About this 1ct lab-grown oval diamond

This 1ct lab-grown oval sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG440011002 or 440011002. Listed at 11 retailers as of October 29, 2026, with prices from $580 to $3,932, a $3,352 spread on the same certified stone. MOH London lists it at $3,932. 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.
