Large deep greenish yellow crystals of Prehnite over Graphite. Merelani Prehnite is considered by many, including me, to be the best in the world, and what has been produced in the last year or two has been the best. This beautiful specimen is a perfect example of this quality. Large translucent crystals with good color. Minor damage, mostly limited to the very edges. A large example for the locality with uncommonly large, good crystals.

Red Wulfenite crystals on matrix. Fine and undamaged crystals. From the Don Boydston collection acquired by John Seibel in 2005.

Colorful and aesthetic Merelani specimen with gem Tsavorite crystals, a couple small Diopside crystals, and white Calcite crystals all atop Graphite. The largest Tsavorite is 5.5mm wide and transparent.

Glassy green Tsavorite crystals on Graphite. The largest Tsavorite is 9mm wide and undamaged.

Complete octahedral Spinel crystal with sharp, glassy faces and good red color. Minor chipping on a couple points, but overall in excellent condition. Weighs 7.4 grams with small gem zones. One of the best I was able to get from the 2018 finds.

An open vug in sulfide matrix lined with Calcite, tiny needle Quartz crystals, and flattened rhombs of pink Rhodochrosite. Undamaged and very bright and clean looking.

Sphalerite, Tetrahedrite, and Pyrite crystals form a classic, quality Peruvian specimen. Little to no damage.

Somewhat flattened, spherical cluster of Azurite crystals with areas altered to Malachite. Complete all around and undamaged with a small point of contact on the bottom.

Fossil bivalve shell that has been replaced by translucent golden agate. These are found on the surface, having weathered out of the surrounding rock formations. There are about 40 different species found at this deposit. Although they could have weathered out of different formations, they are all believed to be Eocene in age. Most are broken pieces and weathered and perfectly preserved examples such as this are uncommon, probably less than 5 percent of what is found.

Octahedral purple Spinel crystal from a new find. Complete all around with typical pitted growth but only very minor chipping. Good luster and translucency.

Amazing double-terminated Vayrynenite on matrix. Matrix Vayrynenite are hard to find, let alone a double-terminated crystal. Good flat, smooth termination faces on both ends with natural pitting along the prism faces. As a bonus there are small Vayrynenite crystals (5 to the left and 2 to the right) attached to the matrix that add even more opulence to an already rare piece. One of the small crystals is also double-terminated. Undamaged.

Facet quality 'lipstick' Tourmaline of light green grading up to a red termination. One of the small side crystals has a chipped termination, otherwise the enire piece is undamaged. Weighs 7.39 grams.

Orange Wulfenite crystals that contrast well against the white Calcite matrix. One crystal is a perfect, undamaged 1cm transparent 'window pane'..
