Are you a fan of natural gemstones and crystals? You’ll be blown away by the stunning Boulder Opal known as the ‘Rainbow Tree’ from Queensland, Australia. It’s incredible to witness the beauty of these natural pieces created by the Earth, some of which are thousands of years old and have crystallized and taken form over time. Crystals are formed by molecules in liquids hardening as they cool, and precious stones like diamonds, emeralds, and rubies are formed from magma cooling very slowly and hardening. Diamonds and quartz crystals are two of the hardest stones known to man, making them useful for creating tools like diamond saws or even record needles. Quartz is also used in watches, and you may even be able to see a little piece of quartz in your own watch! Of course, crystals and precious gems are highly desirable for crafting jewelry. We all know that diamonds are one of the most sought-after stones you can purchase, but they’re quite pricey because of how difficult they are to source.
