About this 3.21ct lab-grown heart diamond

This 3.21ct lab-grown heart sits in the three to five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included) and certified by GIA. Listed at a single retailer as of November 1, 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.
