The Siege 10mm Cobalt Ring: Frequently Asked Questions
1. Can this cobalt chrome ring be resized?
Generally, no. Cobalt chrome is so hard that most traditional jewelry shops do not have the equipment to resize it. However, JustMensRings offers a 30-day money-back guarantee and a Lifetime Warranty that includes sizing assistance. It is highly recommended to have your finger sized with a "comfort-fit" sizer before ordering.
2. Are the diamonds in this ring real?
Yes. The Siege features three round burnished diamonds with a total weight of 0.18 carats. These are authentic stones designed to provide a brilliant contrast against the polished cobalt chrome.
3. Will the vertical grooves catch on my clothes or hair?
No. The designer uses a "burnish-set" technique for the diamonds and a high-polish finish for the grooves. This ensures all edges are smooth and flush, making it a "snag-free" design perfect for everyday wear.
4. Can I have this ring engraved?
Yes, but it requires laser engraving. Because cobalt chrome is harder than standard steel engraving tools, a high-powered laser is used to etch the metal. This results in a bold, permanent inscription on the inside of the band.
5. Is cobalt chrome safe for an MRI or in an emergency?
While cobalt chrome is extremely strong, it can be removed in a medical emergency using standard high-speed ring cutters found in most hospitals and fire departments. It is also non-magnetic and widely used in medical implants, though you should always follow your doctor's specific instructions regarding jewelry during an MRI.
