About this 1.5ct lab-grown oval diamond

This 1.5ct 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 LG849626303 or 849626303. Listed at 10 retailers as of October 31, 2026, with prices from £195 to £709, a £514 spread on the same certified stone. Taylor and Hart lists it at £709. 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.
