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 October 30, 2026, with prices from $423 to $3,430, a $3,007 spread on the same certified stone. Brilliant Earth lists it at $3,430. 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.
