About this 6.51ct lab-grown oval diamond

This 6.51ct lab-grown oval sits in the over five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG722555641 or 722555641. Listed at 16 retailers as of October 29, 2026, with prices from $1,298 to $5,236, a $3,938 spread on the same certified stone. Taylor and Hart lists it at $5,236. 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.
