About this 0.59ct natural heart diamond

This 0.59ct natural heart sits in the half to three-quarter carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6395091683. Listed at 5 retailers as of November 5, 2026, with prices from £367 to £732, a £366 spread on the same certified stone. MOH London lists it at £732. 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.
