About this 0.42ct natural heart diamond

This 0.42ct natural heart sits in the sub-half-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 6422297993. Listed at 10 retailers as of October 31, 2026, with prices from £453 to £906, a £453 spread on the same certified stone. MOH London lists it at £906. 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.
