Diamond prices reflect the stone’s origin, specifications and the offer available at the time. To make a useful comparison, start with the same shape and similar carat weight, then compare cut, colour, clarity, grading laboratory and appearance. A price without those details tells you very little.
What changes the price?
The Four Cs are a useful starting point. Carat is weight, not a measurement of how large the diamond looks. Cut and proportions influence how it handles light. Colour and clarity grades affect price, but the difference between two grades is not always equally apparent without magnification. Origin, treatments, the report and the individual supplier offer also matter.
Natural and lab-grown prices
Compare natural diamonds with natural diamonds, and lab-grown with lab-grown, before weighing the two options against each other. There is no fixed price per carat or universal saving that applies to every stone. See our natural diamond guide and lab-grown diamond prices guide for the differences and a dated website-listed example.
From a stone price to a finished-ring budget
Ask whether a displayed price covers the loose diamond, the setting or the finished ring, and whether VAT is included. Metal, side stones, the setting design and the work required can change the total. A simple budgeting illustration is a £3,000 total with £1,200 allocated to the setting, leaving £1,800 for the centre stone. These are illustrative allocations, not a quotation or a promise that any two components are compatible.
Check the current offer before deciding
Browse the diamond finder to compare the website’s displayed prices and specifications. Availability and price must be reconfirmed before an order or viewing is agreed. A dated example is a reference point, not a guaranteed market minimum. Buy for the jewellery you want to wear; do not assume its retail price will be recovered on resale.
For help balancing stone and setting costs, read our budgeting guide, explore made-to-order designs, or book an appointment and tell us the total you would like to work within.
