About this 1.58ct lab-grown oval diamond

This 1.58ct lab-grown oval sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG549282437 or 549282437. Listed at 3 retailers as of November 1, 2026, with prices from $399 to $1,062, a $663 spread on the same certified stone. MOH London lists it at $1,062. 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.
