About this 1.64ct lab-grown oval diamond

This 1.64ct lab-grown oval sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG598306846 or 598306846. Listed at 6 retailers as of October 26, 2026, with prices from £299 to £904, a £606 spread on the same certified stone. MOH London lists it at £904. 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.
