About this 0.9ct natural cushion diamond
This 0.9ct natural cushion sits in the just-under-one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5543153205. Listed at 5 retailers as of November 5, 2026, with prices from $565 to $760, a $195 spread on the same certified stone. 77 Diamonds lists it at $760. 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.
