About this 1.6ct natural heart diamond

This 1.6ct natural heart sits in the one-and-a-half to two carat band, graded G 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 7433010152. Listed at 10 retailers as of November 2, 2026, with prices from $18,887 to $31,480, a $12,592 spread on the same certified stone. NZ Jewellers lists it at $31,480. 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.
