About this 1.55ct lab-grown oval diamond

This 1.55ct lab-grown oval sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG620416763 or 620416763. Listed at 5 retailers as of October 29, 2026, with prices from £249 to £852, a £602 spread on the same certified stone. MOH London lists it at £852. 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.
