| Obverse description | Octagonal silver ring surrounds a blue-colored tantalum centre disc depicting a stylized celestial wheel or helm motif at centre, encircled by a band bearing all twelve zodiac symbols in relief, separated by radial dividers. The colored tantalum insert shows a golden-orange solar disc at the very centre. The upper field of the silver ring bears the Kazakh-language legend ҚАЗАҚСТАН ҰЛТТЫҚ БАНКІ (National Bank of Kazakhstan) in Cyrillic, while the lower field carries the denomination 100 ТЕҢГЕ. Metallic specifications Ta 999 15g and Ag 925 10g, along with the date 2018, appear to the right on the silver ring, which is further decorated along its octagonal edges with engraved zodiac glyphs. |

| Additional information |
Kazakhstan's bimetallic commemorative program has produced some genuinely unusual material pairings, and tantalum is among the rarest choices any mint has made for a coin center. The metal is extraordinarily hard, chemically inert, and historically associated with capacitor manufacturing rather than coinage — its appearance here reflects Kazakhstan's position as one of the world's significant tantalum producers, giving the choice industrial logic rather than mere novelty.
The Gemini issue belongs to a zodiac series released by the National Bank across multiple years. Tantalum's natural blue-grey tone contrasts sharply against the sterling ring without any applied coloring.
