About this 1.91ct natural marquise diamond

This 1.91ct natural marquise sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2235868766. Listed at 2 retailers as of October 31, 2026, with prices from $15,359 to $20,023, a $4,664 spread on the same certified stone. 77 Diamonds lists it at $20,023. 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.
