Handbook of Gemmology

Frequently Asked Questions

1. I downloaded the files but I can’t seem to get them to work properly?

It is important to either download the files onto your computer or copy the files from the DVD before you try to sync them to your other devices. Although there are four file formats on the ‘Deluxe’ edition download or DVD, only two of them are designed for your computer; the .exe (Windows) and the .app (Mac). You can of course view the encrypted pdf on your computer but this has been specifically designed to be used on iPhones, iPads, androids and most other e-readers with the exception of Amazon's Kindle. It is also important that your computer satisfies the minimum system requirements (please click here for more information). This not only includes the required operating systems but also space requirements and having sufficient memory. The ePub and PDF formats will allow you to view the book on your iPhone or iPad but must be synced first through i-tunes (see product information).

2. Whenever I try to open the handbook on my Mac, it says 'blocked plug in'. What does this mean?

It means that you have not updated your Adobe Flash Player. Go to system preferences, click on flash player and make sure that the option 'Allow Abode to install updates' is checked.

3. I downloaded the file onto my Mac but I get the prompt 'Handbook of Gemmology 2015 Edition V200600 can't be opened because it is from an unidentified developer'?

If you're running OS X Mountain Lion on your Mac there's a feature called 'Gatekeeper'. The primary function of Gatekeeper is to prevent malware like viruses and trojan horses from accessing your Mac. Gatekeeper does this, by default, by only allowing apps that are downloaded from the Mac App Store or from "identified and trusted developers" be opened. There are a few ways to bypass Gatekeeper if you run into this issue. Please click on the following link:

4. I tried to open the 'Mac' version but it says the file is corrupted?

The Mac file arrives on your hard drive as a .zip file which is a compressed file type that protects it during its journey through the world wide web. If your web browser is Safari (as it is for most Mac users) you will need to rescue the .zip file from your Trash. If you are using a browser other than Safari you can skip down to the fourth paragraph in this FAQ section.

Safari downloads the .zip file, automatically derives an uncompressed version which it then places into your downloads folder, and throws the original .zip file into the Trash. The uncompressed file in your Downloads folder will be corrupted and unusable! You must eventually throw it into the Trash, but wait to do that until later.

You must open your Trash folder where you will find the originally downloaded zip file. To open the Trash folder simply roll over and click your Trash icon in the Dock. Now find the downloaded .zip file, drag it out of the Trash window and put it into the location you wish to eventually store The Handbook of Gemmology. If you don’t know yet where that will be you can simply drag it onto your Desktop.

Once on your hard drive, the .zip file needs to be expanded before you can read it. The Mac OS has built-in software that will expand many kinds of compressed files including .zip. Unfortunately, our .zip file becomes corrupted when uncompressed by this built-in Mac OS software. The solution is to download a free utility called Stuffit Expander which is available through:

http://www.stuffit.com/mac-expander.html

Once Stuffit Expander is installed on your Mac, open the Finder window that contains the downloaded .zip file (which you have retrieved from the Trash if you are a Safari user). The trick now is to hold down the Control key while you click and hold on the .zip file. This drops down a contextual menu. In that menu you will find the sub-menu named ‘Open With’. There you will find Stuffit Expander. When it is selected the .zip file will be safely uncompressed.

The first time you launch the book file you may need to open it by again holding down the Control key to drop down the contextual menu from which you will select Open. Thereafter the book will launch normally.

5. Where can I buy the book?

Right here...right now. Simply go to our on-line shop, select the format you would like to buy and then proceed to the check-out.

6. What is 'Flipping Book' technology?

It's the latest technology for reading books on your computer. We offer it in both .exe (Windows) and .app (Mac) versions and it does not require any additional software other than Adobe Flash Player, which is a free download available from Adobe. This technology gives you the sensation of reading a printed book but in a digitized format. Unlike a traditional book, flipping book gives you many added features such as a search engine, zoom capabilities, hyperlinked table of contents and index, bookmarks, post-it's, highlighting and hyperlinked cross references. We also believe it adds an element of fun to reading that you cannot get with a traditional book.

7. Who should buy this book?

Whether you have a casual interest in gemstones, wish to become a gemmologist, work in a jewellery store and would like to know more about the products you are selling or are a practicing gemmologist, this book is for you.

8. Why should I buy the 'Deluxe' edition download or data DVD?

Most people have more than one computer, an iPad, an iPhone and even an e-reader. The 'Deluxe' edition comes with all four-file formats for only $ 10.00 US more. This offers you far more versatility, flexibility and value.

9. Do you take credit cards?

Our e-commerce site is set up to take PayPal. Whether you are a member or simply a guest, PayPal offers you a variety of payment methods and the security of dealing with an established company. For payments with American Express please contact us directly for processing orders.

10. Do you offer refunds?

Unfortunately the book is sold in a digital format (either as a straight download or as a data DVD) so we cannot offer refunds.

11. What about future editions?

We want this book to be the most up-to-date gemmological book available. Every May, starting in 2014, a new edition will be released with updated information, photographs and eventually even videos. If you register your purchase with us, by simply sending us an e-mail telling us your name, place of purchase and date, we will add you to our 'Preferred Client' listing. This will ensure that you are notified the moment a new edition is available and that you receive a preferred price on the new book.

12. Do you offer the book on a data DVD?

Yes. This is available to individual users who prefer not to purchase the book as a digital download and to schools and resellers who require a physical product to sell.

13. What about shipping?

We charge a flat rate of $ 10.00 US for individual DVDs. All shipments originate from Spain. We also provide free shipping on any non-institutional orders in excess of $ 150.00 US.

14. Can I get expedited shipping?

Absolutely, instead of buying through the on-line shop, simply e-mail us at rsvp@handbookofgemmology.com. stating how many data DVDs you would like, where you want them shipped and your preferred choice of shipping. We will issue you a pro-forma invoice and instructions on how to pay for it through our website. Expedited shipments do not qualify for 'Free Shipping'.
