About this 1.51ct natural cushion diamond

This 1.51ct 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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 3555384405. Listed at 20 retailers as of October 26, 2026, with prices from €3,982 to €8,585, a €4,603 spread on the same certified stone. Wholesale Diamonds Direct lists it at €8,585. 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.
