A very clear, colorless Quartz crystal that looks like a Citrine due to it being included by golden Rutile needles. Very close inspection also shows a few inclusions of flat silvery-black Hematite crystals as well. Overall this is in much better condition than we usually see for Rutilated Quartz crystals, however there are some tiny rough spots so this is not for a strict perfectionist. Nevertheless it is hard to find any Rutilated that is this clean and gem clear. Sources in Brazil have been producing very little and anything this good is sold as cutting rough to the Asian market.

A radiating circular spray of Amethyst crystals that forms a flower-like form. These flowers or suns, as they are also called, are well-known from Irai in Brazil but less well-known from Tamil Nadu in India. The Indian examples often have richer color and brighter luster, but are smaller than the Brazilian pieces. This is a choice Indian piece with excellent form, vivid color and luster, in excellent condition. Very close examination will reveal that many of the crystals a included with tiny needle crystals of golden and red color Rutile. These are still sometimes found in small quantities but the best were found in 2012, this piece is from that period.
Very slender Tessin habit Quartz included by Chlorite. A very delicate specimen with the main crystal doubly terminated and hosting two branching smaller crystals. In excellent condition as seen, the proportions are remarkable too, the thickest part of the main crystal is just 2.5 MM. This piece is from a find in 2015 in the incredible Alpine clefts of Ganesh Himal. There were quite a few nice Tessins in the find but most had damage or were not complete. This is a textbook example of this rather uncommon habit.
Cerussite and Anglesite on Galena
Touissit, Touissit-Bou Beker Dist., Jerada Province
8.9 x 7.3 x 2.1 CM (cabinet)
new year 2021
Cerussite has an incredibly bright refractive index (greater than diamond) so this plate of gemmy, unaltered crystals is striking in person. From Touissit the condition is superb, the crystals have glassy faces, a multitude of forms and contrast well with the dark matrix. There are a few Anglesite crystals present as well and the matrix is a heavy mass of Galena. Most Cerussite is milky or has an altered surface, but gemmy crystals like this are only found in a few localities (all of which are closed). Impossible to capture the brilliant sparkling in a photo but in person this is really impressive.
A golden Barite single crystal with excellent clarity and glassy luster. From finds about 5 years ago at Rosh Pinah, this crystal is included by dozens of perfectly spherical Coronadite balls, and a few are also seen on the exterior as well. These are best appreciated with some magnification which also reveals the zoned nature of the inclusions. Most of the Barite at Rosh Pinah were slender or leafy crystals, this is unusual from just one pocket with this stout form. In excellent condition, some contacting on the lower parts is noted but no damage, the faces are sharp and glassy.
Creedite (purple crystals)
San Antonio Mine
5.3 x 4.7 x 3.4 CM (cabinet)
new year 2021
A well-crystallized older purple Creedite from the 1970 vintage find at Santa Eulalia in the San Antonio Mine. The individual Creedite crystals are glassy lustrous, transparent, in perfect condition and unusually well isolated. The matrix is a dark gossan that adds a nice contrast to the bright Creedites. Ex Glenn Nicol collection. The dark matrix is unusual from this locale, I have only ever seen one other example. Mexican Purple Creedites are far more rare than the orange crystals from Navidad, and good pieces are very hard to come by in recent years.
Mimetite var. Campylite
Dry Gill Mine, Caldbeck Fells
4.9 x2.8 x 1.4 CM (miniature)
new year 2021
A cute miniature specimen with classic curved crystals of mustard-green Mimetite. The Mimetites contrast well with the matrix and have a good "wet" luster. From the famed Dry Gill locality that was at one time the most important source for the Campylite habit. These are now classics in the mineral world and this is an good value for textbook example of the curved barrel shaped crystals.
An simply outstanding Mendip specimen with a large crystal lined cavity inside a Manganese Oxide mass. The void contains choice Cerussite and Hydrocerussite some in twins and others with reticulated forms, nestled on a sparkling Calcite. This Quarry is famed for the rare Lead minerals that are found here in association with the Manganese deposits in the Carboniferous Limestones. The location is unique and has been the source of at least eight new minerals. That said most of the specimens are not often well crystallized or esthetic. This is an exception as the Lead minerals are well formed and make an attractive display contrasting inside the cavity. The Merehead Quarry now known as the Tor Works Quarry began to be noticed about 80 years ago and is a world class source of many other rare species.
