This 4.55ct lab-grown radiant sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG754595533 or 754595533. Listed at 32 retailers as of October 28, 2026, with prices from $8,923 to $42,663, a $33,740 spread on the same certified stone. With Clarity lists it at $42,663. 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.
