This 1.05ct lab-grown marquise sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG831680175 or 831680175. Listed at 15 retailers as of November 5, 2026, with prices from $342 to $1,771, a $1,428 spread on the same certified stone. MOH London lists it at $1,771. 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.
