About this 1.21ct natural heart diamond

This 1.21ct 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 6562711632. Listed at 9 retailers as of October 27, 2026, with prices from £1,230 to £2,094, a £864 spread on the same certified stone. Wholesale Diamonds Direct lists it at £2,094. 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.
