About this 3ct natural heart diamond

This 3ct natural heart sits in the three to five 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 6401719834. Listed at 15 retailers as of November 4, 2026, with prices from £17,036 to £29,144, a £12,109 spread on the same certified stone. MOH London lists it at £29,144. 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.
