About this 0.97ct lab-grown marquise diamond

This 0.97ct lab-grown marquise sits in the just-under-one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included) and certified by IGI LG617401982 or 617401982. Listed at a single retailer as of November 2, 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.
