About this 1.5ct natural marquise diamond

This 1.5ct natural marquise sits in the one-and-a-half to two carat band, graded M colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5566040285. Listed at 5 retailers as of November 6, 2026, with prices from $4,300 to $7,180, a $2,879 spread on the same certified stone. Wholesale Diamonds Direct lists it at $7,180. 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.
