Sand and Spark specializes in permanent jewelry at 560 North Coast Highway 101 in Encinitas, micro-welding 14k gold-fill and solid gold chains directly onto the wrist, ankle, or neck without a clasp. The pulse-arc welding technique fuses chain ends in a fraction of a second, placing the service in the same commitment-driven category as custom ink at 454 Tattoo and Body Piercing on North Coast Highway 101. Clients choose from a chain library that includes cable, figaro, satellite, and box-link profiles in varying gauges, with optional charm attachments soldered on at the time of welding. The appointment-based studio format lends itself to group bookings for bridal parties, birthdays, and friendship-bracelet sessions, a social beauty experience that pairs naturally with the nail and lash appointments at Flora Blanc Nail & Lash Studio. Each weld point is finished flush to prevent snagging, and the solid-gold options carry the same lifetime oxidation resistance as conventionally clasped fine chains.
