    Solid gold is a crafted metal, made of gold alloy throughout rather than a plated or vermeil layer. Color and finish depend on the karat and the finish of the individual piece; the product photographs and measurements describe the item you will receive.

    In this piece: 10kt solid yellow, white or rose gold for the ring setting and band.

    Is it solid gold all the way through?

    Yes. Solid gold is an alloy throughout, so the metal is not a plated or vermeil layer. The karat is shown on the product page.

    Will every solid gold 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.

    Dark and solid

    A raw black obsidian beside two lab-grown diamonds

    A raw, untreated black obsidian of about 10 by 8 millimeters, with two lab-grown diamonds in solid gold.

    Anvil holds a raw, untreated black obsidian of about 10 by 8 millimeters at the front of the ring. The stone keeps its natural edges and glossy dark surface, so it reads as volcanic glass shaped by nature.

    Two round lab-grown diamonds sit beside the obsidian, about 0.06 carats in total. Each lab diamond is made in a lab with the same chemistry as a mined diamond, and their small facets send bright points of light across the dark stone.

    Anvil is made in 10kt solid gold, in yellow, white or rose. It suits tailored clothing, black knitwear and evening outfits, and its raw stone gives the ring a steady, personal character.

    Solid and steady

    A solid gold ring that sits firmly on the finger

    A 10kt solid gold ring made in sizes 5 and 7.

    The ring sits firmly on the finger, and the setting holds the raw obsidian securely so its uneven edges stay in view. The solid gold band feels substantial and keeps the stones level through the day.

    Yellow gold gives a warm frame to the dark stone, white gold gives a cool, sharp line, and rose gold brings a soft blush. The ring is made in sizes 5 and 7, so measure carefully before you order.

    The meaning of strength

    Black obsidian is often associated with strength and resilience, the steady inner resolve that helps a person keep going through a demanding stretch. A raw dark stone in solid gold is a lasting way to carry that steadiness, so Anvil suits anyone who values quiet, dependable strength. The meaning is yours to choose, and the ring makes no promise of a particular result.

    Some people give a raw obsidian ring to a friend who has taken on a demanding challenge. Others wear one as a private reminder to stay steady when the day asks more than expected.

    Choosing your size

    Sizes for this ring are 5 and 7. 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 raw stone has uneven edges, check that the ring sits flat when your hand is relaxed and does not rock. If you are between the two sizes, choose the one that moves over the knuckle with slight resistance.

    Caring for the raw stone and gold

    Black obsidian can chip under hard knocks, and chlorine, lotion, perfume and sweat can dull its gloss and the gold. 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 raw edges, the lab diamonds and the solid gold.

    Frequently asked questions

    Is the black obsidian natural?

    Yes. Black obsidian is a natural volcanic glass, and this stone is raw and untreated, so its edges and surface are left as they formed.

    Are the lab diamonds natural?

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

    What ring sizes are available?

    Sizes 5 and 7 are available for this ring. Measure your finger before you order.

    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.

    Is the ring solid gold?

    Yes. The ring is made in 10kt solid gold in your chosen colour, not plated or vermeil.

    Does the ring promise any effect?

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

    Can I wear it in the shower or pool?

    Please remove it before swimming, showering or exercise. Chlorine, lotion and sweat can dull the obsidian and the gold.

    How should I clean it?

    Wipe gently with a soft dry cloth. Avoid harsh polishes and ultrasonic cleaners, which can damage the raw obsidian and loosen the small lab diamonds.
