About this 1.05ct lab-grown cushion diamond

This 1.05ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG689562206 or 689562206. Listed at 17 retailers as of November 4, 2026, with prices from £137 to £806, a £668 spread on the same certified stone. Reve Diamonds lists it at £806. 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.
