About this 0.81ct natural heart diamond

This 0.81ct natural heart sits in the just-under-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 7561120011. Listed at 6 retailers as of November 2, 2026, with prices from $1,220 to $1,964, a $744 spread on the same certified stone. GemTrove lists it at $1,964. 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.
