About this 1.7ct natural cushion diamond

This 1.7ct natural cushion sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless) and certified by GIA 3405238743. Listed at 2 retailers as of November 1, 2026, with prices from £9,694 to £12,045, a £2,351 spread on the same certified stone. Yorxs lists it at £12,045. 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.
