About this 1.01ct natural heart diamond

This 1.01ct natural heart sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6411349386. Listed at 18 retailers as of November 3, 2026, with prices from £1,327 to £3,728, a £2,401 spread on the same certified stone. NZ Jewellers lists it at £3,728. 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.
