About this 1.51ct natural cushion diamond

This 1.51ct natural cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5463273861. Listed at 8 retailers as of October 31, 2026, with prices from €2,638 to €3,939, a €1,301 spread on the same certified stone. 77 Diamonds lists it at €3,939. 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.
