This 1.53ct natural marquise sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 01-15502427. Listed at 2 retailers as of November 1, 2026, with prices from $6,906 to $10,285, a $3,379 spread on the same certified stone. Diamonds Direct lists it at $10,285. 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.
