About this 20.01ct lab-grown round diamond

This 20.01ct lab-grown round sits in the over five carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG817651466 or 817651466. Listed at 15 retailers as of October 31, 2026, with prices from $9,955 to $40,750, a $30,795 spread on the same certified stone. Taylor and Hart lists it at $40,750. 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.
