About this 1.03ct natural heart diamond

This 1.03ct natural heart sits in the classic one-carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 803629159. Listed at 8 retailers as of November 4, 2026, with prices from £1,093 to £3,173, a £2,080 spread on the same certified stone. NZ Jewellers lists it at £3,173. 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.
