    Black Obsidian

    Black Obsidian
    • Black Obsidian texture
    • Black Obsidian tone
    • Personal meaning

    Representative material visualization · Appearance may vary

    Black Obsidian is a natural material selected for its slate visual character. Surface, color and pattern can vary with the cut, finish and individual piece; the product photographs and measurements describe the item you will receive.

    In this piece: marquise and oval black obsidian, about 4 by 2 millimeters, as the dark main stones.

    What does black obsidian symbolize?

    In crystal and jewelry traditions, black obsidian is associated with reflection, intention and personal style. These meanings are cultural and personal; they are not medical benefits or promises.

    Will every black obsidian piece look the same?

    No. Variation can come from the material, cut, finish and lighting. Use the individual product photographs and measurements to judge the piece you will receive.

    How should I care for it?

    Keep finished jewelry away from hard impacts, harsh chemicals and abrasive cleaners. Follow the product-specific care instructions, including those for metal finishes and other components.

    Labradorite

    Labradorite
    • Changing reflections
    • Stone variation
    • Personal meaning

    Representative material visualization · Appearance may vary

    Labradorite adds a darker contrast to jewelry, with reflections that can change as the stone and light move. Color and the visibility of that effect vary; each product supplies its own shape and setting details.

    In this piece: a round labradorite set beside the black obsidian. Each labradorite is one of a kind.

    Will the reflections always look blue?

    No. The visible reflection depends on the individual stone, lighting and viewing angle. A reference image does not guarantee a specific color or intensity in every piece.

    What does labradorite symbolize?

    In crystal traditions labradorite is associated with change and personal reflection. Such meanings are symbolic, not evidence of medical effects, protection or guaranteed results.

    How should I care for it?

    Protect the finished piece from hard impacts, heat, abrasive cleaners and chemicals. Follow its product care instructions, particularly when it also includes pearls or a plated metal finish.

    Representative material visualization · Appearance may vary

    A lab-grown diamond is a crafted material with the same optical and physical properties as a mined diamond. Its brilliance and cut vary with the individual stone; the product photographs and measurements describe the item you will receive.

    In this piece: a round lab diamond set in the band with the other stones.

    Is a lab diamond the same as a mined diamond?

    A lab-grown diamond has the same optical and physical properties as a mined diamond. It is grouped here as a crafted material because it is grown in a lab.

    Will every lab diamond piece look the same?

    No. Variation comes from the material, cut, finish and lighting. Use the individual product photographs and measurements to judge the piece you will receive.

    How should I care for it?

    Keep finished jewelry away from hard impacts, harsh chemicals and abrasive cleaners. Follow the product-specific care instructions, including those for metal finishes and other components.

    Sterling Silver

    Sterling Silver
    • 925 silver
    • Silver alloy
    • Gentle care

    Representative material visualization · Appearance may vary

    Sterling silver is a silver alloy used in jewelry. Its bright, cool-toned surface can develop a natural patina with wear and exposure. The visible finish may also be plated, so always check the metal option for the individual piece.

    In this piece: 925 sterling silver, or 18kt gold vermeil over sterling silver, for the ring setting and band.

    Is sterling silver the same as a silver-colored finish?

    No. A silver-colored appearance alone does not establish metal content. Use the product's confirmed material specification; never identify sterling silver from its color or a reference photograph.

    Can sterling silver have a gold-colored finish?

    Yes. A gold layer can be applied over a sterling-silver base. In a vermeil option, the base metal and surface finish should both be stated; it must not be described as solid gold.

    How should I care for the finish?

    Store jewelry dry and separately, avoid cosmetics and household chemicals, and use a soft cloth. Follow the product's own care instructions before using silver cleaner, especially when stones, thread or gold plating are present.

    Crystal meanings are shared as traditional symbolism for personal reflection. They are not medical, financial, or professional advice, and they do not guarantee an outcome.

    Dark and steady

    Black obsidian set with a labradorite flash

    Marquise and oval black obsidian of about 4 by 2 millimeters, with a round labradorite and lab diamond.

    Bastion sets marquise and oval black obsidian of about 4 by 2 millimeters across the front of the ring. Black obsidian is a volcanic glass with a clean, glossy face, and the dark stones read as a steady line of color across the finger. Beside them a round labradorite holds a blue, gray and teal flash that moves as the hand turns.

    A round lab diamond sits in the band with the other stones. The lab diamond is grown in a lab with the same chemistry as a mined diamond, and it adds a small, bright point to the dark base. The shapes are small and close together, so the ring reads as one tidy design rather than a set of separate stones.

    The total stone weight is about 0.49 carats, so the ring stays light and easy to wear. Bastion suits dark knits, tailored jackets and everyday clothes in black and gray, and it adds a focused accent that does not need to be loud.

    Firm and well made

    A band that holds its line on the finger

    About 1.50 grams of metal in a ring with a firm, even setting.

    The ring weighs about 1.50 grams, so it feels solid without being heavy. The setting is kept low and even, so the stones sit flat against the finger and do not catch on sleeves or gloves in a busy day.

    Sterling silver gives the band a sharp, cool edge that suits silver jewelry and dark clothes. Yellow gold vermeil adds a warm golden edge that complements the obsidian and sits well with earthy tones and gold accessories.

    The meaning of strength

    Black obsidian is often associated with strength and grounding, a steady presence that helps a person stay centered through a demanding stretch. Its dark, smooth face has long been linked with resilience and quiet determination, so Bastion suits anyone who values steadiness. The meaning is yours to choose, and the ring makes no promise of a particular result.

    Some people give a black obsidian ring to a friend who has faced a hard season and kept going. Others wear one as a private reminder to stay steady when the plan needs more time.

    Choosing your size

    Sizes run from 5 to 10. Measure a ring you already wear that fits well, or wrap a strip of paper around the base of the finger, mark where it overlaps and compare the length with a size chart.

    Because the stones are set low across the front, check that the ring sits flat and stays in place when your hand is relaxed. If you are between sizes, choose the one that moves over the knuckle with a little resistance.

    Caring for the stones and finish

    Black obsidian can chip under hard knocks, labradorite can scratch, and lotion, perfume, heat and chlorine can dull the stones and the vermeil. Remove the ring before cleaning, gardening, swimming, exercise and sleep.

    After wear, wipe the ring with a soft dry cloth and store it in a separate pouch. Keeping it apart from harder jewelry protects the stones, the lab diamond and the finish, so the dark base keeps its smooth gloss.

    Two finishes with the same black obsidian ring. Choose yellow gold vermeil for warmth or sterling silver for a sharp, cool line.

    Frequently asked questions

    Is the black obsidian natural?

    Yes. Black obsidian is a natural volcanic glass, and its gloss and tone vary a little from one stone to another.

    Is the labradorite one of a kind?

    Yes. Every labradorite is unique, so expect your own play of blue, gray, green and teal rather than an exact match to the photos.

    Are the lab diamonds natural?

    No. Lab diamonds are grown in a lab rather than mined. They share the chemistry of mined diamonds.

    Is this ring in stock now?

    The ring is sold as a standard item. Check the product page for the delivery estimate shown there before you order.

    What ring sizes are available?

    Sizes 5, 6, 7, 8, 9 and 10 are available. Measure your finger before you order.

    Are the finishes solid gold?

    No. The gold finish is 18kt yellow gold vermeil over sterling silver, a thin gold layer rather than solid gold.

    Does the ring promise any effect?

    No. Black obsidian is often associated with strength and grounding, and those meanings are yours to choose. The ring makes no promise of a particular outcome.
