I have a large turquoise thunderbird pendant (3 1/2’ long, 3 1/4" wide). The turquoise is light blue with a lot of brown veining. It has the following hallmark: D SECATERO. I have learned that this hallmark is an early one for Dorothy Secatero (per her son Randy). Photos are attached. It weighs approximately 100 grams (3.5 oz) and was purchased in Albuquerque sometime in the early 80’s.
However, I have been unable to determine a value–I have only been able to find a couple of listings on the internet and none were close in size or similarity to the pendant I own. Is anyone familiar with her work or could estimate the approximate value?
