About this 1.9ct natural heart diamond

This 1.9ct natural heart sits in the one-and-a-half to two carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2488009909. Listed at 20 retailers as of November 4, 2026, with prices from $31,858 to $51,717, a $19,859 spread on the same certified stone. MOH London lists it at $51,717. 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.
