About this 1.02ct lab-grown round diamond

This 1.02ct lab-grown round sits in the classic one-carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG846647390 or 846647390. Listed at 3 retailers as of October 25, 2026, with prices from £174 to £228, a £54 spread on the same certified stone. Adiamor lists it at £228. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
