More Information

Geode Gallery LLC is among the leaders in providing geodes for schools, universities, museums, boy/girl scout groups, and other groups that focus on activities with children.  We offer three types of small "break your own" geodes from Chihuahua & Sonora provinces in Mexico (Trancas, Coconut, and Sonora geodes).  Please review some of the most commonly asked questions we receive below.  If you have any additional questions, please use our Contact Us form at the top of this page.  Thank you for visiting!  Many of our "break your own geodes" larger than 1" in diameter are guaranteed at least 90% hollow - we do not sell solids!  Buy with confidence from Geode Gallery LLC!

What is the Difference Between the Mexican Coconut, Trancas, and Sonora Geodes?  The Trancas geodes contain mainly a clear or very light smoky quartz interior, wormy quartz growths and scepters, and most fluoresce a bright green under shortwave ultraviolet light.  The coconut geodes contain a variety of colors, including brown, smoky, light blue, clear, and 5% contain amethyst (purple) crystals.  Some of the coconut geodes also contain calcite, goethite, and other minerals as well.  The Sonora geodes all contain a clear quartz lining with occasional quartz scepters/growths and light tan calcite crusts, and many of these geodes flouresce a bright green color under shortwave UV light.  The Sonora geodes open up easier than their coconut and Trancas geode counterparts.

Which geode type and size do you recommend?  The answer to this question depends primarily on your budget.  You will encounter the same interior in each geode type regardless of the size of the geode.  It does not matter if the geode is smaller or larger, the interior is consistent throughout all sizes.  The coconut geodes are more popular given their colorful interiors even though they are more expensive.  If you have a UV light with shortwave power, the Sonora or Trancas geodes may be for you.  The Sonora and Trancas geodes are more budget-friendly.  We currently have one size of the coconut geodes in regular supply, and occasionally a slightly smaller size but these are in short supply due to low production of the small sizes being released from the mine.  Multiple sizes of the Sonora & Trancas geodes are regularly available.

How Quickly do you Ship?  Most orders ship same or next business day, and we use Priority Mail Flat Rate boxes whenever possible (2-3 day delivery in the United States).  Larger quantity orders (over 120 geodes) may ship more economically by Fedex Ground/Home Delivery (1-5 day delivery in the continental United States).  The shipping rate listed in our secure online shopping cart is the correct rate for orders under $100, and all orders $100 or higher receive free shipping in the USA!  Our shipping rates are listed below for orders under $100.  We reserve the right to ship by whichever method if "Standard Shipping" is selected, but if you do have a shipping preference, please include in the "Special Instructions" section of our order form.  Overnight and 2-Day Fedex options are also available for an additional cost.

Do You Offer Quantity Discounts?  We are sorry, but we do not offer quantity discounts.  Hollow geodes in these smaller sizes are in very high demand (noted by some sizes/types not always available) and we take extra time to make sure that what we offer for sale is indeed hollow.  We feel our prices are comparatively more than fair given our attention to making sure you receive at least the guaranteed percentage of hollows quoted and the quality of the hollow geodes.
