About this 2.5ct natural cushion diamond

This 2.5ct natural cushion sits in the two to three carat band, graded I 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 1345325048. Listed at 20 retailers as of November 1, 2026, with prices from $16,295 to $28,936, a $12,641 spread on the same certified stone. MOH London lists it at $28,936. 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.
