This 1.27ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG612329306 or 612329306. Listed at 6 retailers as of November 1, 2026, with prices from €340 to €1,041, a €701 spread on the same certified stone. MOH London lists it at €1,041. 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.
