About this 1.21ct natural heart diamond

This 1.21ct 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 and certified by IGI 726522384. Listed at 17 retailers as of November 5, 2026, with prices from £2,305 to £5,634, a £3,329 spread on the same certified stone. NZ Jewellers lists it at £5,634. 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.
