About this 1.27ct lab-grown round diamond

This 1.27ct lab-grown round sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG775628341 or 775628341. Listed at 16 retailers as of October 25, 2026, with prices from £119 to £788, a £669 spread on the same certified stone. Reve Diamonds lists it at £788. 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.
