About this 1.2ct natural heart diamond

This 1.2ct natural heart sits in the classic one-carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 803652669. Listed at 9 retailers as of October 30, 2026, with prices from €3,232 to €6,144, a €2,912 spread on the same certified stone. MOH London lists it at €6,144. 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.
