About this 0.63ct natural heart diamond

This 0.63ct natural heart sits in the half to three-quarter carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7542386902. Listed at 5 retailers as of November 4, 2026, with prices from £360 to £471, a £111 spread on the same certified stone. Blue Nile lists it at £471. 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.
