Scientific identity, documented history, and community contexts are presented with sources. TÁWID’s contemporary design interpretation is identified separately.

Material identity

Angelite is a trade name for pale blue-grey, fine-grained anhydrite. The gemmological classification maintained by the National Museum of Natural History in Sofia associates this name with material from Peru. Anhydrite is calcium sulfate, CaSO₄; unlike gypsum, it has no water incorporated into its chemical formula.

The Handbook of Mineralogy records hardness around 3–3.5 and several cleavage directions. These properties make it a delicate ornamental choice beside quartz or beryl. A soft, evenly coloured bead can be visually appealing without being a durable everyday substitute for a harder stone. [1] [2]

Documented historical context

The National Museum of Natural History in Sofia classifies angelite as a trade name for pale blue-grey, fine-grained anhydrite from Peru. The available references do not establish the first use of the commercial name or an ancient ceremonial tradition attached to it.

Anhydrite has a much broader geological distribution. It occurs in evaporite deposits, can form through dehydration of gypsum, and is also recorded in igneous, fumarolic, and hydrothermal environments. Its chemistry therefore links materials formed in very different landscapes. [1] [2]

A Philippine geological connection

The Handbook of Mineralogy records anhydrite at Mount Pinatubo. This is a Philippine volcanic occurrence of the same mineral species. It is not identified in that reference as blue gem material or the source of the beads in this catalogue. No historical Philippine adornment use is established by the occurrence record. [1]

TÁWID’s contemporary interpretation

Payapang Diwa is TÁWID’s contemporary title for composure and considerate conduct.

Material note

Protect from scratches and hard knocks; avoid soaking. The trade name should not be used as evidence of spiritual effects.
