About this 1.37ct lab-grown marquise diamond

This 1.37ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG686507732 or 686507732. Listed at a single retailer as of October 31, 2026. If it later appears at another store, Carat Hunter will surface the price comparison automatically. 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.
