Ordering and Shipping

All jewelry is handmade and will ship within 1-5 business days. We will contact you if there is an unforeseen delay.
We offer ground, two-day or overnight shipping via UPS.
If you are interested in international shipping please email info@circadianstudios.com prior to placing your order.

Returns and Exchanges

Returns and exchanges can be made within 15 days of receipt of all unworn jewelry and will be credited in full.  We do not pay for return shipping.


We use 14K gold fill and sterling silver metal and chains, and the occasional brass component.
Gold fill is 14K gold electromagnetically bonded to a brass core and will not wear off over time, thus allowing the everyday woman to enjoy beauty and luster of 14K gold without today's high cost.


Each piece is lovingly handmade to order in San Francisco by skilled artisans.

Jewelry Care

Keeping your jewelry in zip-loc type bags is the best way to keep them from tarnishing due to air and moisture exposure.
Once tarnished washing in dish soap or using jewelry cloths are helpful (not on oxidized (blackened) silver pieces or the oxidation will be removed).  
Or an eco- friendly way to sparkle up your jewelry and remove tarnish:

     - place a piece of aluminum foil in a glass or ceramic bowl
     - place jewelry on top and liberally sprinkle baking soda on top
     - pour boiling water over and repeat if necessary to remove all tarnish
     - rinse with warm water and dish soap after to really shine

Do not place oxidized pieces in this solution or the oxidation will be removed.
