About this 1.2ct natural heart diamond

This 1.2ct natural heart sits in the classic one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5543146495. Listed at 7 retailers as of October 31, 2026, with prices from $3,589 to $8,846, a $5,256 spread on the same certified stone. NZ Jewellers lists it at $8,846. 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.
