About this 1.05ct lab-grown radiant diamond

This 1.05ct lab-grown radiant sits in the classic one-carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG628488175 or 628488175. Listed at 28 retailers as of November 4, 2026, with prices from £133 to £838, a £705 spread on the same certified stone. Reve Diamonds lists it at £838. 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.
