About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6551987263. Listed at 9 retailers as of October 30, 2026, with prices from $16,806 to $27,141, a $10,335 spread on the same certified stone. NZ Jewellers lists it at $27,141. 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.
