This 1.01ct natural oval sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 1558080405. Listed at 10 retailers as of November 2, 2026, with prices from $1,550 to $4,964, a $3,415 spread on the same certified stone. NZ Jewellers lists it at $4,964.
