About this 1.21ct natural cushion diamond

This 1.21ct natural cushion sits in the classic one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2566257437. Listed at 3 retailers as of October 30, 2026, with prices from £6,406 to £8,499, a £2,093 spread on the same certified stone. B2C Jewels lists it at £8,499. 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.
