Lilangabi Agate: A New Deposit from Southern Africa

In August 2025, Kent Alcock — prospector and co-founder of Elemental Treasure — discovered an agate deposit in a remote valley in Southern Africa, unknown to the collector world until that point. We named it Lilangabi, from the SiSwati word for flame. Elemental Treasure discovered it, named it, and remains the sole source.

This is not a rebranded material. Lilangabi agate is a distinct deposit with its own character, formation history, and collector feature set — different in palette, structure, and inclusion profile from the Ngabu material we source from Malawi.

Colour and Palette

The dominant palette of Lilangabi agate is warm and saturated: amber, tangerine, mustard, golden-yellow, and deep orange-brown. Chromatism — the gradual shift in colour tone across the band sequence — is a defining characteristic of the material, present across many of the specimens. Colour transitions from deep amber-gold at the outer margin inward through the full band sequence, often with striking tonal contrast between adjacent bands.

Purple and pink chalcedony expressions occur rarely in Lilangabi material, ranging from pale pink to lavender-purple, appearing as a distinct band within the banding sequence. Where present, this is a significant collector feature — in strong contrast to the warm amber ground that defines the material.

Structural Features

Lilangabi agate is structurally complex. The following features have been confirmed across the inaugural release:

• Fortification banding — angular, geometric concentric banding present across the majority of specimens, often bold and well-defined
• Druzy vugs — open crystal-lined cavities are common, frequently with visible goethite needle inclusions or calcite crystal formations on the vug floor
• Eyes — complete isolated nodules with their own concentric banding, suspended within the chalcedony ground; including rare double eyes sharing a common wall
• Bullseye — a perfectly formed isolated nodule with tight concentric banding
• Perimorphs — outer margin structures confirming complex formation history, present across multiple specimens
• Floaters — isolated banding forms suspended independently within the chalcedony ground
• Waterline features — horizontal deposition layering extending across the full width of the interior in some specimens
• Scalloped banding — present on inner band edges, particularly adjacent to vug walls
• Plume inclusions — dense plume fields at the margins, adding structural complexity
• Chromatism — a recurring feature across many specimens; a defining characteristic of the deposit

Formation and Provenance

Each Lilangabi agate is a natural stone formed over millions of years. Specimens are transported to our workshop in South Africa, where they are cut and hand-lapped in house. No treatments, dyes, or enhancements are applied. What you see is the natural character of the stone.

Availability

Lilangabi agate is available exclusively through Elemental Treasure. This inaugural release comprises a limited number of collector-grade specimens, each sold individually with full specifications and unedited photography. Browse the current Lilangabi collection at elementaltreasure.com.
