About this 1.91ct natural heart diamond

This 1.91ct natural heart sits in the one-and-a-half to two carat band, graded F 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 2225107021. Listed at 11 retailers as of November 5, 2026, with prices from $31,491 to $46,775, a $15,285 spread on the same certified stone. SJ Gems lists it at $46,775. 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.
