Today, we’re diving into the fascinating world of gems with Lance Grande, a distinguished curator. Gems are not only beautiful on their own, but they also highlight human creativity through the work of designers and jewelers. Additionally, they showcase the natural beauty of crystals. Some gems are even more stunning in their natural form than when they are cut. As part of a natural history museum, it’s essential to connect these gems to the broader story of natural history.
One of the gems we’ll explore is a tourmaline with a striking emerald color, set in a Victorian-style piece made of platinum and diamonds. This piece also features diamonds and a large baroque pearl, likely set in 18-karat white gold. It’s a remarkable and sizable piece!
There’s also a special type of tourmaline called paraiba tourmaline. Tourmaline can be found in every color of the rainbow, and the color is a crucial aspect of these stones. While the chemical composition remains the same, a trace element can change the color. This is similar to diamonds, which can also come in various colors due to trace elements.
The value of gems can vary greatly. For instance, a 2-carat white diamond might cost around $10,000, but a 2-carat red diamond could be worth about $5 million due to its rarity.
Amethyst is another interesting gem. It used to be rare and expensive until large deposits were found in Brazil, which caused the prices to drop. There’s also a piece that looks like melted glass, which is actually a low-quality emerald. If it were a more vibrant green, it would be much more valuable.
Some artists specialize in carving gems, a challenging task that requires using other diamonds to carve them. We also have another paraiba tourmaline and diamond necklace, along with a jadeite necklace. The jade piece is quite heavy, similar to wearing several marbles around your neck. Jade is not only heavy but also one of the toughest gems.
Golden pearls, which come from a specific species of mollusk, are valued more than white pearls. There’s also an expensive necklace worth about a quarter of a million dollars, featuring kunzite and tsavorite garnet, one of the rarest garnets.
Imagine trying on such a beautiful piece! It’s amazing how it feels to wear something so exquisite.
Here’s a bin filled with sizable pearls in various colors, and a bag of rubies, which are essentially red sapphires. There’s also a light-colored stone that resembles a white sapphire.
Diamonds have a unique quality in how they diffract light, creating rainbows, while sapphires don’t exhibit the same brilliance.
We also have gold nuggets, with one weighing about 12 ounces. Gold is currently valued at around $13,000 an ounce. Crystalline gold is rare, and most raw gold appears as dust or nuggets.
Here’s a diamond in its natural, uncut form, showing how it looks before being polished. There’s also a historic coin made in Russia when platinum was less valuable than gold.
This is a selenite crystal, a natural beauty, and here’s a piece of boulder opal. The rarest colors in opal are red, while blue and green are more common.
This butterfly pin is made of gold, diamonds, rubies, and jadeite. It’s quite heavy and would be perfect for an elegant occasion.
Here’s a large blue topaz, impressive in size, and a beautiful aquamarine crystal, which could yield sizable stones if cut.
These are red garnets, which form in a unique way, and here’s a rose quartz bowl carved from a single piece.
Lastly, here’s a crystal ball made of clear quartz. Can you tell my fortune? I think you’re going to be on YouTube!
Explore the different types of gems mentioned in the article. Create a chart that lists each gem, its unique characteristics, and its value. Then, test your knowledge by identifying gems based on their descriptions. This will help you understand the diversity and beauty of gems.
Conduct a simple experiment to understand how trace elements affect the color of gems. Use food coloring and water to simulate how different elements can change the appearance of a gem. Document your findings and present them to the class.
Using the information about gem settings and styles, design your own piece of jewelry. Draw your design and explain the choice of gems and materials. Consider how the color and type of gem can influence the overall aesthetic and value of the piece.
Participate in a debate about what makes a gem valuable. Consider factors such as rarity, color, size, and historical significance. Use examples from the article to support your arguments and engage in a lively discussion with your classmates.
Create a virtual tour of a gem museum using digital tools. Include descriptions and images of the gems discussed in the article. Share your tour with the class and highlight the most fascinating aspects of each gem, connecting them to their natural history.

Today we’re going to explore the gem room with Lance Grande, the distinguished service curator. Like my position, there’s only one! I’m also the curator of gems by default, which is the connection there.
We’re going to look at gems today. They’re beautiful on their own, but they also showcase human artistry through the designers’ work and jewelry, as well as natural beauty in their crystal forms. Some of these stones are even more appealing in their natural state than after they’ve been cut. Since we are a natural history museum, it’s important to connect these gems to natural history.
This stone is a beautiful emerald-colored tourmaline, set in a Victorian setting of platinum and diamonds. This piece features diamonds and a large baroque pearl, likely set in 18-karat white gold. It’s stunning and quite large!
This is a paraiba tourmaline, a special type of tourmaline. Tourmaline comes in every color of the rainbow, and the color is crucial for these stones. The chemical composition is the same; the only difference is a trace element that alters the color. The same applies to diamonds, which can be found in various colors due to trace elements.
The differences in value can be astounding. For example, a 2-carat white diamond might be around $10,000, while a 2-carat red diamond could cost about $5 million due to its rarity.
This is an amethyst, which used to be very rare and expensive until large deposits were discovered in Brazil, causing prices to drop. Here’s an interesting piece that looks like melted glass; it’s actually a low-quality emerald. If it were a prettier green, it would be much more valuable.
Some artists specialize in carving gems, which is quite challenging because they must use other diamonds to carve them. Here’s another paraiba tourmaline and diamond necklace, along with a jadeite necklace. This jade piece is quite heavy, comparable to wearing several marbles around your neck. Jade is not only heavy but also one of the toughest gems.
These are golden pearls, which come from a specific species of mollusk and are valued more than white pearls. Now, here’s an expensive piece—a necklace worth about a quarter of a million dollars, featuring kunzite and tsavorite garnet, one of the rarest garnets.
Would you like to try it on? You look fantastic! It’s amazing how it feels to wear such a beautiful piece.
Here’s a bin filled with sizable pearls in various colors. And here’s a bag of rubies, which are essentially red sapphires. There’s also a light-colored stone that resembles a white sapphire.
Diamonds have a unique quality in how they diffract light, creating rainbows, while sapphires don’t exhibit that same brilliance.
We also have gold nuggets, and this one weighs about 12 ounces. Gold is currently valued at around $13,000 an ounce. Crystalline gold is rare, and most raw gold appears as dust or nuggets.
Here’s a diamond in its natural, uncut form, showcasing how it looks before being polished. This coin was made in Russia when platinum was less valuable than gold, making it a historic piece.
