Just wondering where would I be able to purchase the dragon head

It appears the dragon head is made by Mo Orgone Art. The only link I can find to obtain the dragon heads is through this facebook group which she appears to run: https://www.facebook.com/groups/530635537142895/

While looking, I also found this etsy page that makes similar dragon heads decorated with crystals: https://www.etsy.com/shop/BellsWingandBell?ref=simple-shop-header-name&listing_id=905208317&section_id=30618591

Hope that helps~!

Heres your semiregular reminder that opal is one of the worst possible gemstones for engagement rings and tumblr posts about how pretty opals are and how diamonds are bullshit and we should all wear opal rings are not actually well informed or your friends

@sirfoggybrain Of course!

So opals, as we all know, are gorgeous stones

I will at no point deny that, theyre stunning and look different from every angle and in every lighting, the plays of color are insane, and they can be used to make beautiful jewelry, including, unfortunately, engagement rings. Which then have the tedency to do what opals do best, which is break and chip

The problem with opals is their position on the mohs hardness scale: they are a 5.5 to a 6.5. This in on par with glass. You can break one of these with glass or a knife or any piece of metal. The woman on the left broke hers by accidentally knocking it against her desk. Engagement rings are meant to be worn every day, and they are worn on your hands, which are high contact body parts. Opals cannot properly hold up to everyday use, and will become damaged unless you are lucky. It is, in my opinion, best not to risk it- this is a special ring, your forever ring, an object that meant to be worn daily and symbolizes your love and is, if worst comes to worst, something to hawk if you are desperate for cash to continue to live. You do not want it to break. Moonstone- which is another one i see recommended a lot- is the same way. Engagement rings are special. I would not ever in good conscience be able to recommend something that fragile to be someones forever ring.

Diamonds are not recommended just because of the diamond industry (which is bad, i agree! Please make sure your diamond is ethical if you chose to get one, and my personal opinion is that lab made is better) but because they are the most durable stone out there. You cant break your diamond.

Theres nothing wrong with wanting a colorful, flashy engagement ring, but an opal is not the stone for you. You want a gemstone that is an 8+ on the hardness scale- so stones like emeralds (if youre careful with it!), rubies, sapphires (which come in all sorts of colors), moissanite (typically white, but with twice the fire and brilliance of a diamond), morganite, colored diamonds, and alexandrite are all good choices. Alexandrite even changes colors depending on lighting!

TL;DR: opals are too soft and fragile for an engagement ring. Get opal necklace instead, and pick a tougher stone for your engagement ring.

Topaz is also 8 on the Mohs scale, and Aquamarine is the same stone as Emerald but in a different colour. Both are also worth considering!

Fun fact: the stereotypical banding pattern seen in agate (like above) is due to alternating layers of quartz and chalcedony!

A balance of playful yellow and passionate red, orange commands attention without overwhelming. This often flamboyant color brings to mind citrus and sunsets, fall leaves, and jack-o’-lanterns. Orange has even been found to stimulate appetite and creativity in humans.

Here, patterns etched in sandstone appear like an artist’s rendering of the Utah landscape. Dramatic sandstone formations are the main attraction at the state’s Arches National Park.

Weird peeve time. Calling lab grown gemstones “fake” is stupid because it’s the same shit just not formed naturally. An artificially grown diamond is the same shit as a natural diamond it is the exact same material bro it’s all fuckign carbon

It’s carbon it’s pretty and it didn’t involve slave labor what’s not to love??? Hi I’m having geology opinions tonight apparently. And I’m right

There is so much bullshit in the diamonds industry to be mad about tbh. It also ties into the bullshit of the wedding industry as a whole but we don’t have the time to unpack all that

not even going to lie, the day i learned i could get like 15 lab grown rubies the size of dimes for $20 is the day i spent $20 on rubies, and i have never once said to myself “man, i wish this cost $1,600 and the lives of eight children to produce”

We are a pro-lab-grown mineral blog here, not only is it massively cheaper but massively more ethical as well in many cases.

Besides, wearing a ring made of SCIENCE! sounds pretty excellent and celebratory.

  • a map showing tectonic plates on your wall 
  • tracking the movement of continents across millions of years 
  • identifying rocks you see in everyday life
  • the enticing glow of molten lava

  • eagerly showing your friends your rock collection
  • carefully analyzing a seismograph
  • the excitement of breaking open a geode
  • a hammer and chisel that fit comfortably in your hands
  • being fascinated by rare geologic formations, imagining how the earth must have shifted to create them
  • examining the great unconformity of the grand canyon
  • looking for signs of glacial striation and abrasion
  • the vivid colors of an active hot spring 
  • polishing rocks you’ve collected in a tumbler, watching them go from rough and angular to perfectly smooth
  • the harsh beauty of volcanic eruptions
  • wishing you could have seen pangea or gondwana in their day

Sunsets and Stargazing on Mt Teide

Despite absolutely loving my stay at the Puravida Jardín Tropical Hotel, the surrounding area of Costa Adeje was personally doing nothing for me, and as such I found myself not enjoying my time in Tenerife as much as I had in the rest of the Canary Islands. Having ventured out on several occasions in search of things to do, exciting places to photograph or even just to buy some water, I felt as…

Mount Holyoke has long been the pioneer for women studying disciplines that were male-dominated. Geology was no exception. In a 1922 edition of the Alumnae Quarterly magazine, faculty member Mignon Talbot wrote an article arguing against the commonly-thought idea that women could not study geology and geography. In her article, Talbot explains how women would bring a beneficial contribution to the geological fields, and how Mary Lyon had always advocated for women to study science. Although Mount Holyoke did not itself have a formal geology department until the 1933-34 academic year, the Alumnae Quarterly article certainly helped create a case. Geology continues to be an important scientific study at Mount Holyoke up to the present day.

Lapilli, meaning ‘little stones’ in Latin, can have diverse origins, but the example shown on a photograph is more precisely called accretionary lapilli.

Accretionary lapilli form during a volcanic eruption in the ash cloud. When big volcanic eruption occurs, a volcano will blow a huge cloud into the atmosphere. Such cloud will contain massive boulders, smaller rocks, volcanic ash and gases etc. Rocks are heavy, so they fall back down fast, however, ash and gases do not. The most abundant and important in this process gas is a water vapour.

Mix fine ash and water vapour/steam together and what you get is an airborne mud. Water vapour sticks ash particles together, so as the huge turbulent ash cloud grows and mixes, more and more ash particles come together to form little balls (lapilli) which then rain down like hail once they get too heavy.

This layer formed after such rock rain in Hawai’i Island (Big Island).

Dunes pictured are at elevation of around 3000 metres (~9850 feet) above sea level, located in western part of the Himalaya Mountains.

Steep valley walls that stick out about 1000–2000 metres (3280–6560 feet) above the valley floor create a narrow corridor. This corridor captures major air mass movements which blow around the sands on the valley floor that eventually make up dunes.

Arch-shaped patters are sand layers within old dunes that have partially eroded. The erosion has exposed the internal structure revealing how the dune was constructed.
