This gem quality material is not commercially mined in Alaska and is increasingly rare, difficult to find, and highly sought after by gem collectors. The production from the Kennecott Mine is considered the finest quality Star of Alaska in the world because it was found in large, pure, massive pieces. The mine, which opened in 1906, closed permanently in 1938, making the gems scarce. For years, the stones for the original pieces were in a private estate. Rosemary continues to work with Alaskan rock and mineral collectors to source this amazing mineral.
For those looking for a piece of jewelry that beautifully captures the wonders of the wide open Alaskan skiy and expansive wilderness, the Star of Alaska is perfect: intense beauty, rare quality, and locally sourced.
Look for the registered *A* stamp on the back of each fine piece, your assurance of authentic Star of Alaska fine jewelry.

Karat vs. Carat
The term carat, spelledwith a "c," is often confused with the term karat. They are bothpronounced the same, but carat refers to the weight of a gemstone. You couldhave a 1.5 carat diamond set in an 18 karat gold setting.
The karat system is usedto measure the amount of pure gold found in solid gold jewelry. In the US,numbers are associated with the percentage of pure gold in a piece.
Solid Gold vs. Pure Gold
The phrase "solidgold jewelry" is a misnomer because, most times, this jewelry is not madeup of solid gold. This term references jewelry that has a gold alloy throughoutthe entire piece.
On the other hand, thephrase "pure gold jewelry" is used to describe jewelry that is madeup entirely of gold with little to no alloys present.
How a Gold Alloy isFormed
A portion of the gold ismixed with different alloys or metals, which creates a specific formula. Eachgold color, like white gold or rose gold, uses a different combination ofalloys.
Karat Used in CostumeJewelry
The term karat is alsoused on gold filled and gold plated jewelry. Even though these piecesare not solid gold, the gold portion of the jewelry has a certain percentage ofpure gold designated through karats.
Expert Tip: If yourpiece of jewelry is marked 14KGF or 10KGF, that is a common indication that theitem is gold filled and is not solid gold. However, the marking 14KP or 14KPdoes not necessarily mean gold plated. It also can stand for 14K gold plumb,which is solid gold.
If your piece of jewelryhas a P in the marking, be sure to have the gold tested.
