About this 1.55ct natural cushion diamond

This 1.55ct natural cushion sits in the one-and-a-half to two carat band, graded I 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 5513661456. Listed at 13 retailers as of October 29, 2026, with prices from €3,980 to €7,532, a €3,552 spread on the same certified stone. MOH London lists it at €7,532. 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.
