This 0.91ct lab-grown round sits in the just-under-one-carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG22048509 or 22048509. Listed at 2 retailers as of October 30, 2026, with prices from $362 to $663, a $302 spread on the same certified stone. Loose Grown Diamond lists it at $663. 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.
