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 SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1545779961. Listed at 17 retailers as of October 30, 2026, with prices from €1,943 to €5,452, a €3,509 spread on the same certified stone. NZ Jewellers lists it at €5,452. 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.
