GIA Natural Fancy Color Diamond En Tremblant Brooch

Untreated Fancy Color Diamond En Tremblant Brooch in Platinum

An extraordinary statement of refined artistry and rarity, this GIA-certified brooch features a dazzling ensemble of 67 untreated natural diamonds, all meticulously set in platinum and 18K gold. This includes 30 fancy-cut natural fancy color diamonds totaling approximately 3.5 carats, and 37 round brilliant-cut white diamonds totaling approximately 2.6 carats, for a combined diamond weight of approximately 6.1 carats. Each stone boasts VS clarity and E–F color, representing a remarkable standard of gemological excellence.

Designed in the coveted en tremblant style — a technique that allows the gem-set elements to tremble with subtle motion — this brooch evokes the timeless charm of antique high jewelry while standing as a singular modern treasure.

Each diamond, in its natural, untreated state, reveals a spectrum of color and brilliance rarely encountered on the market today. Reserved for the most discerning collectors, this brooch exemplifies exquisite craftsmanship, historical technique, and artistic vision, uniting precious metals with extraordinary stones in a truly exceptional creation.

The Art of En Tremblant

Originally developed in the 18th century and refined during the Belle Époque, the en tremblant setting technique was used in the finest high jewelry to simulate the delicate motion of natural forms — such as fluttering leaves or trembling petals. Ingeniously engineered with hidden springs or fine hinges, this brooch features gem-set elements that gently quiver with movement, enhancing the brilliance and liveliness of each diamond. The result is a dynamic, almost lifelike quality that elevates the piece from ornament to kinetic art — a hallmark of truly exceptional craftsmanship.
