About this 4ct lab-grown marquise diamond

This 4ct lab-grown marquise sits in the three to five carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG849659678 or 849659678. Listed at 14 retailers as of November 1, 2026, with prices from £387 to £1,602, a £1,216 spread on the same certified stone. Brilliance lists it at £1,602. 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.
