About this 0.46ct lab-grown heart diamond

This 0.46ct lab-grown heart sits in the sub-half-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG847619138 or 847619138. Listed at 7 retailers as of October 27, 2026, with a 206% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
