About this 0.51ct natural cushion diamond

This 0.51ct natural cushion sits in the half to three-quarter carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6452191701. Listed at 17 retailers as of November 2, 2026, with prices from $630 to $1,509, a $879 spread on the same certified stone. Flawless Fine Jewelry lists it at $1,509. 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.
