This 1.25ct 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 LG830620131 or 830620131. Listed at 16 retailers as of October 30, 2026, with prices from £302 to £2,470, a £2,168 spread on the same certified stone. Brilliant Earth lists it at £2,470. 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.
