About this 1.82ct lab-grown oval diamond

This 1.82ct lab-grown oval sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG512222793 or 512222793. Listed at 12 retailers as of October 25, 2026, with prices from £178 to £839, a £660 spread on the same certified stone. MOH London lists it at £839. 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.
