About this 1.01ct lab-grown cushion diamond

This 1.01ct lab-grown cushion sits in the classic one-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG811663986 or 811663986. Listed at 5 retailers as of October 31, 2026, with prices from £256 to £519, a £263 spread on the same certified stone. Taylor and Hart lists it at £519. 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.
