About this 0.5ct lab-grown oval diamond

This 0.5ct lab-grown oval sits in the half to three-quarter carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG436073715 or 436073715. Listed at 11 retailers as of October 25, 2026, with prices from £224 to £1,113, a £889 spread on the same certified stone. MOH London lists it at £1,113. 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.
