About this 1.48ct lab-grown oval diamond

This 1.48ct lab-grown oval 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 LG836607833 or 836607833. Listed at 16 retailers as of October 30, 2026, with prices from £204 to £1,829, a £1,624 spread on the same certified stone. Brilliant Earth lists it at £1,829. 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.
