Lab-grown diamonds under £500

Loose lab-grown diamonds under £500, in every shape and including many 1 carat stones, each with its independent IGI or GIA grading report. In lab-grown, the top colour and clarity grades cost little or nothing more, so a smaller budget still buys a beautifully graded stone.

Shop by budget: £500 to £1,000, £1,000 to £2,000, £2,000 and over or all loose diamonds.

Every loose diamond here has an independent IGI or GIA report and Excellent or Very Good polish and symmetry; nearly all are D–F colour and VS2 clarity or better, which is clean to the eye. The top grades cost no more in lab-grown, so the choices worth making are size, shape and proportion.
