About this 0.92ct lab-grown round diamond

This 0.92ct lab-grown round sits in the just-under-one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG22048511 or 22048511. Listed at 2 retailers as of October 30, 2026, with prices from £152 to £330, a £178 spread on the same certified stone. Loose Grown Diamond lists it at £330. 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.
