About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7562693903. Listed at 14 retailers as of November 5, 2026, with prices from $3,328 to $7,671, a $4,343 spread on the same certified stone. NZ Jewellers lists it at $7,671. 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.
