About this 1.52ct lab-grown oval diamond

This 1.52ct lab-grown oval sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG440012863 or 440012863. Listed at 11 retailers as of October 29, 2026, with prices from $1,473 to $8,727, a $7,255 spread on the same certified stone. MOH London lists it at $8,727. 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.
