About this 3.51ct natural heart diamond

This 3.51ct 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 1549759784. Listed at 6 retailers as of November 6, 2026, with prices from $54,604 to $98,520, a $43,916 spread on the same certified stone. MOH London lists it at $98,520. 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.
