1. Types of Quartz: Macrocrystalline vs. Cryptocrystalline

Quartz exists in two primary forms, distinguished by crystal size:

Macrocrystalline Quartz

• Large, visible crystals
• Common forms include Amethyst, Citrine, and Smoky Quartz
• Typically transparent or translucent

Cryptocrystalline Quartz (Chalcedony Group)

• Composed of microscopic crystals
• Includes Agate, Jasper, Onyx, and Carnelian
• Usually opaque or semi-translucent

2. Common Quartz Varieties and Their Properties

Macrocrystalline Quartz Varieties

• Clear Quartz (Rock Crystal): Colorless, highly transparent, used in optics and electronics.
• Amethyst: Purple variety, popular in jewelry, believed to have calming properties.
• Citrine: Yellow to golden-orange, symbol of prosperity and energy.
• Smoky Quartz: Brown to gray, used in spiritual healing and decorative items.
• Rose Quartz: Pink variety, commonly associated with love and emotional healing.
• Milky Quartz: White and cloudy, used in carvings and industrial fillers.

Cryptocrystalline Quartz Varieties (Chalcedony Family)

• Agate: Banded multicolor quartz, used for ornamental stones and seals.
• Jasper: Opaque quartz in red, yellow, or brown, used in carvings and mosaics.
• Carnelian: Reddish-orange variety, prized for ancient seals and amulets.
• Onyx: Banded black and white, used in cameos and intaglios.
• Chrysoprase: Apple-green, rare and valuable, often used in high-end jewelry.

Synthetic Quartz

• Lab-Grown Quartz: Manufactured for consistency and purity
• Common in electronics, optics, and industrial tools

3. Industrial-Grade Quartz: Applications and Specifications

Industrial quartz differs significantly from gem-grade varieties. It’s engineered for high thermal resistance, chemical stability, and optical clarity. These properties make it essential for demanding sectors like semiconductors, photonics, and metallurgy.

Key Applications

• Laboratory Glassware: Crucibles, flasks, and beakers made of quartz can withstand extreme temperatures and corrosive chemicals.
• Semiconductor Industry: Quartz tubes and rods are used for etching, diffusion, and chemical vapor deposition (CVD).
• Optical Devices: UV and IR-grade quartz (JGS1, JGS2, JGS3) are used in lasers, lenses, and spectrometers.

Standard Grades of Quartz Glass

• JGS1: UV grade, high purity, excellent UV transmission
• JGS2: General optical quartz, suitable for visible and near-UV
• JGS3: IR grade, used for infrared applications
