This 1.66ct lab-grown round sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG754510402 or 754510402. Listed at 13 retailers as of November 1, 2026, with prices from €180 to €1,042, a €862 spread on the same certified stone. MOH London lists it at €1,042. 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.
