About this 2.51ct natural heart diamond

This 2.51ct natural heart sits in the two to three 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 6552036750. Listed at 16 retailers as of October 30, 2026, with prices from $10,136 to $19,342, a $9,206 spread on the same certified stone. NZ Jewellers lists it at $19,342. 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.
