This 0.42ct lab-grown round sits in the sub-half-carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LGF6D93312 or F6D93312. Listed at 2 retailers as of October 28, 2026, with prices from $662 to $1,115, a $453 spread on the same certified stone. 18carati lists it at $1,115. 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.
