This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 648418609. Listed at 19 retailers as of November 5, 2026, with prices from £1,913 to £4,660, a £2,747 spread on the same certified stone. NZ Jewellers lists it at £4,660. 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.
