Oyaide INS-BD Black Diamond Hematite stone insulator

The INS-BD is a natural stone insulator of black diamond (hematite) cut at high precision, bearing a beautiful metallic black gloss. It combines high-strength and high-density physical properties, with a Mohs hardness rating of 6, relative density of 5, and has a trigonal crystal structure consisting of Fe203.

Its tone is clear and straight. While brimming with a core, strong sense of power, it never exposes users to any peaks or dips. It is a monitor-like masterpiece that is just right for highly faithful playback.

INS-BD uses carefully chosen natural stones, scrupulously machined one by one at the hands of professional jewellery artisans in jewellery workshops in Japan. Its surface lets off a beautiful gloss, finished with a mirrored surface polish and combined with a highly flat surface.

Aside from the obvious standalone use, embedding the INS-BD in a multi-base insulator allows for even more enjoyment in tuning.
In addition to its use as an insulator, it can be used as a tuning chip by being placed or stuck onto an instrument.
Handle with care as the product may crack due to strong impact or being subject to pin-point loads.
Enjoy the feel of the natural stones with their one-of-a-kind patterns and colours.
