About this 1.24ct lab-grown asscher diamond

This 1.24ct 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 LG647427160 or 647427160. Listed at 4 retailers as of October 30, 2026, with prices from £374 to £1,967, a £1,593 spread on the same certified stone. Zales lists it at £1,967. 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.
