Hydrothermal Quartz is a lab-grown gemstone created through a high-pressure, high-temperature process that replicates natural quartz formation. Known for its clarity, durability, and availability in a wide range of colors, hydrothermal quartz is a versatile and affordable option for gem cutters and jewelry designers.

🔬 Composition & Properties

Hydrothermal quartz is composed of silicon dioxide (SiO₂), just like natural quartz. It’s grown in autoclaves using nutrient-rich solutions and seed crystals to produce flawless, consistent material. It’s known for:

• Mohs Hardness: ~7
• Refractive Index: Moderate, for clean brilliance
• Polishability: Excellent, with a smooth, glossy finish
• Color Range: Clear, amethyst, citrine, smoky, rose, and more
• Clarity: Typically high, with minimal inclusions

Each piece of hydrothermal quartz rough is suitable for faceting, cabbing, or carving, and performs well under standard lapidary techniques.

💎 Why Choose Hydrothermal Quartz?

• Natural-Like Appearance: Mimics the beauty of natural quartz
• Color Variety: Available in both classic and vibrant hues
• Consistent Quality: Reliable clarity and structure
• Cost-Effective: Affordable and eco-friendly alternative

Whether you're crafting colorful jewelry or practicing precision cuts, hydrothermal quartz offers a dependable and beautiful medium for your work.
