About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded J 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 6461791663. Listed at 16 retailers as of November 5, 2026, with prices from €2,101 to €5,036, a €2,935 spread on the same certified stone. NZ Jewellers lists it at €5,036. 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.
