About this 0.4ct natural heart diamond

This 0.4ct 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 7563237987. Listed at 2 retailers as of October 27, 2026, with prices from £225 to £285, a £61 spread on the same certified stone. 77 Diamonds lists it at £285. 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.
