About this 0.9ct lab-grown oval diamond

This 0.9ct lab-grown oval sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG710508809 or 710508809. Listed at 10 retailers as of October 29, 2026, with prices from £122 to £984, a £861 spread on the same certified stone. Do Amore Diamonds lists it at £984. 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.
