Adamant Co., Ltd. (アダマンド株式会社 Adamant Kabushiki-gaisha) is a component manufacturing company based in Tokyo, Japan. Its name is from the word adamant, which was derived from the Greek word adamas meaning "diamond". At of its founding, Adamant's main products were watch jewels that were made of a hard material.

In 1957, Adamant separated from Namiki Precision Jewel Co., Ltd.[1] It started sales of jewel bearings for watches and clocks and began to manufacture cap jewel, hole jewel, impulse jewel and pallet stone. In 1980, it started manufacturing ferrules for the optical communication industry utilizing injection molding engineering and polishing techniques.

Products

Photonics

Zirconia ferrule, sleeve, receptacle and connector incorporating Injection molding techniques. Lensed fiber, lens is formed on top of optical fiber which is equivalent with human hair.

MEMS (Micro Electro Mechanical System)

Started full foundry service covering development →test production　→and OEM Manufacturing of MEMS in tie-ups with Micralyne Inc. in Canada.[4][5]

Pursuant to joint development with Micralyne Inc. for optical sensor device incorporating MEMS.VOA（Variable Optical Attenuator）and optical switch with hermetically sealed in metal package

Fine industrial jewelINE INDUSTRIAL JEWEL

Capillaries for bonding tool, wedge, also, ruby knife, pellet, dental block for medical device, physics and chemistry.

Advanced material

Variety of color Ceramics available such as White, Black, Blue and Brown. Featuring glossy by polishing finish and a high-class touch. LTCC（Low Temperature Co-fired Ceramics）[6] are co-fired at low temp.(900℃) in process which makes silver material possible in order to use as a conductor. Suited for RF products due to low loss. Also, multi-layered and flat substrate can be made easily. Highly accurate, high-density mounting are realized.[7]
