Variscite Rough Value Guide

This pre-1900s Variscite Rough is a significant mineral specimen prized for its distinct hydrated aluminum phosphate composition and vibrant green hues. Originally discovered in 1837, these United States-sourced pieces are highly collectible due to their historical use in ancient ornamental beads and their striking resemblance to high-grade turquoise.

What Is Variscite Rough Worth?

The typical price range for Variscite Rough is $50 - $70 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Intensity and saturation of the green coloration, with vivid apple-green being the most desirable.
• The presence and pattern of matrix inclusions, which can either enhance or detract from the aesthetic value.
• Overall specimen size and weight, specifically within the $50-$70 price bracket for standard rough pieces.
• Historical provenance and the quality of the natural, uncut surfaces from pre-1900s US deposits.

How to Identify Variscite Rough?

• Look for the characteristic waxy to vitreous luster that distinguishes natural variscite from duller imitations.
• Examine the specimen for a range of green shades, typically lacking the blue tones found in most turquoise varieties.
• Verify the hardness; variscite ranks at 4.5 on the Mohs scale, making it slightly softer than turquoise.
• Check for a white streak when tested on an unglazed porcelain plate, a key diagnostic feature of this mineral.

History of Variscite Rough

Variscite is a hydrated aluminum phosphate mineral, often confused with turquoise due to its similar appearance. It was first described in 1837 and named after Variscia, the historical name of Vogtland in Germany, where it was first discovered. Historically, it has been used by ancient cultures for ornamental purposes, often carved into beads or small statues due to its pleasing green hues.
