About this 1.01ct natural heart diamond

This 1.01ct natural heart sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1558772551. Listed at 16 retailers as of October 30, 2026, with prices from $2,245 to $6,009, a $3,764 spread on the same certified stone. NZ Jewellers lists it at $6,009. 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.
