Where to find Faceted Gemstone
Gemstone Mines and Deposits
Faceted gemstones are sourced from various gem-producing regions worldwide. Major sources include Brazil (tourmaline, aquamarine), Colombia (emerald), Myanmar (ruby, jade), Sri Lanka (sapphire, garnet), Africa (various countries for diamond, tanzanite, garnet), and the United States (sapphire, tourmaline).
Jewelry Stores and Gem Dealers
Faceted gemstones are primarily found in commercial settings where they are sold for jewelry or collecting. These are not natural occurrences but rather points of sale for processed minerals.
Collecting tips
- Consult a Gemologist. To identify the specific mineral type of a faceted gemstone, consult a certified gemologist. They use specialized tools (refractometer, polariscope, microscope) to determine optical and physical properties.
- Examine Optical Properties. Observe the stone's brilliance (light reflected from the surface), fire (dispersion of light into spectral colors), and scintillation (flashes of light as the stone moves). These properties are enhanced by faceting and are key to gem quality.
- Consider Color and Clarity. Color (hue, tone, saturation) and clarity (absence of inclusions) are crucial factors in identifying and valuing a faceted gemstone. These are inherent to the mineral but are evaluated in the context of the cut stone.
Quick Check
- Color:
- Highly variable, depends on the specific mineral.
- Luster:
- Vitreous to adamantine, due to polishing.
- Streak:
- Not applicable for a faceted gemstone; streak is a property of the powdered mineral, which would damage the gem.
