About this 3ct natural cushion diamond

This 3ct natural cushion sits in the three to five carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 3555413575. Listed at 2 retailers as of November 5, 2026, with prices from $23,065 to $27,604, a $4,539 spread on the same certified stone. Blue Nile lists it at $27,604. 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.
