This 1.02ct lab-grown radiant sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG658492572 or 658492572. Listed at 22 retailers as of October 27, 2026, with prices from $274 to $2,410, a $2,136 spread on the same certified stone. Brilliant Earth lists it at $2,410. 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.
