About this 0.9ct natural cushion diamond

This 0.9ct natural cushion sits in the just-under-one-carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1558517426. Listed at 4 retailers as of October 29, 2026, with prices from $1,758 to $3,507, a $1,749 spread on the same certified stone. MOH London lists it at $3,507. 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.
