About this 2.5ct natural cushion diamond

This 2.5ct natural cushion sits in the two to three carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1543807487. Listed at 4 retailers as of October 28, 2026, with prices from £16,885 to £19,765, a £2,880 spread on the same certified stone. 77 Diamonds lists it at £19,765. 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.
