This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 737595032. Listed at 12 retailers as of October 30, 2026, with prices from $3,027 to $7,066, a $4,038 spread on the same certified stone. NZ Jewellers lists it at $7,066. 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.
