About this 1.31ct natural heart diamond

This 1.31ct natural heart sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6545175902. Listed at 4 retailers as of November 6, 2026, with prices from $3,482 to $4,711, a $1,230 spread on the same certified stone. GemTrove lists it at $4,711. 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.
