About this 1.23ct natural heart diamond

This 1.23ct natural heart sits in the classic one-carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 17180547. Listed at 13 retailers as of November 4, 2026, with prices from $8,109 to $15,554, a $7,444 spread on the same certified stone. NZ Jewellers lists it at $15,554. 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.
