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 SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7326428705. Listed at 10 retailers as of November 2, 2026, with prices from £1,118 to £2,649, a £1,531 spread on the same certified stone. MOH London lists it at £2,649. 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.
