About this 4.52ct lab-grown oval diamond

This 4.52ct lab-grown oval sits in the three to five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG578351481 or 578351481. Listed at 17 retailers as of October 29, 2026, with prices from $1,437 to $7,878, a $6,441 spread on the same certified stone. Brilliant Earth lists it at $7,878. 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.
