To place an order simply send me an email with the following information:

  • Your name, address, contact info (email, phone, cell phone, etc.)
  • Your shipping address
  • Payment method (see below)

Once I receive your order I will reserve your piece(s) and then respond ASAP with a confirmation and the total.

California residents are required to pay sales tax of 8.25%. Orders to residents outside of California are not taxable.

I will ship your order immediately once I receive payment and funds are verified.

It is our policy to confirm all e-mails within 24 hours, and to notify you by e-mail when checks are received and when a package has been sent.

Shipping & Insurance

How much will shipping charges be?

We ship primarily via the United States Postal Service and all domestic orders are shipped by Priority Mail. It is the cheapest and the fastest, (usually 2-3 days).

Shipping charges may vary per order and are based on weight and destination.

Priority shipping is $3.85 for the first pound and then $3.95 - $5.75 for up to two pounds.

Heavier items will be charged according to United States Postal Service rates.

For international orders I ship via the United States Postal Service Global Priority Mail. The maximum weight limit is four pounds.

For international orders exceeding four pounds or to countries not serviced we can opt to ship via the United States Postal Service Global Express Mail or through other carriers, though additional charges will incur.


Insurance is optional for orders under $25.
For orders over $25 domestic insurance is $1.10 up to the first $50,
for$50.01 to $100 it is $2.00,
and for $100.01 to $5,000 it is $2.00 plus $1.00 per every $100 of value.

To check insurance rates please go to: USPS

International orders are not always insurable, however I am always willing to look into insurance on a case by case basis.


I want to take the uncertainty out of shopping on the Internet by providing a risk-free return policy. If you are not satisfied with something you have ordered, for whatever reason, please feel free to return it. Items returned in the same condition and within ten days of receipt will be cheerfully refunded or can be applied as credit towards another purchase. Simply notify me as soon as possible if you are planning on returning an item and I will refund your money when I receive it back. Please use the same care in packaging returns as was used in getting items to you. If you need more time to return items from outside the U.S. please arrange it with me. Otherwise, all sales are final after 20 days please.


Your privacy is a concern to me and all information is regarded as highly confidential.

In Conclusion...

Please remember, your satisfaction is of the utmost importance. If you have any concerns please let me know and I will do whatever it takes to address or resolve them. Also, if you have any questions, comments, suggestions, or just want to talk about minerals feel free to get in touch with me!
