About Us
Kiara Jewellery Japan is rooted in a legacy of trust and excellence. Founded in 1999 in Kofu, Japan, our parent company AB Diamond began as a diamond trading firm. Over two decades, we built a strong reputation in the diamond industry through integrity, expertise, and dedication to quality.
In 2021, we expanded into jewelry manufacturing with the creation of Kiara Jewellery Japan, marking an exciting new chapter focused on crafting accessible luxury. This transition allowed us to bring our design vision to life—blending modern aesthetics with Japanese precision.
By 2025, Kiara Jewellery has grown into a credible and trusted brand, participating in multiple jewelry exhibitions throughout the year. As part of our global expansion, we are preparing to establish our presence in Hong Kong in early 2026.
