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 1513650883. Listed at 6 retailers as of November 2, 2026, with prices from $1,105 to $1,878, a $773 spread on the same certified stone. MOH London lists it at $1,878. 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.
