Top grade lab-grown diamonds

In lab-grown diamonds, the very top grades cost no more. At the same size, our D–E, IF–VVS2 stones are priced about the same as lower grades, so you can choose the finest colour and clarity without paying a premium.

D and E are the two highest grades in the colourless range (D–F); any trace of colour can only be picked out by an expert comparing stones side by side. IF (internally flawless) diamonds show no inclusions under 10× magnification, and VVS1–VVS2 inclusions are so small that even a skilled grader finds them hard to see at 10×. Every stone comes with its IGI or GIA grading report. How we grade 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.
