I am a creative, strong, versatile and entrepreneurial woman who has a love for design tattooed, which connects me with my most human side.

After making a name for myself, after 20 years as an interior designer; In 2011 I turned my life around and decided to follow my dreams doing what I'm really passionate about, so I launched my own brand of artisanal designer jewelry with the clear objective of revolutionizing the world of goldsmithing through new colors, shine and metal texture.

I found my inspiration in the beauty that exists in nature, since I was a child I discovered a fascination for bugs, their shapes, their whimsical colors and in this way I began to collect them. It is from this passion that the BEE emerges as the representative icon of the Regina Castillo brand, a symbol that reflects our hard-working essence, our community and passion.

The pieces we produce are unique and collectible, most of them are made of .925 silver with pyrite inlays and pendants of faceted stones and crystals and carved by Mexican artisans with ancient techniques, in a 100% artisanal way.
All of the above is present in all our collections since it represents what I am and what I want to transmit to all women using our labor and national resources. With the passage of time I have perfected the quality and technique of my pieces, I specialized in agglutinating the marquise to later give it the gold, pink and blue silver plating, all of them based on the pavé technique that distinguishes me so much.

Currently our production processes are becoming more environmentally friendly.
I have collaborated with renowned artists such as Daniel Espinosa, Abel Lopez, Fernanda Espíritu, Alejandro Carlín, Sandra Weil, Carlos Pineda, Benito Santos, Susana Rodriguez, Sara Galindo, Dennise Kuri, Cristina Obregón, Daniela Cassab and Veronica Díaz.

In 2019, the Fashion Group Mexico Association awarded me the award for "Best Jewelry of the Year" and some time later, "Quien" magazine awarded me for my career as one of the 31 Mexican women who have generated actions of change in the fight for social well-being, in my case, focused on women.

Committed to my brand and the world in which I live, I have participated in different social projects. At the national level, I have designed collections in favor of the Duerme Tranquilo Foundation, the Rebeca De Alba Foundation and charity bazaars such as: Origen and Gilberto.
At the international level, my work LATITUD 29° is in competition and is exhibited at the Latin American Biennial of Contemporary Jewelry and my work Renacer 11, which is part of the Danisova project, to which I was invited by the National Museum of Decorative Arts of Madrid, to reinterpret an emblematic piece from the last century that reflects and revives my evolution.
