About this 0.51ct natural emerald diamond

This 0.51ct natural emerald sits in the half to three-quarter carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2516592642. Listed at 6 retailers as of November 6, 2026, with prices from $390 to $533, a $143 spread on the same certified stone. 77 Diamonds lists it at $533. 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.
