This 0.51ct natural round sits in the half to three-quarter carat band, graded K colour (faint-tinted) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by GIA 1565377504. Listed at 18 retailers as of November 4, 2026, with prices from £227 to £1,194, a £967 spread on the same certified stone. NZ Jewellers lists it at £1,194. 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.
