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 VS2 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2526970401. Listed at 19 retailers as of October 30, 2026, with prices from $5,558 to $12,051, a $6,493 spread on the same certified stone. NZ Jewellers lists it at $12,051. 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.
