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 £13,042 to £19,373, a £6,330 spread on the same certified stone. SJ Gems lists it at £19,373. 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.
