About this 0.91ct natural heart diamond

This 0.91ct natural heart sits in the just-under-one-carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5212496659. Listed at 3 retailers as of November 4, 2026, with prices from $1,516 to $2,915, a $1,399 spread on the same certified stone. MOH London lists it at $2,915. 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.
