This 0.51ct lab-grown oval sits in the half to three-quarter carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG407941428 or 407941428. Listed at 13 retailers as of October 29, 2026, with prices from $435 to $2,175, a $1,739 spread on the same certified stone. MOH London lists it at $2,175. 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.
