Quartz-rich hydrothermal mineral specimen, possibly vanadinite-bearing matrix

Quartz (SiO₂) with unidentified red-brown accessory minerals; exact species requires testing

AI-generated identification · may be incorrect

White to gray granular quartz with sparkling drusy crystals and red-brown botryoidal or granular coatings. Quartz has Mohs hardness 7, vitreous luster, hexagonal crystal structure, no cleavage, and specific gravity about 2.65; the red minerals may be softer lead, iron, or manganese minerals.

Common name: Quartz-rich hydrothermal mineral specimen, possibly vanadinite-bearing matrix
Scientific name: Quartz (SiO₂) with unidentified red-brown accessory minerals; exact species requires testing
Category: mineral
Identified: August 23, 2026
Method: Standard

AI Estimated Value

Approximately $15–$100 for a common hand specimen; $150–$500+ if the red mineral is confirmed and crystals are unusually sharp or from a desirable locality.

Physical properties

Formation & geological history

Likely formed in a hydrothermal vein or cavity where silica-rich fluids deposited quartz and later oxidized metal minerals. The specimen’s geological age cannot be determined from the image; similar assemblages occur in mineralized veins of many ages.

Uses & applications

Primarily a collector specimen and display piece; quartz is widely used in glass, electronics, abrasives, and construction, while some red associated minerals are ore minerals.

Geological facts

The red material cannot be identified reliably from appearance alone and could include iron oxides, hematite, jasper, or vanadinite-like minerals. Acid testing, streak, hardness, crystal form, and ideally X-ray diffraction or chemical analysis are needed.

Field identification & locations

Inspect for hexagonal quartz points, red streak, crystal habit, and hardness; avoid assuming the red zones are vanadinite without locality information. Commonly similar specimens come from oxidized metal deposits in the western United States, Mexico, Morocco, and Namibia.
