About this 0.31ct natural heart diamond

This 0.31ct natural heart sits in the sub-half-carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6535443249. Listed at 11 retailers as of November 1, 2026, with prices from £291 to £671, a £380 spread on the same certified stone. MOH London lists it at £671. 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.
