This 1.51ct natural round sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by GIA 6481921061. Listed at 19 retailers as of November 4, 2026, with prices from $10,059 to $22,576, a $12,517 spread on the same certified stone. Diamond Quarter lists it at $22,576.
