About this 0.5ct natural marquise diamond

This 0.5ct natural marquise sits in the half to three-quarter carat band, graded G colour (near-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 7558139032. Listed at 7 retailers as of November 4, 2026, with prices from £604 to £965, a £361 spread on the same certified stone. GemTrove lists it at £965. 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.
