This 0.99ct lab-grown radiant sits in the just-under-one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG615377011 or 615377011. Listed at 16 retailers as of October 29, 2026, with prices from $229 to $1,485, a $1,255 spread on the same certified stone. Flawless Fine Jewelry lists it at $1,485. 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.
