The brooch is ingeniously engineered as a detachable double clip, allowing it to be worn either joined as a brooch or separately as two dress clips, a hallmark of high-quality Art Deco jewellery. The diamonds are notably lively, with some stones exhibiting natural fluorescence consistent with diamonds of the period.

Testing as platinum, the brooch weighs 35.1 grams and remains in excellent condition, with the original double clip mechanism functioning perfectly. A refined and versatile jewel exemplifying the precision, symmetry, and elegance of French Art Deco design.
