About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5241098369. Listed at 14 retailers as of November 4, 2026, with prices from $6,401 to $11,351, a $4,950 spread on the same certified stone. Wholesale Diamonds Direct lists it at $11,351. 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.
