About this 0.45ct lab-grown oval diamond

This 0.45ct lab-grown oval sits in the sub-half-carat band, graded H colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG577392812 or 577392812. Listed at 18 retailers as of October 29, 2026, with a 639% 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.
