About this 1.51ct natural cushion diamond

This 1.51ct natural cushion sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1569520513. Listed at 13 retailers as of October 27, 2026, with prices from €2,266 to €4,549, a €2,284 spread on the same certified stone. Wholesale Diamonds Direct lists it at €4,549. 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.
