About this 3.09ct natural heart diamond

This 3.09ct natural heart sits in the three to five carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by HRD 190000099161. Listed at 10 retailers as of November 4, 2026, with prices from $31,841 to $44,454, a $12,612 spread on the same certified stone. NZ Jewellers lists it at $44,454. 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.
