About this 0.91ct natural heart diamond

This 0.91ct 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 7538052130. Listed at 9 retailers as of October 31, 2026, with prices from $1,877 to $3,086, a $1,208 spread on the same certified stone. 77 Diamonds lists it at $3,086. 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.
