About this 1.03ct natural marquise diamond

This 1.03ct natural marquise sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 14988176. Listed at 5 retailers as of November 1, 2026, with prices from $12,935 to $19,461, a $6,526 spread on the same certified stone. MOH London lists it at $19,461. 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.
