This 1.8ct natural oval sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 805628310. Listed at 13 retailers as of November 5, 2026, with prices from £3,173 to £6,427, a £3,254 spread on the same certified stone. NZ Jewellers lists it at £6,427. 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.
