11s

A ”ten”. For some of us of a prior generation, images of an iconic 80’s movie come to mind. Today a viral TikTok video or an NFT might very well be considered a ”ten”. The phrase ”that’s a ten” became integral to our cultural vernacular. As human beings, we need to quantify and validate our personal aesthetic choices; hence the term ”10” has come into being. When categorizing legendary accomplishments, we use the term G.O.A.T. (Greatest of All Time). Lebron James, Vincent Van Gogh, and the 2016 U.S. Women’s Soccer Team epitomize this concept quite well. In the physical realm, we tend to use the terms iconic, unprecedented, priceless, and legendary to affirm the object’s importance in popular culture. In the subjective world of fine minerals, a select few specimens reach the lofty status of ”10s”. The simple fact is that certain mineral specimens are so dramatic, aesthetic, or scientifically superior that most advanced collectors would be proud to own the piece or even have the opportunity to visually or physically evaluate the natural wonder. 

Da Vinci’s Mona Lisa, an absolute classic, would be considered an 11. Why? The average viewer knows an “11” when they see it. More specifically, it captures your brain, heart, and soul. You realize that all the 10s you’ve ever seen fall short in the face of the etherealness emanating from this work. It remains forever etched in your mind as an item that reaches the sublime. 

Thus, we must also acknowledge our greatest artist of all, the earth itself, when it comes to its natural mineralogical creations, and so we have found a few different types of 11s in this realm. It is critically essential to attribute specific criteria relative to the designation of an “11”. Scroll down to experience many of the world’s natural masterpieces.

Tourmaline on Quartz - Pala, California USA

In 1972 the Queen mine produced a single pocket of approximately 38 extraordinary specimens of red tourmaline with glassy blue terminations. The color was a rose to deep red hue with sapphire ”bluecaps” and crystal size up to an exceeding a ”beer can” (we know this due to the amount of beer consumed during the extraction of the pocket). This truly natural wonder resides in the Smithsonian Institution Gem and Mineral Collection in Washington, D.C. In the early 1970s, legendary Smithsonian curator Paul Desautels named the piece ”The Candelabra”. Most major museums competed against each other to acquire specimens from this famous find. Ironically, this extraordinary tourmaline find is called the ”Bluecap” pocket, and the ”candelabra” resides in a regal position in the world-renowned mineral and gem hall mere steps away from the deep blue Hope Diamond. Exalted status indeed…

Benitoite - California, USA

19th-century mineralogists theorized that the trigonal bipyramidal crystallography of benitoite had to exist ”somewhere” in the mineral kingdom. In 1907, benitoite was discovered in one locality near the headwaters of the San Benito river in California, validating the 19th-century mineralogists. The sapphire-blue gem mineral is one of the rarest and most desirable species in the mineral world.

The refraction index of benitoite is actually higher than diamond. Imagine sapphire blue with the fire of a faceted diamond.
The benitoite shown here is truly a ”show-stopper”. With huge crystals, up to 1 1/4 inches, excellent blue color, perched on snow-white natrolite, this specimen is a candidate for the world’s best.

What makes this specimen an 11: 

● Superior crystal size

● Extreme rarity – one primary locality
