About this 0.64ct natural heart diamond

This 0.64ct natural heart sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6532516722. Listed at 10 retailers as of November 1, 2026, with prices from £328 to £931, a £604 spread on the same certified stone. Do Amore Diamonds lists it at £931. 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.
