About this 0.51ct natural cushion diamond

This 0.51ct natural cushion sits in the half to three-quarter carat band, graded H 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 6551074015. Listed at 15 retailers as of November 4, 2026, with prices from $867 to $2,068, a $1,201 spread on the same certified stone. Flawless Fine Jewelry lists it at $2,068. 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.
