This 3.4ct lab-grown asscher sits in the three to five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG739505900 or 739505900. Listed at 20 retailers as of October 30, 2026, with prices from $521 to $4,301, a $3,780 spread on the same certified stone. Diamond Wish lists it at $4,301. 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.
