About this 1.03ct natural heart diamond

This 1.03ct natural heart sits in the classic one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2181013286. Listed at 6 retailers as of November 1, 2026, with prices from $4,910 to $9,809, a $4,899 spread on the same certified stone. MOH London lists it at $9,809. 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.
