Unakite is a superb, fairly widespread, rock comprised of Pink Orthoclase (Feldspar) and Inexperienced Epidote, magnetite, chromite, ilmenite, apatite, zircon, and different minerals. If I see Unakite, I at all times choose it up as a result of it’s so irresistible. One thing concerning the Pistachio Inexperienced and the Pink Orthoclase that makes it irresistible.
Feldspar is split into two teams: 1. Orthoclase Feldpar incorporates Potassium, whereas 2. Plagioclase Feldspar incorporates Calcium and Sodium. Feels like issues that may be wholesome to eat. I suppose you would attempt it IF you may have a very good dentist.
Unakite is a rock used for jewellery, carvings, beads, headstones, sinks, and lots of different issues.
TRIVIA ALERT: Unakite is typically used as an architectural and ornamental stone. Slabs of unakite are used as flooring tiles, going through stone, stair treads, and windowsills. Its most distinguished use is as a trimming to the entrance steps of the Smithsonian Nationwide Museum of Pure Historical past in Washington, D.C. Additionally it is used as flooring tiles on a touchdown on the south entrance.
Unakite has a MOHs hardness of round 6, so it’s a sturdy rock for any use (besides consuming). Bonnie likes a number of bigger items in her rock gardens.
Bonnie has advised, previously, that I write a weblog about Unakite. Whether or not we’re rockhounding within the Higher Peninsula, or domestically, we at all times discover Unakite. It deserved to be featured.
I typically don’t write boring, difficult, detailed, scientific explanations of how rocks are fashioned, however it’s best to know that Metamorphic rocks, like Unakite) have been fashioned by warmth and stress changing one mineral into one other. You’ll be able to learn sufficient about a lot of these rocks to completely fill your mind, and explode out your ears. There are literally educated those who do nothing however research forms of Feldspar.
Orthoclase is within the Potassium Feldspar Group of Feldspars (as I beforehand talked about). Different supplies I take advantage of for jewellery from this group embody Albite, Amazonite, Moonstone, and Labradorite. Within the Higher Peninsula some rocks include a Feldspar referred to as Adularia. Chlorastrolite (Greenstone) typically include this orange/pink Adularia.
Sufficient of this scientific trivia; lets discuss my newest creation.
Throughout one among our latest rockhounding journeys, I picked up assorted Unakite rocks, from dust roads that we typically hunt. One of many Unakite stones I plucked had an Epidote “bullseye” on it. By no means in 40 years of searching rocks, have I seen such a sample. That rock was thrown right into a bucket and later sorted.
Sorting, after hunts in NW Michigan, includes separating out the Petoskey Stones by high quality, and all the opposite random rocks by whether or not I need to make jewellery from them, put them in seize luggage, or throw them into the driveway. That bullseye rock was dumped within the “do one thing with this container”, and promptly forgotten. This was maybe a pair months in the past.
I regarded down yesterday and seen that “Bullseye” taking a look at me from a container below my workbench. I swear, that rock was ordering me to do one thing with it. So I minimize out the bullseye, and used it as a base for chopping a cabochon. As I regarded on the polished cab, I additionally see it’s sprinkled with a metallic silver-colored mineral, that I should have a look at later below a microscope. In case you are pretty certain what these little bits of metallic are, let me know.
I introduced that Unakite proper as much as the home, and wrapped it up into a pointy piece of bijou. To say this piece of bijou is “Eye Catching” can be an understatement. Eye sweet with a watch in it. I’ve named this piece of bijou…don’t be shocked..”EYE CATCHING”. Verify this one-of-a-kind Unakite out!
