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 1558328161. Listed at 14 retailers as of November 4, 2026, with prices from $6,473 to $11,630, a $5,156 spread on the same certified stone. Wholesale Diamonds Direct lists it at $11,630. 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.
