Spinelli Kilcollin Embraces its Dark Side with Black Gold
The brand debuted a new custom alloy at Bergdorf Goodman this month.

New York—Spinelli Kilcollin has become synonymous with an easy, everyday elegance courtesy of its mixed metal interconnected ring stacks, and now its legion of devotees has a new metal with which to play.
Designers Yves Spinelli and Dwyer Kilcollin spent a year and a half customizing a new alloy, dubbed “Black Gold,” with their longtime jeweler Rogelio Ortega and metalsmith Elias Ruiz.
They debuted the new Black Gold collection, consisting of their signature ring styles, at their newest retail partner, Bergdorf Goodman, earlier this month.
The black gold alloy the brand has formulated acts as an alternative to rhodium-plated gold, providing a similar dark-gray hue but without worry of fading over time.
“Black rhodium’s dark façade plays such an important part in our collection and is a favorite of our customers,” Spinelli said. “After a lot of hard work, we are proud and excited to introduce Black Gold to them and the industry at large.”
The brand has incorporated rhodium plating in its ring stacks since its launch in 2010.
Every Black Gold ring, which is created by mixing yellow gold and palladium, is about 20 percent heavier than its yellow, rose or white gold counterparts, lending every stack a more substantial, weighty feel.
The black gold range retails between $4,000 and $10,000 and is currently available at Bergdorf Goodman, SpinelliKilcollin.com, and forthcoming at other retail partners.
