About this 3ct natural heart diamond

This 3ct natural heart sits in the three to five carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6475800063. Listed at 10 retailers as of November 4, 2026, with prices from £10,724 to £16,461, a £5,737 spread on the same certified stone. MOH London lists it at £16,461. 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.
