Star Lab-grown Diamonds
The star cut is a specialist fancy shape with points radiating from a central body — rarely used as a centre stone, but striking as an accent or in a piece built deliberately around it.
Shapes this unusual are cut in tiny numbers, so availability moves constantly here. Lab-grown diamonds are chemically, physically and optically identical to mined stones, certified to the same standards and typically 60-80% less per carat. Our lab-grown diamond guide covers the detail. Compare it with every other outline in our diamond shapes guide, and get to grips with what actually drives price in our diamond 4Cs guide. All our stones carry independent laboratory certification and transparent pricing, and our London team will talk you through any of them with no obligation.
