About this 3.06ct natural heart diamond

This 3.06ct natural heart sits in the three to five carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by HRD 210000166396. Listed at 10 retailers as of November 3, 2026, with prices from $17,468 to $28,427, a $10,959 spread on the same certified stone. NZ Jewellers lists it at $28,427. 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.
