About this 0.52ct lab-grown oval diamond

This 0.52ct lab-grown oval sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG851692061 or 851692061. Listed at 10 retailers as of November 5, 2026, with prices from £63 to £250, a £187 spread on the same certified stone. NZ Jewellers lists it at £250. 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.
