C₁
Cut
Proportion & precision
Angles and proportions influence whether entering light escapes or returns through the crown as brightness and fire.
The architecture of light
Earth made it.
Light reveals it.
Carbon, pressure and geological time create the crystal. Human precision decides how beautifully it returns the light.

ROUGH CRYSTAL · DEEP EARTH
01 — Origin
Formed beyond the reach of daylight.
A diamond begins with carbon under extraordinary heat and pressure deep beneath the surface.
The source page describes formation at roughly 150 kilometres below the surface, at temperatures above 1,000°C and immense pressure. Over geological time, volcanic kimberlite can transport crystals upward.
What arrives at the surface is known for exceptional hardness — but its visual character comes from what happens when light meets a carefully cut stone.

02 — The Four Cs
Four measures. One stone.
Cut, color, clarity and carat provide a shared language for describing a diamond’s characteristics.
C₂
Color
D through Z
The traditional grading scale describes the degree of color present in a white diamond, beginning with colorless D.
C₃
Clarity
Natural signatures
Internal inclusions and external characteristics are considered when describing how clear the stone appears under examination.
C₄
Carat
A measure of weight
Carat describes weight rather than visible dimensions. One carat equals one fifth of a gram.
03 — Brilliance
A geometry built to return light.
The source describes the round brilliant as having fifty-eight facets. Light entering the stone is refracted and reflected through its geometry. White brightness is described as brilliance, spectral flashes as fire, and changing flashes during movement as scintillation.
04 — Craft
From rough crystal to measured precision.
The transformation is presented as a sequence of study, division, cutting and final polishing.
STEP 01
Rough
The natural crystal is examined and its structure studied before material is removed.
STEP 02
Cleaving
The rough may be divided along its natural grain — a decisive stage in planning the finished stone.
STEP 03
Cutting
Facets are shaped and their angles controlled to establish the geometry that manages light.
STEP 04
Polishing
The surfaces are finished until the marks of the tool give way to clean reflective facets.
05 — Enduring
Made over time.
Remembered in light.
Discover the character of a stone through proportion, clarity, color and the craft that gives its light a path home.
