No. Amethyst has a vitreous (glassy) luster.
Yes, nickel has a luster. It is a silvery-white metal with a shiny appearance.
This depends on what you mean by "shine granite". If your granite counter top looks dull and you're looking to bring it back to its original luster, you might want to look into some Dia-Glo diamond polishing compound, a felt wheel, a velcro backer pad, and a variable speed grinder. This is normally what professionals would use to "shine granite" back to its original luster after years of wear and tear. This can be done by someone that is not a professional if he or she is handy and has a good idea of what to do. I would not recommend this to someone who does not have proper instruction. There are DVDs for Fabricating Granite for the Do-It-Yourself out on the internet that will explain exactly how to do this, what you need, and what this type of job would require. If you're looking to take raw granite that has never been polished at all and "shine granite" then you're looking at an entirely different process. This process is also well documented with DVDs on Fabricating Stone for the Do-It-Yourselfer. This process takes a variable speed grinder, a set of about 8 diamond polishing pads, and a lot of elbow grease. There are many types of polishing pads for granite and other natural stones, but the general use of these and process of polishing is the same. If you are doing this I would also suggest contacting a professional or getting How to Granite DVDs to instruct you on the basics of this. The previous answer given about ager isn't necessarily to shine granite. Ager will restore the granite's luster to a point, but it's normally used for color variation matching. Imagine a sidewalk before it rains. Now imagine the sidewalk after it rains. The Ager will make your stone look like the sidewalk after it rains. It simply brings out the color. Honestly, without proper instruction I would not go about doing this myself. Either get an instructional DVD and learn about the process or hire a professional. On the other hand, working with stone isn't something that takes years to learn. It's just like working with any other product - a little practice and the right tools and you're all set!
