This 1.31ct lab-grown asscher sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG840622315 or 840622315. Listed at 21 retailers as of November 4, 2026, with prices from $496 to $4,383, a $3,887 spread on the same certified stone. Brilliant Earth lists it at $4,383. 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.
