About this 6.03ct natural heart diamond

This 6.03ct natural heart sits in the over 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 1232443783. Listed at 3 retailers as of November 1, 2026, with prices from €152,352 to €239,742, a €87,390 spread on the same certified stone. MOH London lists it at €239,742. 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.
