This 5.12ct lab-grown oval sits in the over five carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1465398287. Listed at 4 retailers as of October 28, 2026, with prices from $5,457 to $6,550, a $1,093 spread on the same certified stone. Zales lists it at $6,550. 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.
