraíba Tourmaline

Neon blue-green copper elbaite. Found in 1989, never seen before. Glows under its own internal light — a colour without precedent.

Hardness 7.0 Mohs
Refractive Index 1.624 – 1.644
Origin Paraíba State, Brazil

SPX-003

Imperial Topaz

Saturated orange-gold with a salmon overtone, once reserved for Russian czars. Fewer than 1% of all topaz achieves this grade.

Hardness 8.0 Mohs
Refractive Index 1.619 – 1.627
Origin Ouro Preto, Brazil

Every colour
was always
inside the light.

Dispersion is the separation of white light into its spectral components. The higher a crystal's refractive index, the more dramatically it bends each wavelength — splitting light into the full visible spectrum. This is what we chase.

Each specimen
is unrepeatable.

We do not sell certificates. We transfer custody of geological events. Every specimen arrives with full provenance documentation, independent gemological certification, and a climate-controlled display vessel.
