About this 5.01ct lab-grown marquise diamond

This 5.01ct lab-grown marquise sits in the over five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG837637255 or 837637255. Listed at 6 retailers as of October 30, 2026, with prices from £5,027 to £19,122, a £14,095 spread on the same certified stone. Taylor and Hart lists it at £19,122. 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.
