About this 1.01ct lab-grown round diamond

This 1.01ct lab-grown round sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LGS2H66208 or S2H66208. Listed at 2 retailers as of October 31, 2026, with prices from £783 to £1,353, a £570 spread on the same certified stone. Yorxs lists it at £1,353. 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.
