This 1.51ct lab-grown asscher sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG620421805 or 620421805. Listed at 20 retailers as of October 30, 2026, with prices from €279 to €2,658, a €2,379 spread on the same certified stone. Brilliant Earth lists it at €2,658. 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.
