Titanium
Offers the best strength-to-weight ratio and hypoallergenic properties, the current premium-tier standard material for smart rings positioned at a higher price point.
Stainless Steel
Costs less than titanium but weighs more, a reasonable mid-tier choice for brands prioritizing cost control over the lightest possible feel.
Ceramic Coating
Applied over a metal base rather than used structurally, ceramic coating adds scratch resistance and a distinctive matte finish, commonly used as a cosmetic upgrade layer rather than a standalone shell material.
