This 1.51ct lab-grown asscher sits in the one-and-a-half to two carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG812621487 or 812621487. Listed at 22 retailers as of October 28, 2026, with prices from $287 to $2,850, a $2,563 spread on the same certified stone. Brilliant Earth lists it at $2,850. 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.
