This 4.23ct lab-grown oval 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 LG534263029 or 534263029. Listed at 18 retailers as of October 31, 2026, with prices from $935 to $8,304, a $7,369 spread on the same certified stone. Do Amore Diamonds lists it at $8,304. 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.
