About this 1.56ct natural heart diamond

This 1.56ct natural heart sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6511583775. Listed at 11 retailers as of November 4, 2026, with prices from $24,048 to $36,912, a $12,864 spread on the same certified stone. MOH London lists it at $36,912. 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.
