About this 1.23ct lab-grown oval diamond

This 1.23ct lab-grown oval sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG610351809 or 610351809. Listed at 16 retailers as of November 4, 2026, with prices from $237 to $1,499, a $1,262 spread on the same certified stone. Taylor and Hart lists it at $1,499. 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.
