Piece of the Week: A Bulgari Sapphire and Diamond Necklace
Set with a 118-carat unheated Sri Lankan sapphire, it just sold for $3.4 million at Phillips jewelry auction in Hong Kong.

A buyer paid $25.2 million for the “Bulgari Laguna Blu,” an 11.16-carat fancy vivid blue diamond, during “Luxury Week” at Sotheby’s Geneva, held May 12-16.
Then, earlier this week, a Bulgari necklace featuring a 118.35-carat unheated Sri Lankan sapphire went for $3.4 million at Phillips Hong Kong.
The sale price fell at the low end of the piece’s pre-sale estimated range ($3 million to $4.5 million) but was enough to make it the top lot of the jewelry auction, accounting for nearly half of the sale’s total.
According to Phillips, Bulgari created the diamond and sapphire piece for its high jewelry collection in 2004 after acquiring the sapphire.
It remained in a private collection until coming to Phillips for auction this spring.
In a 2023 report, Gübelin Gem Lab gave the gemstone 98 out of 100 Gübelin points, a ranking that designates the stone as “exceptional” in the lab’s terms. The lab graded the sapphire’s color as “Royal Blue” because of its even saturation.
The auction house said it is one of the largest sapphires offered at auction in the past 30 years.
Phillips’ “Jewels & Jadeite” spring auction in Hong Kong totaled $7.5 million. It was sold 93 percent by lot and 91 percent by value.
Full results are available on the Phillips website.
