About this 1.7ct natural pear diamond

This 1.7ct natural pear sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6541629768. Listed at 8 retailers as of October 30, 2026, with prices from £6,742 to £8,781, a £2,039 spread on the same certified stone. GemTrove lists it at £8,781. 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.
