This 1.57ct lab-grown radiant sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG681504532 or 681504532. Listed at 14 retailers as of October 26, 2026, with prices from €165 to €971, a €806 spread on the same certified stone. MOH London lists it at €971. 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.
