About this 1.4ct lab-grown marquise diamond

This 1.4ct 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 very-good cut grade and certified by IGI LG760505183 or 760505183. Listed at a single retailer as of November 4, 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.
