About Us

The word "tremendum" comes from the Latin word "mysterium tremendum," which means "a great or deep mystery." This is what a person feels when they see something or go somewhere that makes them feel awe and a desire to return.

Tremendum's jewelry design is intended to deliver contemporary products based on Indonesian cultural roots and to uncover a new beauty in Asian workmanship.

Tremendum is a tribute to Indonesia's rich cultural diversity and the artisanal talents of the country's native jewelers. Not only is it important to respect this ancient culture, but doing so will help to preserve the civilization as a whole.

Who is behind Tremendum?

Rockologist is a brand that consistently creates bespoke hand-fabricated jewelry. They established the brand with a noble purpose: to save this kind of jewelry from the domination of mass-produced ones.

Fani Atmanti is an Indonesian architect who has a deep admiration for the culture of Indonesia and the world. Having visited several tribes in Indonesia, she expanded her inspiration to create the Tremendum collection’s design.

And let us tell you more about Tremendum...

Traditional Artwork for Indigenous People’s Education

For every order you've made, we will set aside some profit to be donated in your name to Sokola Institute for indigenous people’s education throughout Indonesia.

A suitable education will hopefully ensure the preservation of local wisdom, nature, cultural richness, and the fulfillment of indigenous people’s rights.

All collections are distinctively designed by Fani Atmanti —

All Tremendum’s collections are specially designed by Fani Atmanti and inspired by unique points from each tribe and culture that she experienced by herself on her journey.

She then draws every detail that mesmerizes her and transforms it into statement-ring form, all done in order to obtain distinctive yet wearable jewelry collections.

Hand-fabricated: an ancient jewelry crafting method on the verge of extinction  —

Each piece of jewelry in the Tremendum collection is Hand-fabricated without the use of molds, wax, or casting. Before the pieces of jewelry are soldered together, molten metal ingots are pressed, bent, shaped, or pulled into different shapes.

In one of Yogyakarta's historic cities, the former capital of the Mataram Kingdom, which is recognized for its extraordinary jewelry artistry, traditional artists use this ancient and nearly extinct method of producing jewelry.

Jewelry that morphs —

After the first wear, the entire tremendum collection will begin to metamorphose. The longer time passes, the more it reflects the wearer's uniqueness.

All Tremendum collections are coated with a rhodium plating that begins to fade with the first wear, revealing the peculiar color of the underlying metal. Astoundingly, no two wearers will ever get the identical results as it depends on their unique behavior.

Look for the hashtag #mytremorphed to see how the Tremendum collection has morphed to represent the wearer's individuality.

Packaging That Gives a Message

For packaging, teak wood and glassfiber-reinforced concrete are used. One material is a product of nature and the other is a mass-manufactured product.

These two materials tell a story about how industrial materials became popular and cheaper in society, so locals used them to develop the area and left most wood-materials off the list, causing wood craftsmanship to become extinct.

Perhaps it's a message for our next purpose?
