About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7568010268. Listed at 13 retailers as of October 31, 2026, with prices from $7,054 to $11,381, a $4,327 spread on the same certified stone. Helzberg Diamonds lists it at $11,381. 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.
