About this 0.91ct natural heart diamond

This 0.91ct natural heart sits in the just-under-one-carat band, graded G colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 678553059. Listed at 15 retailers as of October 30, 2026, with prices from £1,303 to £3,826, a £2,522 spread on the same certified stone. NZ Jewellers lists it at £3,826. 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.
