About this 1.5ct lab-grown radiant diamond

This 1.5ct 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 standard cut grade and certified by IGI LG508122910 or 508122910. Listed at 15 retailers as of October 29, 2026, with prices from €329 to €1,606, a €1,277 spread on the same certified stone. MOH London lists it at €1,606. 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.
