About this 1.7ct natural cushion diamond

This 1.7ct natural cushion sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1553664583. Listed at 19 retailers as of October 28, 2026, with prices from €4,565 to €10,055, a €5,490 spread on the same certified stone. Queensmith lists it at €10,055. 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.
