This 5.1ct lab-grown radiant sits in the over five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG762544650 or 762544650. Listed at 14 retailers as of October 31, 2026, with prices from $11,244 to $47,304, a $36,061 spread on the same certified stone. Taylor and Hart lists it at $47,304. 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.
