My Buying Guides on ‘Black Onyx Necklace Mens’
When I decided to buy a black onyx necklace for myself, I quickly realized there’s more to consider than just picking a stylish piece. Here’s what I learned along the way, and what I think you should keep in mind when choosing the perfect black onyx necklace for men.
Understanding Black Onyx
First, I made sure I understood what black onyx really is. It’s a type of chalcedony quartz known for its deep, solid black color, often polished to a glossy finish. This gemstone is believed to have protective and grounding properties, which added a personal meaning for me beyond just aesthetics.
Choosing the Right Necklace Style
Black onyx necklaces come in various styles, and I found it important to pick one that fits my personality and daily wear needs. Some popular styles include:
- Pendant Necklaces: A single black onyx stone set in silver or stainless steel, which gives a classic and versatile look.
- Beaded Necklaces: Strung black onyx beads create a bold statement and a more casual vibe.
- Chain Necklaces with Onyx Accents: These combine metal chains with onyx elements for a modern edge.
Think about whether you want something subtle or a piece that stands out.
Material and Craftsmanship
The metal used alongside the black onyx can make a big difference. I preferred sterling silver and stainless steel for their durability and style. Gold options are available but tend to be pricier. Also, I checked the craftsmanship carefully—well-cut onyx stones and secure settings meant the necklace would last and look great over time.
Size and Length Considerations
Necklace length can change the entire look. I measured my neck and thought about where I wanted the necklace to sit. Men’s black onyx necklaces typically range from 18 to 24 inches. A shorter length sits near the collarbone, while a longer chain can look more casual or rugged.
Authenticity and Quality
It was important for me to confirm that the black onyx was genuine. Some sellers offer treated or dyed stones, which can affect quality and price. I looked for reputable brands or jewelers and asked about return policies and certifications if available.
Budget and Value
Black onyx necklaces can vary widely in price. I set a budget that balanced quality and style without overspending. Remember, a higher price often means better materials and craftsmanship, but there are affordable options that still look fantastic.
Personal Style and Occasion
Finally, I thought about how the necklace would fit into my wardrobe and lifestyle. Was I buying it for daily wear, special occasions, or as a meaningful gift? This helped me narrow down my choices and pick a necklace that truly matched my personal style.
