About this 1ct lab-grown cushion diamond

This 1ct lab-grown cushion sits in the classic one-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG812608540 or 812608540. Listed at 6 retailers as of October 29, 2026, with prices from €298 to €596, a €298 spread on the same certified stone. Taylor and Hart lists it at €596. 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.
