My journey in mineral collecting and photography has brought me to an unexpected milestone.

For the past year, Shaun Rasmussen, Krissann Morrill and myself had been quietly assembling an article for a magazine publication. Alice Sikorski paved our path and submitted the article to The Mineralogical Record. The article was accepted and was finally published in the November-December, 2020 issue Vol. 51 No. 6.

In my hobby of photographing mineral specimens, I never expected to achieve something of this magnitude. I have no expensive cameras or equipment. I captured all of these photos with a cell phone camera and a GemOro jewelers loupe. I think that's probably the greatest achievement of this project!

Five of my photos were featured of four different specimens from the SK Star Claims. One photo was taken by Alice Sikorski and lastly, a photo by Kevin Shumacher from the G.I.A.'s "Gems & Gemology" online publication.

This issue of The Mineralogical Record is truly a masterpiece and will be sought after for many years to come. 2020 celebrates 50 years since the founding of The Mineralogical Record in 1970 and out of all the issues published in those 50 years, this is the first "centerfold-style" cover. I can think of few specimens in history that deserve such recognition as The King of Kashmir Aquamarine from Pakistan, without a doubt the finest specimen of this species ever discovered.

The specimen above was featured twice in this issue of the M.R. This is another angle that I never showed to the public. Sadly, this specimen was destroyed in a house fire this past year but fortunately the owners are safe. The other three specimens featured in this issue reside in my private collection, The Oculus Mineral Gallery.

The specimen shown above also made its way in the M.R. A doubly terminated Black Topaz crystal in matrix. This uncommon matrix specimen features several topaz crystals on a highly fluorescent host of uranyl chalcedony, fluorite & clinoptilolite.

This phenomenal specimen shown above also made its way to the M.R., featuring five terminations on one end and three on the other. It is truly a one of a kind specimen from the SK Star Claim.

The specimen on the right was the fourth specimen featured in this issue. A remarkable, 3 cm cluster with multiple, terminated crystals coating the surface. Isolated inclusions fade in the upper portion of the largest crystal, displaying a champagne color and flat, basal termination.




I'm very grateful and humbled to have been able to participate and contribute to this unforgettable experience. This is my photo contribution to the Black Topaz article featured in the latest issue of

The Mineralogical Record. I'd like to thank Shaun Rasmussen and Krisann Morrill for giving me the opportunity to join them on this journey and more importantly, the opportunity to create a genuine friendship. You both rock! Thank you to everyone who has followed my work and shared my love for minerals.

Beryl var. "Emerald"

The Rist Mine aka The North America Emerald Mine is without a doubt one of the most important North American Emerald deposits. Like most Emerald-bearing deposits within Hiddenite, North Carolina, many other important mineral deposits can be attributed as well, including Rutile and Spodumene. Hiddenite has long had its place among mineral collectors, making the Rist Mine and nearby Adams Farm icons within the mineral community. As important and individual as the vibrant green Spodumene crystals are within the mineral world, the Emeralds of Hiddenite have indeed been placed in the forefront as North America's largest and highest quality Emerald crystals.



Rutile with green Muscovite, Siderite & Calcite

The Rutile crystals of Hiddenite are among a few of the other treasures found at the Rist Mine. World-class specimens have been noted at this locality for their distinct color and clarity for its type. Terry Ledford was the most notable miner and collector of native minerals in Hiddenite, without question. His collection of personally-mined material is still highly praised among collectors world-wide and highly sought after. My Rist Mine collection consists of several of Terry's, personally mined specimens.

The Rist Mine specimens have become a staple in southeastern mineral collections and continue to serve as some of the finest examples of North American gem minerals to date. Stay tuned for more posts on this amazing material!

Black Topaz, SK Star Claim, Juab Co., Utah - 1.7 cm


Thumbnail sized minerals are highly sought after specimens, especially those displaying exceptional crystal forms. Deposits from both Utah and Mexico are known for their clusters of Topaz, as well as some Chinese deposits. In my personal research, I've yet to see more complexity and variance in crystal clusters as those from the SK Star Claim. In the same respect, the single crystals are just as impressive in form, terminations and inclusions. In this post, I'll be focusing on the exceptional form and focus of "thumbnail" specimens.

 


Black Topaz, SK Star Claim, Juab Co., Utah - 0.9 cm

Many of the Black Topaz crystals exhibit gradients of inclusions that often fade out near the termination or even abruptly stopping; creating a "capped" look. Crystals like the one showed above are less than 1 cm, many only being several millimeters in size. A range of quality can be found from the smallest crystals to some of the largest reaching several centimeters in length.

Single and double terminated crystals are not uncommon at the SK Star Claim, ranging in heavily included specimens that are solid black or even transparent; golden crystals that appear "peppered" with lightly scattered inclusions. I've found that some of the heavily included crystals display a mirror-like luster.

 


Black Topaz, SK Star Claim, Juab Co., Utah - 1.5 x 1.5 cm

Clusters like the one displayed above can be found in a range of sizes. Most of the crystals are floaters, intersecting, penetrating, double terminated and seemingly endless. They are far more uncommon than single crystals and I was fortunate to add some of these clusters to my collection to photograph and I look forward to sharing more with you. Black Topaz is exceedingly difficult to photograph for many reasons but the clusters enjoy any bit of light you shed on them.
