This 1.43ct natural heart sits in the one-and-a-quarter to one-and-a-half carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 768623508. Listed at 11 retailers as of November 5, 2026, with prices from £1,532 to £3,921, a £2,389 spread on the same certified stone. NZ Jewellers lists it at £3,921. 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.
