About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-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 3415140293. Listed at 21 retailers as of October 31, 2026, with prices from €2,629 to €5,722, a €3,093 spread on the same certified stone. MOH London lists it at €5,722. 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.
