About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6551636585. Listed at 8 retailers as of November 5, 2026, with prices from $5,255 to $10,275, a $5,020 spread on the same certified stone. NZ Jewellers lists it at $10,275. 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.
