This 1.7ct natural heart sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 737519484. Listed at 9 retailers as of November 5, 2026, with prices from £5,794 to £9,690, a £3,896 spread on the same certified stone. NZ Jewellers lists it at £9,690. 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.
