About this 3.7ct natural marquise diamond

This 3.7ct natural marquise 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 6505266839. Listed at 13 retailers as of October 31, 2026, with prices from $72,265 to $99,499, a $27,234 spread on the same certified stone. Yorxs lists it at $99,499. 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.
