About this 3ct lab-grown marquise diamond

This 3ct lab-grown marquise sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG754563785 or 754563785. Listed at 31 retailers as of October 31, 2026, with prices from £2,344 to £17,830, a £15,486 spread on the same certified stone. Do Amore Diamonds lists it at £17,830. 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.
