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.
