About this 1.52ct natural marquise diamond

This 1.52ct natural marquise sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 3535469537. Listed at 3 retailers as of October 30, 2026, with prices from $16,729 to $20,463, a $3,734 spread on the same certified stone. 77 Diamonds lists it at $20,463. 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.
