About this 1.2ct natural heart diamond

This 1.2ct natural heart sits in the classic one-carat band, graded K colour (faint-tinted) and VS2 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6312655043. Listed at 11 retailers as of November 4, 2026, with prices from £1,511 to £3,177, a £1,666 spread on the same certified stone. MOH London lists it at £3,177. 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.
