This 0.75ct lab-grown radiant sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG539226792 or 539226792. Listed at 16 retailers as of October 26, 2026, with prices from £104 to £608, a £503 spread on the same certified stone. MOH London lists it at £608. 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.
