Does Xonotlite Make a Good Jewelry Stone?
Despite a mid-range hardness (6), which makes xonotlites somewhat vulnerable to scratches, these gems have greater resistance to blows than most jewelry stones. They have a "tough" tenacity, while most gemstones only rank as "brittle." Nevertheless, you're more likely to find these stones in mineral collections than in jewelry collections.
Lapidaries have cut translucent (not truly transparent) faceted stones up to several carats in size from Italian material.
Are There Synthetic Xonotlites?
Researchers have synthesized xonotlite via the hydrothermal method. The synthetic material has been used in powder form for industrial purposes, such as absorption, insulation, and pigment extension. However, no jewelry use for this material is known.
There are no known treatments or enhancements for xonotlites.
Where is Xonotlite Found?
Mexico and the Vicenza region of Italy have produced gem-quality, facetable material.
- Tetela de Xonotla, Mexico.
- Laghi di Posina, Vicenza, Italy.
Other notable sources include the following:
- United States: California; Michigan; Puerto Rico; Virginia.
