This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6562650119. Listed at 10 retailers as of November 6, 2026, with prices from $5,760 to $10,524, a $4,764 spread on the same certified stone. Wholesale Diamonds Direct lists it at $10,524. 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.
