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 G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG783615285 or 783615285. Listed at 20 retailers as of November 3, 2026, with prices from £158 to £807, a £650 spread on the same certified stone. Brilliant Earth lists it at £807. 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.
