About this 0.53ct lab-grown oval diamond

This 0.53ct lab-grown oval sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840620505 or 840620505. Listed at 7 retailers as of October 31, 2026, with prices from £928 to £1,209, a £281 spread on the same certified stone. Brilliant Earth lists it at £1,209. 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.
