About this 0.75ct natural cushion diamond

This 0.75ct natural cushion sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7551002275. Listed at 6 retailers as of October 30, 2026, with prices from £502 to £633, a £131 spread on the same certified stone. Blue Nile lists it at £633. 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.
