Ordering Information

Acceptance Mark

To order a mineral, please contact me to enquire about the specimens availability. You can either send me an e-mail at mike@marinmineral.com with the mineral number and a description of the mineral or give me a call at 415-342-1852. I will then confirm the specimen's availability status and follow-up with regard to shipping preferences and payment methods. Minerals will be sold on a first come first served basis. Please remember to look at the measurements of the minerals before ordering as some thumbnail sized specimens are shown larger than actual size and some large specimens are pictured smaller than actual size. If you are a California resident, a sales tax of 9% will be added to your order. Shipping charges will be $8.00 to $15.00 for most domestic orders. Small shipments out of the USA can be shipped for $10.00 with no insurance or via registered airmail for $25.00. Larger shipments out of the USA typically cost about $50 for insured shipping. Expedited shipping out of the USA can also be done using FEDEX for approximately $75-$125.
