About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6565542432. Listed at 12 retailers as of October 27, 2026, with prices from $7,651 to $13,974, a $6,323 spread on the same certified stone. Wholesale Diamonds Direct lists it at $13,974. 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.
