This 0.75ct lab-grown radiant sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG738511964 or 738511964. Listed at 20 retailers as of November 4, 2026, with prices from £229 to £1,142, a £914 spread on the same certified stone. Reve Diamonds lists it at £1,142. 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.
