About this 0.81ct natural oval diamond

This 0.81ct natural oval sits in the just-under-one-carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6545603517. Listed at 5 retailers as of November 4, 2026, with prices from £608 to £979, a £371 spread on the same certified stone. Cape Diamonds lists it at £979. 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.
