About this 3.03ct natural heart diamond

This 3.03ct natural heart sits in the three to five carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 28 retailers as of November 4, 2026, with prices from $31,316 to $53,272, a $21,956 spread on the same certified stone. MOH London lists it at $53,272. 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.
