About this 4.58ct lab-grown radiant diamond

This 4.58ct 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 LG722516423 or 722516423. Listed at 21 retailers as of October 29, 2026, with prices from £4,666 to £19,426, a £14,760 spread on the same certified stone. Michael Trio lists it at £19,426. 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.
