About this 1.8ct natural oval diamond

This 1.8ct natural oval sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 9 retailers, with prices from $8,043 to $14,956 at NZ Jewellers, a $6,913 spread on the same certified stone. SI-grade stones are eye-clean roughly 60 to 70% of the time at this carat range. Check the inclusion plot on the cert and ask the retailer for high-resolution video before buying.
