About this 3.02ct natural heart diamond

This 3.02ct 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 2566435921. Listed at 4 retailers as of November 5, 2026, with prices from £18,587 to £21,973, a £3,386 spread on the same certified stone. Blue Nile lists it at £21,973. 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.
