The Diamond Guide

A quiet record of the earth.

Colour in diamonds forms through extraordinary geological circumstance — emerging uniquely in every stone. Here is how to read it.

Niram · The Colour

Why coloured
diamonds.

In moving beyond the convention of colourless brilliance, ALAGI embraces natural coloured diamonds for what they are — rare, warm, and one of a kind. Colour emerges uniquely in every diamond; no two are ever truly alike.

Each is shaped by time, chance, and the earth itself — carrying a quiet record of internal processes that unfolded over millions of years. The cut is chosen not for spectacle, but for soul.

The Palette

Four ways to glow.

Warm champagnes, soft pinks, golden canary yellows, deep cognacs — chosen to echo undertones, to enhance warmth, to belong effortlessly on Indian skin.

Canary Yellow

The sun in a stone.

The house signature. Glows warmest against deep, luminous skin.

Soft Pink

Felt, completely.

Rare and romantic — ROJA is built entirely around it.

Deep Cognac

Grounded. Certain.

Earthy depth, for the woman who knows herself.

Warm Champagne

A whisper of colour.

Subtle warmth that belongs without announcing itself.

Cut & Setting

Read for soul,
not spectacle.

Rose Cut

A softer, flatter facet pattern that glows rather than sparkles — intimate light, full of warmth.

Full Cut

Maximum brilliance and fire, chosen where the stone is meant to carry the whole composition.

Illusion Setting

ALAGI's signature — settings that amplify a stone's colour and presence, making it appear larger and more alive.

Fancy Shapes

Pear, oval, marquis, cushion, heart — cuts chosen for meaning, the way Tamil tradition always has.

Prong Setting

Minimal metal, maximum light — letting the diamond, not the gold, be the subject.

Bezel Setting

A clean rim of gold around the stone — quiet, modern, and built for everyday wear.
