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 I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG478113782 or 478113782. Listed at 10 retailers as of November 5, 2026, with prices from $1,515 to $7,475, a $5,960 spread on the same certified stone. MOH London lists it at $7,475. 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.
