About this 3.09ct natural heart diamond

This 3.09ct natural heart sits in the three to five carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1547678167. Listed at 12 retailers as of November 4, 2026, with prices from £13,322 to £20,884, a £7,562 spread on the same certified stone. MOH London lists it at £20,884. 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.
