This 1.38ct 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 LG840629943 or 840629943. Listed at 15 retailers as of October 30, 2026, with prices from £332 to £2,702, a £2,370 spread on the same certified stone. Brilliant Earth lists it at £2,702. 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.
