This 1.35ct natural heart sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 533204937. Listed at 14 retailers as of November 4, 2026, with prices from £3,076 to £6,146, a £3,070 spread on the same certified stone. NZ Jewellers lists it at £6,146. 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.
