About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7556434354. Listed at 19 retailers as of November 3, 2026, with prices from $3,371 to $10,449, a $7,078 spread on the same certified stone. NZ Jewellers lists it at $10,449. 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.
