Enjoy a piece of Alaskan history with a gift for yourself or loved one!
Did you know that Alaska was once home to vibrant tropical ocean life, including sea coral?
Alaska’s Sea Coral once flourished in the warm ocean waters of the North 400 million years ago, becoming extinct with the abrupt cooling of the earth at the end of the Devonian Period. The fossilized coral is harvested today from ancient, non-viable coral beds and is among the world’s most rare. Showcased in jewelry creations, this exquisite gemstone expresses the mysterious depths of Alaska’s ancient oceans.
One-of-a-kind. Includes a certificate of authenticity.
Jewelry designed by local artist Rosemary Libert, who lives in Skagway, Alaska.
All pieces of sea coral are hand-cut to fit the jewelry design then properly shined using 6 different jewelry polishing wheels. Because fossilized sea coral found in nature is rare and one-of-a-kind you will receive the product pictured with very slight variations in veining. All jewelry is backed by the manufacturer.

Karat Definition and Guide
Karat values range from 24K down to 9K. The gold content on anything 8K or less is so low that it wouldn't be considered solid gold jewelry.
Technically you should never depend solely on a gold hallmark to determine gold value. Some people will illegally mark plated gold with 14K gold stampings to try to sell for a profit.
Ranges of Karat Values
24 karat (24K) gold is pure gold
18 karat (18K) gold contains 18 parts gold and 6 parts another metal or metals, making it 75% gold
14 karat (14K) gold contains 14 parts gold and 10 parts another metal or metals, making it 58.3% gold
10 karat (10K) gold contains 10 parts gold and 14 parts another metal or metals, making it 41.7% gold. 10k gold is the minimum karat designation that can still be called gold in the US.
Karat vs. Carat
The term carat, spelled with a "c," is often confused with the term karat. They are both pronounced the same, but carat refers to the weight of a gemstone. You could have a 1.5-carat diamond set in an 18 karat gold setting.
The karat system is used to 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 "solid gold jewelry" is a misnomer because, most times, this jewelry is not made up of solid gold. This term references jewelry that has a gold alloy throughout the entire piece.
On the other hand, the phrase "pure gold jewelry" is used to describe jewelry that is made up entirely of gold with little to no alloys present.
How a Gold Alloy is Formed
A portion of the gold is mixed with different alloys or metals, which creates a specific formula. Each gold color, like white gold or rose gold, uses a different combination of alloys.
Karat Used in Costume Jewelry
The term karat is also used on gold filled and gold plated jewelry. Even though these pieces are not solid gold, the gold portion of the jewelry has a certain percentage of pure gold designated through karats.
Expert Tip: If your piece of jewelry is marked 14KGF or 10KGF, that is a common indication that the item is gold filled and is not solid gold. However, the marking 14KP or 14KP does not necessarily mean gold plated. It also can stand for 14K gold plumb, which is solid gold.
If your piece of jewelry has a P in the marking, be sure to have the gold tested.
These values are primarily used on gold from the United States. You will see a lot of 22k gold and 9k gold in other countries. Gold jewelry from other countries may have an entirely different set of gold marking.
