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 ARCHITECTURAL EDIT
A castle battlement in gold — diamonds filling every notch of a ring built like a monument.
The Crenelle Diamond Architectural Band takes its design language directly from the medieval battlement — the alternating raised and recessed profile of a castle parapet — and translates it into a ring of rare structural intensity. Each crenellation is filled edge-to-edge with micro-pavé round brilliant lab grown diamonds; each raised merlon is solid polished gold. The result is a band that plays light and shadow against each other all the way around the finger.
Crafted For You
The band profile alternates precisely between raised gold merlons and recessed diamond-filled crenellations that repeat continuously around the ring. Each recessed section is individually paved with micro-set round brilliant diamonds by hand, requiring exceptional precision to maintain uniform diamond coverage across each curved notch. The gold merlons are polished to a high mirror finish that contrasts sharply with the diamond sparkle beside them. The inner band is smooth and comfort-fit; the 5mm width sits elegantly on the finger without bulk.
The Details
| Metal | Solid Gold |
| Purity | 10Kt · 14Kt · 18Kt |
| Diamond Weight | 0.30 CTW |
| Diamond Cut | Round Brilliant |
| Clarity | VVS / VS |
| Setting | Micro Pavé / Crenellated Band |
| Dimensions | ~5mm wide |
Style Notes
The crenellated profile gives this band tremendous textural interest when stacked — pair it between two plain bands for a striking mixed-texture stack that plays smooth gold against the geometric diamond notches. Worn alone, the band has sufficient visual weight for any finger. In white gold, the contrast between polished metal and diamond is especially sharp and graphic; in yellow gold, it reads architectural and warm — a reference to ancient masonry rendered in precious metal.
