Bisbee Minerals - Gemologist Certified Specimens - Arizona USA Seller!Fine minerals and mining artifacts from Bisbee and around the world. Trusted Arizona Gemologist seller for over 40 years!Please mark us as a favorite seller to receive instant listing notifications!About this item(s): Extremely rare, very large Bisbee mining region "birds nest" calcite formation. One of the most sought after Bisbee specimens by worldwide mineral collectors. According to the estate information, this specimen is from the Southwest Mine Extension - long closed. The majority of Bisbee bird nest formations are in museums or tightly held in private collections. This must be considered if you want to buy, as this may be your only chance in a lifetime.Includes original stones (eggs) and mineral debris as found. Birds nests are formed over thousands or even millions of years as water drips on the mineral surface creating a bowl. Overtime, small pebbles are entrapped in the bowl and polished into egg-shaped minerals. One can only image the process and just how rare it is. The vast majority of Bisbee birds nests are broken and sold as repaired specimens. In addition, many of the original eggs are missing. Very, very few are found intact with the eggs and debris in the bowl.For shipping: All the original debris and eggs will be removed and placed in a secured plastic bag. This item is fragile. The back of this specimen was coated with a very thin coat of mineral sealer. Without this protection, it's doubtful the rare specimen would hold together. This item can also be picked up in Tucson.Size: About 4.50" x 3.50" height varying as seen.Weight: About 270g.Gemologist / Geologist Notes: Extraordinary specimen. These are no longer available as the Bisbee underground mines are long closed. Truly a priceless specimen.
Terms:Returns:
Please contact us for returns. We want everyone to be happy! Altered items (cut, damaged, drilled, polished, etc.), are not available for return, exchange or refund. Items damaged in transit can be returned. See shipping and return notes below.Theft:
Seller, host and the USPS do not cover "porch pirating," or other forms of theft. Track your packages and arrange for a secure delivery and receipt. Postal insurance does not cover theft once delivered.Combined Shipping:
We will combine all orders placed at the same time and refund any extra postage.Sizing:
Note measurement estimates in pictures, video and exact measurements in description. Some specimens may be larger or smaller than anticipated.Condition Notes:
As seen in pictures. Most specimens are not professionally cleaned so dirt may be present. Some specimens may be stabilized without our knowledge, as some processes are very hard to detect. Some specimens may have odors from long-term storage or natural sources. Old mounting glue, residue, tags or mouthing material may be present. Some specimens may not sit upright as seen in pictures and may require a stand or other propping device. Saw marks may be present on any rough, cabochons, slabs or specimens. Some cabochons may appear smooth in pictures but may have small vugs, natural fractures, edge chipping or other imperfections.Pre-Shipping Breakage: Because minerals are often unstable, some with micro cracks or other unforeseen imperfections, we may not be able to fill an order if the specimen is discovered as broken or unsteady upon second examination. In such situations, the buyer understands and agrees to hold the seller harmless (including response). All non-shipments will be immediately refunded.Slab and Lapidary Warranty:
Al slabs or lapidary rough can have unforeseen weaknesses including hidden cracks and soft / weak areas. There is no way to test slabs without attempting to break them with applied pressure. We strongly suggest stabilizing or backing any slabs that could potentially break during any lapidary work. There are no refunds in the event of breakage due to handing or lapidary work after you receive the slab. The buyer accepts there are risks in lapidary and gemstone work regarding the interior matrix, and such matrix may not yield desired results. Therefore, there are no refunds for lapidary rough based on inferior or unexpected interior content.Specimen and Lapidary Hazards:
Many rocks and minerals (specimens) contain potentially hazardous or allergenic compounds, some known or unknown. Some specimens (as noted) may be coated with polyurethane to provide a wet look. Always wash hands after handling raw specimens. Specimens should never be applied to skin or ingested. Lapidary work should always be preformed with safety equipment including inhalation and skin contact considerations. Specimens should not be used in aquariums or terrariums without establishing safety first. Do not allow children to handle specimens. Buyer assumes all responsibility for the safe handling of specimens.Images:
All specimens are photographed with bright, natural sunlight or artificial daylight at 5000K to 5500K to show accurate colors and details. Specimens viewed in poor / indoor lighting or non-daylight illumination sources may not appear as in the photographs. Some specimens (as noted in the description) may be seen wet or damp to show lapidary potential. In such instances, received item(s) may appear duller until professionally polished. Items used for backgrounds, props and measurements such as rulers, coins, etc., are not included unless otherwise noted in the description.Warranty:
We do our best to accurately describe our mineral specimens or rough. However, as it is with most minerals, it's impossible to determine the exact interior structure or content, so we cannot warranty or refund specimens or rough used for lapidary work or excessive handling. Some items may break or chip during transit due to unknown micro-cracks. These items may be returned for a refund.Porch Pirating and Non-Delivery Addresses:
USPS insurance only covers delivery to your address. Insurance does not cover packages after delivery, including packages stolen from doorsteps, mailboxes or mail holding, such as apartments offices or private mail holding facilities.
