About this 1.77ct natural cushion diamond

This 1.77ct natural cushion sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6561073849. Listed at 8 retailers as of November 6, 2026, with prices from £2,814 to £3,729, a £915 spread on the same certified stone. GemTrove lists it at £3,729. 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.
