About this 0.53ct lab-grown round diamond

This 0.53ct lab-grown round sits in the half to three-quarter carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG712532525 or 712532525. Listed at 6 retailers as of November 4, 2026, with prices from £405 to £750, a £345 spread on the same certified stone. Rare Carat lists it at £750. 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.
