HARIO Lampwork Factory
About Us
HARIO Lampwork Factory is a glass jewelry brand by HARIO, a Japanese maker of heatproof glass founded in 1921.
Each piece is carefully handcrafted in Japan, shaped from clear glass into delicate forms inspired by nature.
Lightweight and refined, our jewelry is designed to bring a quiet sense of beauty into everyday life.
Our Story
HARIO began as a manufacturer of heatproof glass for laboratory use.
Over time, its craftsmanship expanded into coffee tools, tea ware, and lifestyle products—always rooted in precision and quality.
The idea for glass jewelry was born unexpectedly.
After the Great East Japan Earthquake, a furnace produced pieces of glass with an unintentional, fleeting beauty.
In 2015, HARIO Lampwork Factory was created to carry forward the company’s original glass working techniques and transform them into wearable forms.
Design
HARIO’s heatproof glass allows for exceptional flexibility—able to be stretched, shaped, and refined into intricate, organic designs.
Each piece captures a moment of nature:
light passing through leaves, the softness of petals, the stillness of water.
The result is jewelry that feels both delicate and enduring.
Craftsmanship
Every piece is handcrafted by skilled artisans in workshops across Japan.
From shaping the glass to assembling the final form, each step is done by hand—preserving techniques that have been refined over generations.
Service
We believe jewelry should be worn and cherished for years.
If your piece becomes damaged, our artisans can repair or replace both glass and fittings.
Our repair service ensures your jewelry can be enjoyed for a lifetime.
