Collecting tips
- Aquamarine Prospecting. Look for granitic pegmatites, especially those associated with mica schists or gneisses. Aquamarine often occurs with quartz, feldspar, and mica. Examine weathered outcrops and stream beds for eroded crystals.
- Pearl Sourcing. Natural pearls are extremely rare and typically found by divers in specific mollusk beds. Cultured pearls are farmed. For collectors, understanding the origin (natural vs. cultured, saltwater vs. freshwater) and type of mollusk is crucial.
- Identifying Aquamarine. Distinguish from blue topaz by hardness (aquamarine is harder) and pleochroism (aquamarine shows stronger pleochroism). Its hexagonal crystal habit is also a key identifier.
- Identifying Pearl. The 'tooth test' (rubbing gently against a tooth to feel a gritty texture) can help distinguish real pearls from imitations (which feel smooth). Examine the luster and overtone colors. X-ray analysis is definitive for natural vs. cultured.
