About this 4.07ct lab-grown marquise diamond

This 4.07ct lab-grown marquise sits in the three to five 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 6531726997. Listed at 21 retailers as of October 28, 2026, with prices from £10,284 to £30,088, a £19,804 spread on the same certified stone. Brilliance lists it at £30,088. 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.
