Artist: Momoko Mary Koyama Halstead


Momoko Mary Koyama Halstead is the artist, designer, and owner of SPN.dylus670, a modernized cultural jewelry collection using spondylus shells. She is the first cultural producer from the Northern Mariana Islands to be featured in the Guampedia online gift shop. Halstead was born and raised on Saipan in the Northern Mariana Islands. She is a mother of three beautiful daughters who serve as her main motivations in life. Halstead’s passion for the arts and culture are ever-present in her work as she creates designs suitable for all ages so that one may, “take a piece of home wherever you may go.”

Halstead lives by the phrase “everything happens for a reason.” In high school, she was encouraged to join the Tasi and Ali’i’s Polynesian dance group by one of their musicians, the late Faaea “Uncle Tala” Talalemotu. Although hesitant at first, the words of Uncle Tala to “just try it out and if you don’t like it, just quit,” persuaded her to join. Halstead fell in love with the art form and has continued this love of dance for over 15 years, eventually becoming a team leader herself within the group

Halstead would enroll herself in the Northern Marianas College, taking classes by day and working as a cultural dancer for dinner shows by night. She obtained an Associate of Arts Degree with an emphasis in Education, becoming a special education teacher-aide at Kagman High School in Saipan, working to make a positive impact on her students through the education of school curriculum and life skills.

Despite an already busy schedule as a teacher, dancer, and mother of three, Halstead began a new hobby in jewelry making after spontaneously purchasing a used Dremel, a power tool used for grinding; sanding; and polishing, at a garage sale. Halstead started small by making pieces from spondylus shells to give as gifts to friends and family. In no time, the demand for her jewelry increased and she opened her business, SPN.dylus670, earning her respect as both an entrepreneur and artist.

Halstead keeps with her love of art and culture through her continued practices in dance and jewelry making. She continues to share her love of art through each piece of jewelry she makes and no longer has any hesitation to start something new, knowing she can “just quit” and move on to the next adventure.
