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 5 retailers as of October 26, 2026, with prices from $1,483 to $2,839, a $1,355 spread on the same certified stone. MOH London lists it at $2,839. 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.
