What is demi-fine jewelry?
Demi-fine jewelry sits between inexpensive costume jewelry and solid precious-metal fine jewelry. The term is not a regulated material standard, so it can describe sterling silver, vermeil, stainless steel, or other bases with a gold finish. Always read the actual base and coating specification.
Is demi-fine a legal quality grade?
No. Unlike a karat mark, demi-fine does not define a gold percentage, coating thickness, base metal, or test method. Two products using the label may have entirely different construction and durability.
How is it different from costume jewelry?
The distinction is usually positioning, materials, and price rather than a universal rule. A useful product page names the base, finish, post material, return policy, and care expectations instead of relying on the category label.
Where does stainless-steel PVD jewelry fit?
Stainless steel with an 18K gold PVD finish is often sold as demi-fine or waterproof jewelry. Siafra prefers to state the construction directly: stainless steel rather than brass, an 18K gold PVD finish, and steel earring posts rather than plated ones.
