This 1.42ct 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 very-good cut grade and certified by IGI LG840634346 or 840634346. Listed at 13 retailers as of November 4, 2026, with prices from $832 to $6,599, a $5,767 spread on the same certified stone. Brilliant Earth lists it at $6,599. 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.
