About this 0.42ct lab-grown heart diamond

This 0.42ct lab-grown heart sits in the sub-half-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG635408860 or 635408860. Listed at a single retailer as of October 29, 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.
