About this 1.03ct lab-grown cushion diamond

This 1.03ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6511708236. Listed at 22 retailers as of November 3, 2026, with prices from £490 to £2,519, a £2,029 spread on the same certified stone. MOH London lists it at £2,519. 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.
