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.

The Meaning Behind TREMENDUM
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.

PACKAGING
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?
Every Order Empowers Indigenous Education
For every purchase, TREMENDUM donates a portion of the proceeds to the Sokola Institute, which supports education for indigenous communities across Indonesia.
We believe proper education will help preserve local wisdom, protect nature, and empower future generations.
