Buying diamonds with Nellys Diamonds
Diamond, grown
Every Nellys Diamonds stone is laboratory-grown: the same carbon crystal as a diamond from the ground, with the same hardness, fire and sparkle. The difference is where it forms, in a matter of weeks, under the same intense heat and pressure, rather than over millions of years underground.
The 4Cs
Cut, colour, clarity and carat still decide how a laboratory-grown diamond looks and what it costs. Our specialists will explain each one and show you stones side by side, so you can decide what matters most to you.
Made to order
Most pieces can be made in a different metal, carat weight or shape, and we’ll help you find the right ring size. If you can’t see exactly what you’re looking for, book a consultation, in person or by video. Engagement rings and custom pieces are made for you and take 4 to 6 weeks.
