About this 1.09ct lab-grown oval diamond

This 1.09ct lab-grown oval sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG436074457 or 436074457. Listed at 12 retailers as of November 5, 2026, with prices from $872 to $4,252, a $3,379 spread on the same certified stone. MOH London lists it at $4,252. 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.
