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 VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5546303370. Listed at 6 retailers as of November 6, 2026, with prices from £490 to £629, a £138 spread on the same certified stone. 77 Diamonds lists it at £629. 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.
