    • 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: an oval brilliant black obsidian, about 8 by 10 millimeters, as the main stone.

    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.

    In this piece: a black spinel accent set beside the black obsidian.

    What does black spinel look like?

    Black spinel has a dark surface with reflective facets or a smooth polish, depending on the cut.

    What is black spinel traditionally associated with?

    In jewelry traditions, black spinel is associated with focus and considered personal style. These are cultural meanings, not promises.

    How should I care for black spinel jewelry?

    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.

    Bold oval black obsidian and black spinel ring

    Dark, deep and confident

    An oval black obsidian with a black spinel beside it

    An oval brilliant black obsidian of about 8 by 10 millimeters, with a black spinel accent.

    Bold holds an oval brilliant black obsidian of about 8 by 10 millimeters at the front of the ring. The oval outline is long and steady, and the obsidian's glossy dark face reflects light softly, so the stone looks deep and calm on the hand.

    A black spinel sits beside the obsidian and adds a second dark tone with its own quiet depth. Together the two stones carry about 2.65 carats, a size that makes a clear, confident statement without feeling heavy.

    Bold suits dark tailoring, black knitwear and evening clothes. It stands on its own as a strong single accent, or it sits with a plain band in a stack.

    A close view of the black oval stone reveals angular facets, yellow gold prongs, and round black stones along the band.

    Sharp and substantial

    A ring with a firm setting for two dark stones

    About 1.96 grams of metal in a firm setting that holds both stones securely.

    The ring weighs about 1.96 grams, a comfortable weight that feels steady on the finger. The setting holds the oval obsidian and the spinel firmly, so the stones stay level and easy to see from the front.

    Yellow gold vermeil warms the dark stones with a golden edge, rose gold vermeil gives a gentle blush, and sterling silver keeps the setting sharp and cool. Each finish suits a different style of clothing and jewelry.

    The meaning of strength

    Black obsidian is often associated with strength, the steady inner resolve that helps a person keep their footing through a demanding day. Black spinel is linked with focus, so this ring pairs two dark stones that suggest concentration and resolve together. The meaning is yours to choose, and the ring makes no promise of a particular result.

    Some people give a dark stone ring to a friend who is starting a demanding role or a long project. Others wear one for an evening when they want a bold, composed look.

    Choosing your size

    Sizes run from 4 to 11. Measure a ring you already wear that fits well, or wrap a strip of paper around the base of the finger, mark the overlap and compare the length with a size chart.

    Because the oval stone sits across the front, check that the ring settles level when your hand is relaxed. If you are between sizes, choose the one that moves over the knuckle with slight resistance.

    Caring for the obsidian and spinel

    Black obsidian can chip under hard knocks, and lotion, perfume, heat and chlorine can dull both stones and the finish. 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 obsidian, the spinel and the finish, so the dark surfaces keep their shine.

    Find your metal tone

    Three finishes with the same black obsidian and black spinel ring. Choose yellow gold vermeil for warmth, rose gold vermeil for softness or sterling silver for a cool line.
