About this 0.31ct lab-grown marquise diamond

This 0.31ct lab-grown marquise sits in the sub-half-carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG311880031 or 311880031. Listed at a single retailer as of October 28, 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.
