This 4.1ct 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 LG754594967 or 754594967. Listed at 31 retailers as of October 30, 2026, with prices from £2,539 to £15,907, a £13,368 spread on the same certified stone. With Clarity lists it at £15,907. 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.
