Kerch peninsula (Kertch peninsula), Crimea peninsula, Crimea Oblast', Ukraine
Small Cabinet, 5.6 x 4.6 x 2.7 cm
This fine specimen features a well-placed vug lined with highly lustrous, dark sea-green vivianite needles to 2.8 cm aesthetically set in a fossilized mollusc shell from the Kerch Peninsula of the Ukraine, near the Black Sea. Both sides of the clam have been partially replaced with blue vivianite. This portion of the deposit is now mined through and gone. The calcium and phosphate needed to form this species are both derived from the original shell material.
