About this 3.69ct natural marquise diamond

This 3.69ct natural marquise sits in the three to five 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 1425788327. Listed at 3 retailers as of October 29, 2026, with prices from $64,955 to $78,334, a $13,379 spread on the same certified stone. 77 Diamonds lists it at $78,334. 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.
