About this 0.81ct natural heart diamond

This 0.81ct natural heart sits in the just-under-one-carat band, graded F 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 2546078774. Listed at 4 retailers as of November 2, 2026, with prices from $1,936 to $3,136, a $1,200 spread on the same certified stone. MOH London lists it at $3,136. 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.
