About this 1ct lab-grown oval diamond

This 1ct lab-grown oval sits in the classic one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG450027318 or 450027318. Listed at 6 retailers as of October 26, 2026, with prices from $1,404 to $2,791, a $1,387 spread on the same certified stone. MOH London lists it at $2,791. 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.
