About this 1.71ct natural cushion diamond

This 1.71ct natural cushion sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1142688834. Listed at 8 retailers as of October 28, 2026, with prices from £5,104 to £7,001, a £1,896 spread on the same certified stone. Jared lists it at £7,001. 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.
