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 standard cut grade stated by the retailer rather than the lab and certified by GIA 7543155345. Listed at 8 retailers as of November 2, 2026, with prices from $11,528 to $20,907, a $9,379 spread on the same certified stone. NZ Jewellers lists it at $20,907. 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.
