8 best most precious gems

Precious gems are fascinating and valuable stones that have captivated humans for centuries. These gemstones are often used in educational science kits, toys, and games to teach children and enthusiasts about their unique properties. Here are some details about some of the most precious gems:

Diamonds: Diamonds are the hardest natural substance on Earth, composed of carbon atoms arranged in a crystal lattice. They are known for their brilliance and are often used in jewelry. In educational kits, you can learn about diamond formation and the 4Cs (cut, color, clarity, and carat weight) used to grade them.
Rubies: Rubies are red gemstones, a variety of the mineral corundum. They are known for their intense color and are often associated with love and passion. Learning about rubies can involve understanding their crystal structure and the factors that influence their color.
Sapphires: Sapphires are also a variety of corundum but come in various colors, with blue being the most famous. Educational kits can teach about sapphire formation and the different colors they can exhibit due to trace elements.
Emeralds: Emeralds are a type of beryl known for their vibrant green color. They are relatively softer than other precious gems, which makes them more susceptible to damage. Learning about emeralds can involve understanding their inclusions and the treatments used to enhance their appearance.
Opals: Opals are unique gemstones known for their play-of-color, which gives them a mesmerizing appearance. Educational kits can explore the science behind this optical phenomenon and the various types of opals.
Pearls: Pearls are organic gemstones formed inside mollusk shells. Learning about pearls can involve studying the process of pearl formation, different types of pearls, and their historical significance.
Amber: Amber is fossilized tree resin and is not a mineral, but it is often included in discussions of precious gems.It can contain well-preserved ancient organisms and is used in educational kits to teach about paleontology and geology.
Tanzanite: Tanzanite is a relatively recent discovery in the world of gemstones. It is known for its striking blue or violet-blue color and is found mainly in Tanzania. Learning about tanzanite can involve understanding its geological origin and its popularity in the jewelry industry.
Aquamarine: Aquamarine is a blue or green-blue variety of beryl. It is often used in educational kits to teach about the geological processes that lead to the formation of gem deposits.
Citrine and Amethyst: These two gemstones are both varieties of quartz and can be used to illustrate the effects of impurities on a mineral's color in educational settings.

These precious gems are not only beautiful but also offer opportunities for learning about geology, mineralogy, and the science behind their unique characteristics. Educational science kits, toys, and games that focus on these gems can provide an engaging way to explore the world of gemstones and earth sciences.

User questions & answers

Question:	Made in USA
Answer:	I've worn it by accident a few times in the shower and it has not tarnished. However, I don't think it's meant to be submerged on a regular basis.
Question:	What are they made of
Answer:	I wish I could help you but if it is gold over silver it might be impossible to fix unless you take it to jeweler to redo the gold overlay. I bought the silver and it is still in great shape. So sorry you are having this problem. I know never to clean overlay items with a cleaner, just use a soft cloth and water. I know this did not help you so I am sorry about that.

Question:	How/where can I purchase the neckalce shown in the 4th photo? I would love the full set for my wedding
Answer:	This is what happened with mine. I just het the bottle instead. Contact Amazon costumer representative, they should be able to further assist.
Question:	The tag on these says: 'product of china/assembled in usa'. Are the sterling details made in china, not in US
Answer:	Not long. It smells really good going on but doesn't last long.
Question:	These are solid sterling silver with a stamp
Answer:	I bought a persian rose from a whole foods store about a year ago, and my trick was instead of rollin the ball on the skin, i'd tap it and check for the perfume by reflection from lights. It does defeat the purpose of it being a roller ball, but i still like it enough to try and get different scents~!
