Trio of gem Beryl specimens from the Jon Sigerman collection. Jon is a collector who specializes in gem crystals and has an excellent eye for color. The suite includes a 1cm Emerald from Jos, Nigeria with saturated green color and a steep termination. A 1.5cm etched orange Beryl from Karoi, Zimbabwe fully etched all around with bright glassy faces all over and uncommon color. Finally, a single Red Beryl crystal 7mm tall, complete all around with gem rough value. All crystals are complete and undamaged. Ex. Jon Sigerman collection.

Scuptural, aesthetic Copper crystal from the Rocklands Mine. Well crystallized all around with a beautiful form and good patina. Good from either side.

Stunning single Wulfenite crystal of the high quality and color that made this mine so famous. Highly lustrous translucent to transparent crystal - you can read through it in the center! Complete front and back with an uncommon form.

Large specimen loaded with lustrous, snow-white crystals of Tarnowizite. More commonly seen from Tsumeb, Tarnowitzite are also found at Touissit and can get very good. Nearly pristine, the entire front is covered with crystals, with only a couple missing. There is also a vug on the side with additiional crystals. Comes with an old John Mitchell label showing a date of 2004.

Transparent gem pencil Tourmaline. Nearly flawless pink crystal with a green termination. Interestingly, there appears to be a tiny gem nodule grown right at the very tip. Complete and undamaged.

Thick, orange Wulfenite crystals on satiny dark green Mottramite. The contrast of colors and textures make for a beautiful and uncommon specimen. The Wulfenite crystals are well isolated and well distributed, and reach 1.4cm in size. From a 2013 find at the Ojuela Mine.

Scalenohedral white Calcite crystals on green Conichalcite. This is the largest, finest specimens of this type from the Ojuela that I ever recall seening. In most similar specimens, the Calcite occur as small drusy rhombs - this one has larger sized Calcite crystals to 1.5cm. The Calcite are in excellent condition with just a couple missing crystals on the very edge, the vast majority are perfect. A great addition to a Ojuela Mine suite. Ex. Allen Winans collection.
