This 1.39ct lab-grown asscher sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG842604104 or 842604104. Listed at 15 retailers as of November 1, 2026, with prices from £212 to £2,049, a £1,837 spread on the same certified stone. Brilliant Earth lists it at £2,049. 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.
