About this 0.78ct natural marquise diamond

This 0.78ct natural marquise sits in the just-under-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. Listed at 8 retailers as of November 4, 2026, with prices from $1,797 to $5,179, a $3,381 spread on the same certified stone. NZ Jewellers lists it at $5,179. 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.
