About this 3ct natural heart diamond

This 3ct natural heart sits in the three to five carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2447309231. Listed at 5 retailers as of November 6, 2026, with prices from £19,119 to £23,943, a £4,824 spread on the same certified stone. 77 Diamonds lists it at £23,943. 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.
