Broke a rock we found curious in our stockpile and Broke a rock we found curious in our stockpile and found that it has garnets inside it... 🥰 Amazing!
Turquoise is an opaque, blue-to-green mineral that Turquoise is an opaque, blue-to-green mineral that is a hydrous phosphate of copper and aluminium, with the chemical formula CuAl 6(PO 4) 4(OH) 8·4H 2O. It is rare and valuable in finer grades and has been prized as a gemstone for millennia due to its hue. Turquoise gemstone set in 925 Sterling Silver. Turquoise is one of the December birthstones.
✨ Howlite – A white stone streaked with gray veins ✨ Howlite – A white stone streaked with gray veins, Howlite is a borate mineral composed of calcium, boron, silicon, oxygen, and water (Ca₂B₅SiO₉(OH)₅·H₂O).
Gem silica is desert lightning captured in stone. Gem silica is desert lightning captured in stone. At its heart it’s SiO₂ — pure silicon and oxygen woven into translucent chalcedony. But then copper slips in — Cu²⁺ — and suddenly the stone ignites in electric blues and lagoon greens. Silicon builds the crystal. Oxygen holds the lattice. Copper paints the sky inside it. Simple chemistry. Magnificent color. 💫
Sodalite is the night sky carved into stone. Deep Sodalite is the night sky carved into stone. Deep royal blue streaked with white like drifting clouds — and under UV light, it can burst into a fiery orange glow, as if it’s hiding a secret sunrise inside. Calm in daylight. Electric in the dark. ✨ Sodalite has a beautifully structured and unusual chemistry. 🧪 Chemical Formula Na₈(Al₆Si₆O₂₄)Cl₂ Let’s break that down: Na = Sodium Al = Aluminum Si = Silicon O = Oxygen Cl = Chlorine Sodalite belongs to the feldspathoid group. It forms a framework of aluminum and silicon tetrahedra (AlO₄ and SiO₄) linked together in a cage-like structure. Inside those cages: Sodium ions sit for balance. Chloride ions are trapped — which is unusual for silicate minerals. That trapped chlorine is part of what makes sodalite special.
Jasper in its autumn variety looks like the earth Jasper in its autumn variety looks like the earth decided to paint with fire. Burnt orange, golden yellow, deep rust and forest brown swirl together like falling leaves caught in sunlight. The autumn tones (reds, yellows, browns, oranges) come from iron impurities: Iron oxides (Fe³⁺) → red and rust tones (like hematite) Hydrated iron oxides → yellow to golden hues (like goethite/limonite) Even tiny amounts of iron can dramatically change the color. In Simple Terms: Autumn Jasper = Silicon dioxide + iron + time + pressure Chemically minimal. Geologically poetic. 🍂🔥🥰

Labradorite doesn’t just shine — it awakens. Tilt Labradorite doesn’t just shine — it awakens. Tilt it slightly, and a hidden universe flashes to life: electric blues, molten gold, deep forest greens — light trapped inside stone. This breathtaking phenomenon, called labradorescence, is caused by microscopic layers inside the crystal that scatter light like a prism. It looks like the Northern Lights frozen in rock ✨ A dark, ordinary surface… Until the light hits it — and magic answers.
I can play with the UV LIGHT on Nepheline Syenite I can play with the UV LIGHT on Nepheline Syenite all day... 🥰 CHATGPT: If your Nepheline syenite glows orange under UV light, the most likely minerals causing it are: 🥇 Most Common Cause: Sodalite Very common in nepheline syenite. Under UV (especially shortwave), it often fluoresces bright orange. Even small patches can make the whole rock appear to glow. 🥈 Also Possible: Calcite Frequently fluoresces orange to reddish-orange. Often appears in thin veins or small white patches inside the rock. Which one do you say it is? CALCITE 🤍 OR SODALITE 💙?

