More than 4,000 naturally occurring minerals—inorganic solids that have a characteristic chemical composition and specific crystal structure—have been found on Earth. Minerals are typically formed when molten rock, or magma, cools, or by separating out of mineral-rich water, such as that in underground caverns. Many minerals form beautiful crystals, but the most prized of all are gemstones. Uncut gems are often fairly ordinary looking. It's only when they are cut and polished that they obtain the brilliance and lustre that makes them so valued. Historically gems have been divided into precious and semiprecious classes. These are from the semiprecious class.

Over the last few years we've spent a ton of time in the Mark Trail Wilderness area of North GA, but for whatever reason I was unaware of Gemstone Falls. This waterfall is quite unique in that it flows directly into the Chattahoochee River about a quarter of a mile downstream from the Low Gap & Chattahoochee confluence. There are a couple of options to reach this waterfall - one which requires an off trail bushwhack down a very steep rock face or the option I chose which is to (simply) river walk down the Chattahoochee. I feel confident the option I chose was the right one as outside of a couple of stretches it was mostly a pleasurable stroll. Even though the water levels are down here in the Summer I was quite impressed with the setting & took a few minutes for some swimming in the swimming hole there at the base. Early spring would probably be the best bet to visit this one before too much growth & during higher waterflow. I'll be making a return visit at that time next year!
I put together a quick video of the adventure as well if you'd like to check it out:

Thanks so much for visiting! :) -H3
Today's prompt was A Gemstone. Not being much of a gemologist or a jeweller, I asked my old friend, Mr Google and he pointed me at an Aquamarine which I purchased on-line so that I could sketch it for today's prompt. It was a lot smaller than I'd anticipated, but with the help of a camera and a macro lens I got a big enough image to sketch the gemstone you see here.

You didn't really believe that story, did you?

While watering, I noticed that water drops on a cobweb had formed a gemstone veil over a nasturtium.

Most gemstones are minerals and are cut from naturally occurring crystals. To qualify as a gem, the specimen should be hard and tough to resist scratching and have beautiful clarity, colour or 'fire'. Value is based on rarity and rare quality.
Most gems are coloured by a limited number of metals present either as impurities or as essential constituents of the atomic structure.
The most common minerals affecting colour are; chromium, iron, manganese, titanium and copper.
It is chromium which produces the intense red of ruby and the brilliant green of emerald. In garnet, spinel, sapphire, peridot and chrysoberyl it is iron that is responsible for the more subtle red, blue and yellow colours. The best sapphires are coloured by both titanium and iron whilst copper is responsible for the blue and green of turquoise and malachite, and manganese the pink of rhodonite.
The most important coloured stone localities in the world are the Mogok area of Burma, Sri Lanka, Brazil, the Malagasy Republic Madagascar, and, more recently, East Africa. Each of these areas produces a number of different gemstones in significant quantities.
Although coloured gemstones –such as emeralds, rubies, and sapphires- have been mined since ancient times, they are non-renewable resources and their supply from geological deposits is finite. However, unlike many other resources, they are extremely durable.
Gemstones are mined in a wide range of geological contexts. Finding and extracting them is a challenging feat and often unprofitable due to geological and engineering difficulties that are encountered in the exploration and extraction stages. A ruby of 5 grams (25 carats) can be worth several hundred thousand dollars, or practically nothing. This sets coloured gemstones apart from many other resources. Unlike gold or coffee, there are no commodity or listed prices for coloured gemstones.
Coloured gemstones can also be found in river gravels, and methods similar to the panning of gold are used to collect them.
