About this 1.02ct natural heart diamond

This 1.02ct natural heart sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2557159016. Listed at 20 retailers as of October 30, 2026, with prices from $2,752 to $7,386, a $4,634 spread on the same certified stone. NZ Jewellers lists it at $7,386. 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.
