About this 0.51ct natural marquise diamond

This 0.51ct natural marquise sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5476882631. Listed at 20 retailers as of October 30, 2026, with prices from $1,950 to $5,330, a $3,380 spread on the same certified stone. NZ Jewellers lists it at $5,330. 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.
