Know Your Carat.
Your Guide to Fine Jewellery
Know Your Carat/Karat.
Two words. Endless confusion. Here is everything you need to know about gold karats and diamond carats; so you can choose with complete confidence.
First Things First
Karat vs. Carat — What is the Difference?
KARAT (Kt) — Gold Purity
Measures the purity of gold. The higher the karat, the more pure gold is in the alloy. This affects the colour, durability, and price of the metal. All Roomy's pieces are available in 10Kt, 14Kt, and 18Kt solid gold.
CARAT (ct) — Diamond Weight
Measures the weight of a diamond. One carat equals 0.2 grams. A larger carat weight generally means a larger, more impressive stone. Every Roomy's diamond is graded D–F colour and VVS–VS clarity.
Part One
Understanding Gold Karat
Pure gold (24Kt) is too soft for jewellery — it scratches and bends too easily. So gold is alloyed with other metals for strength. The karat number tells you exactly how much of the alloy is pure gold.

Part Two
Understanding Diamond Carat
Diamond carat is a unit of weight — not size. One carat equals 0.2 grams. Two diamonds at the same carat weight can look very different depending on how they are cut. Cut is what releases the brilliance.
What Carat Weight Looks Like
0.25ct — Delicate, subtle sparkle
0.50ct — Noticeable, elegant presence
1.00ct — Bold classic fine jewellery
2.00ct+ — Statement piece, unmistakable
The 4 Cs — Quick Reference
Cut — Determines brilliance and sparkle
Colour — D–F is colourless (the finest)
Clarity — VVS–VS means virtually flawless
Carat — The weight of the stone
The Roomy's Standard
Every Roomy's diamond is graded D–F colour and VVS–VS clarity. Placing them among the finest stones available. You are not buying a diamond that passes minimum standards. You are buying one that exceeds them.

THE LUXURY EDIT
Marquise diamonds arranged as windmills — over two carats in perpetual bloom.
The Windmill Marquise Diamond Eternity Band is an exercise in geometric brilliance at its highest. Groups of four marquise-cut lab grown diamonds are arranged in a pinwheel formation around the band — each set radiating from a central point, their points touching tip-to-tip to create interlocking floral star motifs that travel all the way around the finger. More than two carats of marquise diamonds in a design that turns the eternity band into something entirely extraordinary.
Crafted For You
Each windmill motif is formed by four matched marquise diamonds individually prong-set at 45° angles from each other — two pointing across the band, two pointing along it — their pointed tips meeting to create the interlocking star effect. The motifs are aligned and spaced precisely around the 9mm band to ensure the pattern completes perfectly at the join. Each diamond is individually hand-set by our karigars, who must account for the complex geometry of the overlapping points; this is one of the most technically demanding settings in our collection.
The Details
| Metal | Solid Gold |
| Purity | 10Kt · 14Kt · 18Kt |
| Diamond Weight | 2.08 CTW |
| Diamond Cut | Marquise |
| Clarity | VVS / VS |
| Setting | Prong / Windmill Motif Eternity |
| Dimensions | ~9mm wide |
Style Notes
The windmill marquise eternity is a piece for the collector — one that rewards close inspection with its geometric complexity, and impresses from across the room with its over-two-carat brilliance. Wear alone as an anniversary band or right-hand statement piece. It is particularly arresting in yellow gold, where the warm metal accentuates the elongated marquise silhouette and gives the pinwheel motifs an almost Art Nouveau quality.
