About this 1.5ct natural marquise diamond

This 1.5ct natural marquise sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1567329727. Listed at 13 retailers as of November 2, 2026, with prices from $6,240 to $10,243, a $4,003 spread on the same certified stone. Helzberg Diamonds lists it at $10,243. 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.
