I bought the Onyx pendant and we can't be happier with it. The concept is amazing and heartfelt and the wearer is thrilled! Amazing quality.

Why Black Onyx Jewelry Makes a Statement That Lasts
That grounding energy makes black onyx jewelry an ideal match for personalized pieces. Each black onyx necklace and bracelet in this collection features our Eclipse Bezel setting, where a crescent moon cut-out reveals the dark stone beneath a hand-engraved star map or zodiac constellation. You choose the date, and we capture the exact arrangement of stars from that moment. A date that changed everything, a person who steadied you, or a milestone that proved your strength.
The contrast between the deep black onyx and the precision-engraved metal is striking. In sterling silver, the combination is sharp and modern, with cool tones that complement the stone's intensity. In 18k gold vermeil, it takes on a bolder, more luxurious feel. Both options suit a wide range of styles, which is one reason black onyx jewelry remains popular across all genders and ages. A black onyx necklace looks equally at home on a man as it does on a woman, and a black onyx bracelet transitions effortlessly from casual to formal.
What makes these pieces different from other black onyx jewelry on the market is the personalization. The star map or zodiac engraving transforms a beautiful stone into something with a story. It is not just bold. It is yours.
Black onyx has always carried weight. Not just physical weight, but symbolic. For centuries it has been worn as a stone of strength, stability, and quiet protection. Its deep, opaque black surface absorbs light rather than reflecting it, creating a presence that feels grounded and intentional. In crystal traditions, black onyx meaning centers on shielding against negativity and helping the wearer stay calm under pressure.
The Night Sky also offers standalone black onyx bezel pieces beyond the Eclipse collection, including the Star Map Black Onyx Bezel Necklace and Star Map Black Onyx Bezel Bracelet, as well as the larger 15mm Vermeil Bezel Necklace for those who want a more prominent statement piece.
A Black Onyx Pendant Built for Everyday Wear
Black onyx scores 6.5 to 7 on the Mohs hardness scale, making it one of the more resilient gemstones for daily wear. A black onyx pendant from The Night Sky is built to be worn constantly, not tucked away in a drawer. Its deep, rich surface does not fade or lose its depth, and the engraved star map above it only becomes more meaningful over time. This is jewelry designed to be lived in.

Is black onyx good for men's jewelry?

How do I care for black onyx jewelry?
Black onyx is relatively durable, scoring 6.5 to 7 on the Mohs hardness scale. Clean it with a soft cloth and lukewarm soapy water, then dry thoroughly. Avoid exposing it to harsh chemicals, ultrasonic cleaners, or extreme temperature changes. Store your black onyx jewelry separately from harder stones like diamonds or sapphires to prevent surface scratching.
What is the difference between black onyx and regular onyx?
Onyx is a banded variety of chalcedony that naturally occurs in several colors, including black, brown, white, and red. 'Black onyx' refers specifically to the solid black variety, which is the most widely used in jewelry. Most black onyx on the market has been treated or dyed to achieve its uniform deep black color, which is standard practice and does not affect the stone's durability or beauty.
