## What is 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.
It is built for collectors, buyers, and the curious who want facts they can
trust and tools they can actually use — not marketing.

THE TOOLS (the part you can’t do on a website)

• Gem Studio — photograph your own stone and see it relit across the three
  illuminants, with a draggable light scrubber.

• Authenticity Checker — a guided, step-by-step read on a stone’s plausibility
  (colour-change quality, cleavage, inclusions, paperwork). Decision support —
  not a certificate.

• Smart Vault — keep an encrypted, on-device record of each stone, sealed with
  a tamper-evident fingerprint that flags any later change. Your data never
  leaves your device.

• Stone Passport — document a stone and work through a due-diligence checklist.

• Design Studio — sketch a ring setting around your stone.

• Market & Exchange — a documented reference value converted 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 fast, plain-English FAQ.

• Ask and Search across 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. Reference figures are documented and clearly labelled.

PRIVATE BY DESIGN

No account. No ads. No tracking. No analytics. Everything you create — vault
records, photos, passports — stays on your device.

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