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. Listed at 3 retailers as of November 5, 2026, with prices from $3,947 to $4,917, a $970 spread on the same certified stone. Blue Nile lists it at $4,917. 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.
