Not in its raw state, but can be once refined.
Unadulterated silver nitrate is a pure substance.
Silver can be a pure substance if it is an unadulterated silver nitrate. Silver is a transition metal that is soft and white.
Pure silver is a single substance, an element. All its particles are silver atoms. That said, it is rare to encounter pure silver. For coinage and jewellery it is usually alloyed, often with copper, to make it harder.
calcium is an element, so it is the pure substance.. it is a grey/silver. calcium is an element, so it is the pure substance.. it is a grey/silver.

Mixture
Pure gold or silver are not alloys.
A silver pendant could be a pure substance, but if it is a modern commercially produced pendant, it is more likely to be a mixture, because pure silver is so soft that it is very easily damaged. The most nearly pure silver alloy commonly used in jewelry is called "sterling silver" and contains 92.5 % silver.
Silver is an elemental metal. This means unalloyed silver is pure, but most silver jewelry will alloy the silver with other metals (e.g. copper). Silver also oxidizes easily, producing silver sulfide and/or silver oxide surface films. Silver has two naturally occurring isotopes: silver-107 (51.4%) and silver-109 (48.6%).
24k Gold is a pure substance. Because it is made up of just gold unlike 14k gold which is silver and gold mixed.
No, as its name might indicate it is a compound and therefore a pure substance.
