Designer's Message

Jewellery is a woman’s “indispensable dispensable”.


Of course, we can live without it.

For some, this small stone might look trivial.

Just one of many things with which to decorate a life.


Jewellery has, however, an absolute beauty that grips a woman’s heart,

beyond the reach of logic or rationality.

It imbues life with an air of elegance, grace and luxury.


At the same time, jewellery is a statement of our personality,

speaking about our taste, sense of value and style, far more eloquently than words.


Mastering the art of jewellery is an intellectual play for adults.

After a 20 plus year career, I feel I have finally begun to know its true joy.

I want to offer my jewellery to the tough women of our time

who casually overcome life’s obstacles with a curious mind and strong resolve.


I want them to know and feel jewellery can empower us in a very beautiful way.


With this wish, I wholeheartedly bring another “indispensable dispensable” into the world.
