The same year, Emily was invited to Tokyo by a friend who had become cultural counsellor at the British Embassy. She had surprised Emily by including her on the list of the British delegation present at the inauguration of the Shinto Meiji Shrine.

Finding protocol speeches boring, Emily took the liberty of leaving the official stands. After some walking time, she entered into the imperial garden. Imagined by the emperor for his wife, this green setting was dedicated to Amaterasu: the sun goddess.

For several long minutes, the garden was caressed by the rays of bright sun. Magnified by the golden light, its majestic triangular shape jumped to Emily's eyes. She felt in total symbiosis with the sacred and peaceful atmosphere of the place. 

Once back in London, Emily remained seized by the harmony she had experienced in this Japanese cultural place. Highly inspired, she grabbed her pencils and drew a stylized triangle. The shape of the triangle symbolized the sunny imperial garden. Its gold/white/ochre colors were reminiscent of those of the august deity who illuminated the sky of the land of the rising sun.

From this stylized triangle, Emily developed a series of minimalist jewels. This diamond paved pyramidal pendant was the iconic piece of this collection, and triumphed at the 1925 International Exhibition of Decorative Arts. The bold lines of these little marvels harmoniously matched the silhouette of a resolutely modern woman. In this way, Emily made a personal contribution to the emancipation of women in the 1930s.
