This 1.04ct lab-grown asscher sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG799620150 or 799620150. Listed at 20 retailers as of October 30, 2026, with prices from £183 to £1,269, a £1,086 spread on the same certified stone. Brilliant Earth lists it at £1,269. 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.
