About this 0.99ct lab-grown heart diamond

This 0.99ct lab-grown heart sits in the just-under-one-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG639486176 or 639486176. Listed at a single retailer as of November 2, 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.
