This 1.29ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG683590368 or 683590368. Listed at 13 retailers as of October 29, 2026, with prices from €276 to €980, a €704 spread on the same certified stone. MOH London lists it at €980. 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.
