About this 1.81ct natural cushion diamond

This 1.81ct 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 1567385390. Listed at 6 retailers as of November 1, 2026, with prices from £4,870 to £7,460, a £2,590 spread on the same certified stone. MOH London lists it at £7,460. 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.
