NOTES ON ULTRAVIOLET: The higher quality the Ultraviolet (UV) source, the better fluorescent minerals look. Critical factors include; filtration (Hoya glass vs Plastic filter or lens), lamp wattage, bulb composition, lamp construction, wave length and distance of lamp to specimen. For best results with any UV source, observe against a black, non-fluorescent, non-reflective background, in complete darkness with eyes adapted. To dark adapt your eye's, you must be in complete darkness for approximately seven (7) minutes. The photos here were taken using a Shortwave (SW), Midwave (MW) or Longwave (LW) lamps, metered and exposed to show fluorescent response to its best advantage . The more powerful the ultraviolet lamp, the brighter the fluorescent response. I will indicate which wavelength is appropriate for the particular specimen being offered at auction and wavelength (SW/MW,LW) used as well as the wattage of UV lamp used for photography. I use 2-9 watt lamps to illuminate most specimens. With some specimens I use a Super Bright II and a single 9 watt overhead lamp for proper illumination. Weight and measurements of rocks are approximate and do not account for necessary shipping materials (box, bubble wrap, labels, tape, etc) which can add anywhere between 4 ounces (minimum) to 10 ounces per parcel. PLEASE READ Please pay within four (4) days unless other arrangements have been made. Due to recent changes at Ebay, it is now necessary for me to ship purchases within one business day of receiving payment. I will often ship the same day if payment is made sufficiently early. Please, if you want to combine shipping with subsequent purchases, do not pay until I invoice you with the correct discounted combined shipping. Just let me know when you are ready for the invoice. If you pay, I have no choice but to ship. I will hold an "open box" for up to 14 days allowing you the opportunity to add items to one box and thereby minimizing shipping charges. International shipping is not cheap and PayPal adds to the problem by charging a higher percentage for international transactions. Ebay also charges a commission on the shipping paid for both international and domestic purchases. I charge you what it costs me - I do not profit from shipping. Once I mail or ship a package, the time in route or ANY damage to specimen(s) is out of my control. I do pack all specimens using the latest techniques and care. If you are not happy with an item, please contact me first before leaving feedback or opening a case. I will take care of you and make it right.
