About this 0.81ct natural heart diamond

This 0.81ct natural heart sits in the just-under-one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1517152668. Listed at 2 retailers as of November 2, 2026, with prices from $1,634 to $2,518, a $883 spread on the same certified stone. MOH London lists it at $2,518. 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.
