About this 1ct natural heart diamond

This 1ct natural heart sits in the classic one-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 6445465396. Listed at 16 retailers as of November 4, 2026, with prices from £1,417 to £3,026, a £1,609 spread on the same certified stone. MOH London lists it at £3,026. 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.
