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 $2,086 to $4,896, a $2,811 spread on the same certified stone. MOH London lists it at $4,896. 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.
