An exceptionally rare 102-carat diamond made auction history Monday.
It’s the first gem of its quality to be sold without a reserve, meaning that it would have been sold regardless of the size of the highest bid.
The flawless diamond sold for $15.7 million.
Cut from a rough diamond discovered in Ontario, Canada, in 2018, it achieved top rankings in each of the “four Cs” -- cut, color, clarity and carat weight.
It has the highest grading for a white diamond, classified as “D color.”
