About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2496993987. Listed at 6 retailers as of October 30, 2026, with prices from €2,818 to €5,308, a €2,490 spread on the same certified stone. MOH London lists it at €5,308. 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.
