About this 0.46ct natural heart diamond

This 0.46ct natural heart sits in the sub-half-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2564293076. Listed at 2 retailers as of November 6, 2026, with prices from £249 to £332, a £83 spread on the same certified stone. 77 Diamonds lists it at £332. 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.
