Geological Differences
Montana Sapphires (Yogo Gulch & Rock Creek)
Formed in igneous rock deposits in Montana's mountains. The unique geology creates:
- Color: Teal, blue-green, light blue (iron-rich, low titanium)
- Clarity: Exceptionally clean (minimal inclusions)
- Size: Typically 0.5-1.5ct (larger stones rare)
- Treatment: Usually unheated (natural color is desirable)
Australian Sapphires (Queensland Anakie)
Formed in basaltic lava flows over millions of years. The geology creates:
- Color: Parti-colored (blue, green, yellow zones), deep blue, teal
- Clarity: Eye-clean to minor inclusions (silk common)
- Size: 0.5-3ct+ (larger stones more common)
- Treatment: Often unheated (parti-colors are natural)
🔬 Geological Fact
Montana's teal color comes from high iron, low titanium. Australian parti-coloring comes from varying iron/titanium concentrations during crystal growth—creating color zones that are geologically unrepeatable.
