About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded J 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 6562520123. Listed at 15 retailers as of October 31, 2026, with prices from $1,985 to $3,866, a $1,881 spread on the same certified stone. Helzberg Diamonds lists it at $3,866. 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.
