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 717509790. Listed at 7 retailers as of October 30, 2026, with prices from $2,976 to $5,509, a $2,533 spread on the same certified stone. NZ Jewellers lists it at $5,509. 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.
