About this 1.2ct natural heart diamond

This 1.2ct natural heart sits in the classic one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6562757729. Listed at 9 retailers as of November 4, 2026, with prices from £1,316 to £2,201, a £886 spread on the same certified stone. Wholesale Diamonds Direct lists it at £2,201. 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.
