About this 0.54ct natural cushion diamond

This 0.54ct natural cushion sits in the half to three-quarter carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1555415386. Listed at 2 retailers as of November 2, 2026, with prices from $820 to $1,148, a $329 spread on the same certified stone. 77 Diamonds lists it at $1,148. 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.
