About this 1.3ct natural marquise diamond

This 1.3ct natural marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 831624649. Listed at 6 retailers as of October 30, 2026, with prices from $8,694 to $16,352, a $7,658 spread on the same certified stone. NZ Jewellers lists it at $16,352. 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.
