About this 1.24ct natural heart diamond

This 1.24ct natural heart sits in the classic one-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 1303811341. Listed at 10 retailers as of November 4, 2026, with prices from £1,071 to £2,513, a £1,443 spread on the same certified stone. MOH London lists it at £2,513. 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.
