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 LG407950361 or 407950361. Listed at 12 retailers as of October 29, 2026, with prices from $390 to $1,949, a $1,559 spread on the same certified stone. MOH London lists it at $1,949. 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.
