*Origin ---> *Tanzania's Umba Valley* — world's premier *Color-Change Garnet* source since 1978, producing *strongest color shifts* globally.
*Market ---> *Untreated Color-Change Garnet* above 2.5ct commands *extraordinary premium* — less than *1% of all garnet production*.

*Jewelry Design ---> *Shifting orange-to-pink oval* at 8.67mm — a *magical dual-personality centerpiece* for bespoke collector jewelry.
**WHY THIS GARNET IS EXTRAORDINARY**
✓ *Alexandrite Effect*: *Yellowish orange to pinkish red* — dramatic shift rivaling finest alexandrite
✓ *Completely Untreated*: ICA-certified *zero enhancement* — authentic geological miracle
✓ *Umba Valley Provenance*: World's *premier color-change source* — commands *40–60% premium*
✓ *Pyrope-Spessartine Rarity*: Rare *mixed crystal composition* — fewer than *1% of garnet production*
✓ *ICA Certified*: Color-change *phenomenon independently confirmed* by laboratory testing
Comments:
───────
● *Alexandrite Twin*: *Color-Change Garnet* — dramatic shift *rivaling finest alexandrite* globally.
● *Zero Treatment*: ICA *"None"* — *completely natural* phenomenon, museum-grade collector premium.
● *Umba Provenance*: *Tanzania 1978 discovery* — *strongest color shifts* of any garnet source.
● *Warm Palette*: *Yellowish orange to pinkish red* — *most desirable* color-change transformation.
Clarification: ICA GemLab confirms *color-change phenomenon* and *zero treatments* — 100% natural alexandrite effect, *Tanzanian Umba Valley* provenance, museum-grade collector material.

Photography & Image Accuracy:
-----------------------------
- While our HD photos provide detailed static views, we highly recommend watching the included videos for a true-to-life depiction of the gem's dynamic qualities, including color shifts, brilliance, refractive index, light play, and luster in motion.
- All items are photographed individually using professional DSLR/macro equipment in controlled lighting (LED, daylight-balanced ~5000K).
- Photos are not heavily edited; minor cropping may be applied to represent the gem accurately.
- Images may reveal inclusions or features in greater detail than the naked eye—please examine them carefully. Colors can vary slightly due to screen and lighting differences.
