The read
What the data shows
This was the year's peak, and Geneva made it. The May and June Magnificent Jewels sales carried roughly ninety-one percent of a $202.3 million quarter, up about sixty-eight percent like-for-like, with Christie's alone clearing $103.0 million. Historic colored stones led the top, a Marie-Thérèse Pink diamond realizing $13.98 million. Diamonds still anchored the book at $94.9 million, but the headlines belonged to color: sapphires added $45.4 million, with rubies and emeralds behind them.
