About this 2.78ct lab-grown heart diamond

This 2.78ct lab-grown heart sits in the two to three carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless) and certified by IGI. Listed at a single retailer as of October 30, 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.
