Best Seasons

The best seasons for opal hunting in Arizona are typically late fall through early spring, when temperatures are cooler and conditions are more favorable for exploration. During this period, average daytime temperatures range from 60°F to 80°F, reducing the risk of heat-related stress.

Data indicates that precipitation levels are minimal, averaging below 1 inch per month, which keeps the terrain dry and accessible. Moreover, lower UV radiation levels during these months minimize potential sun exposure risks.

These favorable climatic conditions allow you to spend extended hours in the field, enhancing your chances of locating opal deposits. By strategically planning your excursions around these months, you maximize both comfort and efficiency in your opal hunting endeavors.

Identifying Opal

Having selected the best season for your search, you now need to focus on identifying opal by recognizing its unique physical characteristics and geological markers. Opal's distinct features make it recognizable if you know what to look for.

Here are key identifiers:

• Color Play: Opal displays a phenomenon known as 'play of color,' showcasing a variety of colors when light passes through.
• Hardness: With a Mohs hardness of 5.5-6.5, opal is relatively soft compared to other gemstones.
• Specific Gravity: Opal's specific gravity ranges from 1.98 to 2.25.
• Fracture: It typically exhibits a conchoidal fracture.
• Geological Context: Often found in volcanic ash beds or areas with high silica content.

Understanding these attributes guarantees you can accurately identify opal during your Arizona expeditions.

Cleaning and Preserving Finds

To guarantee your opal retains its brilliant color play and structural integrity, start by gently rinsing off any surface dirt with lukewarm water. Avoid using soap or chemicals, as these can damage the opal's delicate structure. Once cleaned, dry the opal with a soft, lint-free cloth. For long-term preservation, store the opal in a cool, dry place, ideally wrapped in a damp cloth to maintain humidity levels.
