About this 0.74ct natural heart diamond

This 0.74ct 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 6555076580. Listed at 4 retailers as of November 2, 2026, with prices from £428 to £530, a £102 spread on the same certified stone. 77 Diamonds lists it at £530. 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.
