About this 1ct natural heart diamond

This 1ct natural heart sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1547166148. Listed at 26 retailers as of October 30, 2026, with prices from $2,178 to $5,748, a $3,570 spread on the same certified stone. NZ Jewellers lists it at $5,748. 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.
