About this 3.15ct lab-grown marquise diamond

This 3.15ct lab-grown marquise sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG695505158 or 695505158. Listed at 3 retailers as of October 30, 2026, with prices from $4,889 to $11,350, a $6,461 spread on the same certified stone. Brilliant Earth lists it at $11,350. 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.
