About this 1ct natural heart diamond

This 1ct natural heart sits in the classic one-carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1232694430. Listed at 10 retailers as of November 2, 2026, with prices from £1,404 to £3,278, a £1,874 spread on the same certified stone. NZ Jewellers lists it at £3,278. 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.
