This is one of Stella Chavarria's nicest Water Serpent bowls or pieces I've seen ,Large hand made & carved bowl  with a traditional water serpent circling the bowl ..
    It measures 6" in Diameter X 4" inches high . substantial beautiful flowing large piece of Museum quality pottery .
         Stella Chavarria is listed in the booklet " 7 families of Pueblo pottery Maxwell Museum UNM Press published in 1974 .  She is the daughter of Christina Naranjo whose  mother was
 Sarafina "Geronimo" Tafoya 
The matriarch of Santa Clara Pueblo pottery. 
  I estimate imho  the piece was crafted in 1970's or the early 80's making this 40 plus yrs ago imho..
  The bottom is signed by Stella has a old penned price of $160.00 . 
 I do know that 30 yrs ago a nice baseball sized carved blackware bowls , I saw visiting Potter's home's at Santa Clara Pueblo , in home of Santa Clara Potter's ,then asking price  approximately $190.00 -$250.00
 This bowl is double the size of those I saw at Santa Clara 30 years ago with my own eyes .
 Please feel free to ask any questions
   Thank You
