About this 0.51ct natural marquise diamond
This 0.51ct natural marquise sits in the half to three-quarter carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5231904490. Listed at 15 retailers as of October 30, 2026, with prices from £581 to £1,977, a £1,396 spread on the same certified stone. NZ Jewellers lists it at £1,977. 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.
