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 SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6452314509. Listed at 5 retailers as of November 4, 2026, with prices from $1,688 to $3,196, a $1,508 spread on the same certified stone. MOH London lists it at $3,196. 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.
