About this 0.77ct natural heart diamond

This 0.77ct natural heart sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1529449791. Listed at 3 retailers as of November 6, 2026, with prices from $1,470 to $2,174, a $704 spread on the same certified stone. GemTrove lists it at $2,174. 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.
