About this 1.21ct natural heart diamond

This 1.21ct natural heart sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2243080054. Listed at 16 retailers as of November 5, 2026, with prices from $2,362 to $6,848, a $4,486 spread on the same certified stone. NZ Jewellers lists it at $6,848. 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.
