About this 1.09ct natural heart diamond

This 1.09ct natural heart sits in the classic one-carat band, graded G 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 5191488056. Listed at 12 retailers as of October 30, 2026, with prices from $5,195 to $10,285, a $5,090 spread on the same certified stone. NZ Jewellers lists it at $10,285. 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.
