About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1246075731. Listed at 17 retailers as of October 31, 2026, with prices from $4,639 to $8,315, a $3,675 spread on the same certified stone. Helzberg Diamonds lists it at $8,315. 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.
