About this 0.5ct lab-grown oval diamond

This 0.5ct lab-grown oval sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407950365 or 407950365. Listed at 11 retailers as of October 29, 2026, with prices from £202 to £1,005, a £803 spread on the same certified stone. MOH London lists it at £1,005. 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.
