About this 0.61ct natural cushion diamond

This 0.61ct natural cushion sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2151879206. Listed at 8 retailers as of November 1, 2026, with prices from $1,341 to $2,057, a $715 spread on the same certified stone. 77 Diamonds lists it at $2,057. 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.
