About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1565268343. Listed at 15 retailers as of November 3, 2026, with prices from $3,232 to $5,649, a $2,417 spread on the same certified stone. Wholesale Diamonds Direct lists it at $5,649. 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.
