About this 3.07ct natural heart diamond

This 3.07ct natural heart sits in the three to five carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by HRD 190000099165. Listed at 7 retailers as of November 4, 2026, with prices from $16,423 to $26,726, a $10,303 spread on the same certified stone. NZ Jewellers lists it at $26,726. 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.
