Diamond and jewellery price guide
Where our range starts, and what moves the price.
From the CTJ Jewellery team, led by founder Greg Ward
We aim to price competitively from the outset rather than rely on frequent discounting. Every price depends on the diamond, metal and design you choose, and every quote is based on the actual diamond and piece.

What moves the price
Carat weight
Price per carat rises at popular weights such as 0.50, 1.00, 1.50 and 2.00ct.
Cut and shape
Cut quality drives how a diamond looks. Round carries the highest price per carat.
Colour and clarity
Each grade up costs more, even where the difference is hard to see.
Origin
Size for size, lab-grown diamonds sit at a lower price than natural.
Comparing prices fairly
Compare more than price alone. Look at diamond quality, cut performance, craftsmanship, after-sales support and whether you can see the diamond before you buy. We help you compare like for like, and where it helps your budget we suggest alternative sizes, metals, or both natural and lab-grown options.
