Zultanium

Zultanium Atlas is the documented reference and toolkit for Zultanite — the
rare colour-change diaspore from the İlbir Mountains of Türkiye that shifts
from sage-green in daylight to champagne indoors to soft raspberry by candle.

Built for collectors and buyers who want facts they can trust and tools they
can actually use — not marketing.

TOOLS YOU CAN USE
• Gem Studio — photograph your own stone and see it relit across the three
illuminants, with a draggable light scrubber.
• Authenticity Checker — a guided read on a stone’s plausibility. Decision
support, not a certificate.
• Smart Vault — an encrypted, on-device record of each stone, sealed with a
tamper-evident fingerprint. Your data never leaves your device.
• Stone Passport — document a stone and a due-diligence checklist.
• Design Studio — sketch a ring setting around your stone.
• Market & Exchange — a documented reference value at live ECB exchange rates.
A reference figure, not a live market quote or appraisal.
• Compare Stones — Zultanite next to gold, diamond, alexandrite and more.

THE REFERENCE ARCHIVE
• Sourced articles, buying guides, and how-tos.
• A gemology glossary and a plain-English FAQ.
• Ask and Search the whole archive — every answer cites its source, and the
app does not invent facts.

HONEST BY DESIGN
We don’t quote a “daily Zultanite price” — no such exchange exists — and we
never claim a stone is genuine for you. A recognized lab report (GIA / IGI) is
always the final word.

PRIVATE BY DESIGN
No account. No ads. No tracking. No analytics. Everything you create stays on
your device.

Independent reference. Not affiliated with, endorsed by, or sponsored by the
Zultanite® trademark holder.
