About this 3.16ct natural heart diamond

This 3.16ct natural heart sits in the three to five 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 1545927634. Listed at 17 retailers as of November 4, 2026, with prices from $42,138 to $80,716, a $38,578 spread on the same certified stone. MOH London lists it at $80,716. 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.
