About this 0.71ct lab-grown oval diamond

This 0.71ct lab-grown oval sits in the half to three-quarter carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG499125730 or 499125730. Listed at 12 retailers as of October 29, 2026, with prices from £328 to £2,276, a £1,948 spread on the same certified stone. MOH London lists it at £2,276. 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.
