This 3.05ct lab-grown marquise sits in the three to five carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG823681075 or 823681075. Listed at 3 retailers as of October 25, 2026, with prices from $3,083 to $8,996, a $5,913 spread on the same certified stone. Brilliant Earth lists it at $8,996. 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.