17 Important things to know before visiting China
I had a 12-hour layover to see if it’s still the same city I remember. Spoiler alert: It’s even better, though the tropical heat and humidity are just as intense as ever! I haven’t been to Singapore in 26 years, and let me tell you—the city has transformed into something out of a sci-fi movie! In this vlog, I’m maximizing every minute of my Singapore layover. I started my morning at the iconic Gardens by the Bay, wandering through the Supertree Grove before the midday sun hit. After exploring the city, I headed to Chinatown, where I was lucky enough to catch a traditional Lion Dance performance—a beautiful reminder of the culture that stays strong amidst all the new skyscrapers. As the sun went down, I headed back to the water to see the Merlion at night and caught the stunning evening light show at the Gardens. If you have a long layover in Singapore, this is how you see the best of the city in one day!

Singapore: Was Leaving Changi Airport a Mistake?
Be amazed as you see what it takes to turn raw, rugged rock into perfectly smooth, glass-like gemstones? In this video, we take you behind the scenes of a massive industrial lapidary operation to show you the exact journey of African Tiger's Eye from the crusher to the final polished product! Here is the step-by-step breakdown of how we process these incredible minerals: * *The Big Crush:* We start at the industrial crusher, breaking down a massive *20 tons of raw Tiger's Eye* into smaller, manageable sizes. * *The 1.5-Ton Tumbler:* Using a forklift, the crushed stone is loaded into a huge *1.5-ton rotating barrel tumbler* along with silicon carbide grit. This beast runs continuously for *7 to 14 days* just to smooth down the sharpest edges! * *The Deep Clean:* The stones are transferred to massive, modified cement mixers to be thoroughly washed *3 separate times*. * *First Quality Control:* The washed stones hit the sorting tables, where the human eye takes over to hand-sort and discard any flawed material. Only the best stones make the cut. * *The Fine Polish:* The selected high-quality material moves into vibrating tumblers—loaded with *600 kg* of stone each—where they run for another full week until they achieve a brilliant shine. * *Final Inspection & Lock-In:* After one last wash, every single tumble is hand-checked a second time to ensure perfection. Finally, a light waxing treatment is applied to lock in that deep, signature Tiger's Eye flash forever. ### 💬 Let's Chat! Let me know if you like this video!

Tumbling 12,500 kg of Raw Tigers Eye!
Is it a brilliant business move, or an absolute gamble? 🤔 In this video, I’m taking you back to the exact same yard where I previously sourced 14 tons of rock. This time, I committed to something completely different: acquiring approximately 130 unique gemstone spheres from a factory that just closed down. With an already packed shop, why did I do it? Because every single one of these spheres is a unique geological happening. From incredible banding to rare mineral inclusions, no two are exactly alike. Watch as I wrap, transport, and try to solve a massive logistical puzzle back at the shop. After a serious amount of shuffling and rearranging, I’ve managed to free up enough space to get about two-thirds of them onto the shelves. Will they sell? Will I make a profit? It’s hard to tell, but the sheer beauty of these pieces made it impossible to walk away. If you are nearby, you’ll have to come visit the shop in person to see them on the shelves and find out which one is your absolute favorite! Which sphere caught your eye the most in today's video? Let me know in the comments below! 👇

A futuristic treat in the heart of Guangzhou! Today we are walking down the famous Beijing Road (Beijing Walking Street) on a hunt for authentic Chinese street food, but we stumbled across something completely unexpected—a fully automated robot ice cream kiosk! For just ¥9.90, this robotic arm handles the entire process, scooping and serving up soft-serve ice cream right on the bustling night market street. Is it just a high-tech novelty, or is the ice cream actually good? Watch to see the full taste test! Beijing Road is famous for its vibrant evening atmosphere, incredible shopping, and endless rows of traditional local snacks, but seeing this level of automation blended right into the local street food culture shows just how futuristic modern China really is. Have you ever had food made entirely by a robot? Let me know in the comments below!

In today’s video, we are jumping on the Guangzhou metro from Liwan Plaza and heading straight to the bustling Taikang Fashion Jewelry Mall! While Taikang Mall is famous for massive floors of alloy-based fashion jewelry and sparkling Cubic Zirconia (CZ), we are on a very specific mission today. We aren't buying the standard fashion pieces—instead, we are heading straight up to the 4th floor to hunt down high-quality, durable stainless steel jewelry and bulk chain for Silver Hills Gems back in South Africa! Join me for a fast-paced, authentic walkthrough of the vibrant stalls, a sneak peek at the incredible variety on offer, and a look at what it’s really like to navigate one of Guangzhou's premier accessory hubs.
