About this 1.2ct natural heart diamond

This 1.2ct natural heart sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2437910992. Listed at 18 retailers as of November 2, 2026, with prices from £2,710 to £5,596, a £2,887 spread on the same certified stone. MOH London lists it at £5,596. 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.
