This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 768618013. Listed at 6 retailers as of October 30, 2026, with prices from £2,171 to £3,959, a £1,787 spread on the same certified stone. NZ Jewellers lists it at £3,959. 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.
