About this 1.3ct lab-grown oval diamond

This 1.3ct lab-grown oval sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG544271341 or 544271341. Listed at 16 retailers as of October 26, 2026, with prices from £158 to £824, a £666 spread on the same certified stone. MOH London lists it at £824. 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.
