About this 0.91ct natural heart diamond

This 0.91ct natural heart sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2233880400. Listed at 13 retailers as of November 2, 2026, with prices from $4,034 to $10,446, a $6,412 spread on the same certified stone. Moon Ocean lists it at $10,446. 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.
