Obsidian is a type of glass—specifically, natural volcanic glass. However, when it breaks, it forms an edge that is significantly sharper than manufactured man-made glass.
Not all obsidian is of high enough quality to hold a fine edge. Sometimes the lava has too many crystals or bubbles and it breaks less reliably. Some specialty glass might be sharper than some obsidian. Hard to say for sure.
In crystal healing and spiritual practices, black obsidian is considered an intense, powerful grounding stone. Due to its strong energy, those seeking a gentle experience, individuals with unprocessed emotional trauma, and people highly sensitive to heavy or intense vibrations may want to avoid or limit wearing it.
Surgeons do not commonly use obsidian scalpels because the volcanic glass is highly brittle and can leave microscopic, unsterilizable fragments inside a patient's wound. While incredibly sharp, obsidian must be handmade through knapping, making these blades significantly more expensive and difficult to standardize than mass-produced steel.
Obsidian typically costs between $𝟐 and $𝟑𝟎 per pound, depending on the quality, type, and size of the stones. Common, rough black obsidian used for rock tumbling or knapping is the most affordable, while rare varieties like rainbow, gold-sheen, or large specimen pieces fetch a higher premium.
The Warner Mountains are famous for the variety of obsidian and for the four mines where the public can, with a permit, collect it. The four mines - Pink Lady, Lassen Creek Rainbow, Needles, and Middle Fork Davis Creek - are all located within a few miles of US Hwy 395 in northeast California.
Fire obsidian is the rarest and most valuable color variety of obsidian. Unlike standard black obsidian, it features vivid, iridescent, rainbow-like colors. These metallic flashes are caused by incredibly thin, natural layers of magnetite nanoparticles trapped within the volcanic glass.
In crystal healing and spiritual traditions, Black Obsidian is believed to be a highly grounding but intense stone that acts as a mirror to the soul. Because it draws out deep, hidden emotions, certain people are advised to avoid wearing it:
A sensor is placed on the fingertip and this measures the level of oxygen in the blood and works by passing red light through tissue. Nail polish may reduce the effectiveness of this monitor. The nail bed is one of the best places to detect cyanosis caused by low oxygen levels.
It is widely accepted that the ancient Maya practiced sacrificial bloodletting to communicate with their dead ancestors and the gods. Implements to draw blood included a variety of tools, including stone blades made of obsidian.
Obsidian is primarily associated with the zodiac signs Scorpio and Sagittarius. It is celebrated in astrology for its strong grounding, protective, and transformative energies.

Yes, your private parts are covered during surgery. Medical teams prioritize your dignity and privacy. The staff will only expose the exact area needed for the operation and will use sterile surgical drapes to cover the rest of your body.
Hospitals prohibit gel and artificial nails because they harbor high levels of bacteria and fungi, and are much harder to clean than natural nails. They pose a severe infection risk for vulnerable patients and can interfere with life-saving equipment like pulse oximeters.
Follow the instructions exactly about when to stop eating and drinking. If you don't, your procedure may be cancelled. If your doctor told you to take your medicines on the day of the procedure, take them with only a sip of water. Do not apply lotions, perfumes, deodorants, or nail polish.

Obsidian is found primarily in the western United States in areas with a history of volcanic activity. Significant deposits, accessible for rockhounding and collecting, are concentrated in Oregon, California, Utah, and New Mexico.
Rainbow obsidian is a moderately rare and highly sought-after variety of volcanic glass. While common black obsidian is abundant, the specific conditions required to form the perfect microscopic mineral inclusions (like magnetite and hedenbergite) that create the "rainbow" flash make it significantly more scarce.
Obsidian most closely resembles jet black or a very dark, cool gray. Because it is a form of volcanic glass, its deep, inky shade often reflects light with a shiny, vitreous luster.
