About this 0.78ct natural cushion diamond

This 0.78ct natural cushion sits in the just-under-one-carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6531109730. Listed at 9 retailers as of October 28, 2026, with prices from $1,578 to $3,078, a $1,500 spread on the same certified stone. Flawless Fine Jewelry lists it at $3,078. 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.
