This 0.73ct lab-grown marquise sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG816662424 or 816662424. Listed at 22 retailers as of October 27, 2026, with prices from $321 to $3,099, a $2,779 spread on the same certified stone. Diamond Exchange Canada lists it at $3,099. 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.
