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 VS2 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6432609426. Listed at 17 retailers as of November 1, 2026, with prices from £8,549 to £14,721, a £6,172 spread on the same certified stone. NZ Jewellers lists it at £14,721. 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.
