About this 3ct natural cushion diamond

This 3ct natural cushion sits in the three to five carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3555372702. Listed at 3 retailers as of October 31, 2026, with prices from €11,112 to €13,285, a €2,173 spread on the same certified stone. Blue Nile lists it at €13,285. 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.
