This 1.51ct natural round sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 743523994. Listed at 21 retailers as of November 5, 2026, with prices from $5,587 to $12,771, a $7,184 spread on the same certified stone. NZ Jewellers lists it at $12,771.
