About this 1.01ct natural heart diamond

This 1.01ct natural heart sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6431635587. Listed at 17 retailers as of October 29, 2026, with prices from €1,345 to €3,396, a €2,050 spread on the same certified stone. MOH London lists it at €3,396. 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.
