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 SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6561166470. Listed at 4 retailers as of November 4, 2026, with prices from $18,071 to $29,385, a $11,314 spread on the same certified stone. MOH London lists it at $29,385. 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.
