95% of the world's opals are found in Australia.
The remaining 5% are mined in Idaho and Nevada in the United States; Mexico; northern Brazil; Ethiopia; and Mali.
Australia produces 97% of the worlds opals, so it is unlikely that there is any country to which Australia does not export. One may safely ignore the possibility of a trade boycott.
It depends. All gemstones other than pearls and opals are crystals, but most crystals are not gemstones.

Opal should sink as the minerals contained within are heavier than water.
Opals are worth more then amethyst because usually the amethyst are not genuine.
Opal is mined mainly in the country of Australia. It is also found in Nevada in the United States. You can also find opal at a Natural History Museum or a Rock Shop in your area, a good chance to study a variety in person. The Natural History Museum in Cleveland has an amazing collection. At a rock shop you can touch and feel the opal, so much better than browsing on the internet, which is a good source for information. One of the best rock shops is ROCK STAR CRYSTALS in Manhattan in NYC. They have a large variety of opals to look at, including fire opals, pink and blue andean opal, australian opals, ethiopian opals, honey opal, green opal, and even opal jewelry. Might be worth a visit to NYC just to check them out - and you can be awed by the mineral collection at the NYC Museum of Natural History at the same time!

The gemstone (rather than jewel) for which Coober Pedy is famous is opal.
Australia is rich in natural resources, which give the nation considerable wealth. Its mining sector, while periodically undergoing normal boom and bust times, is particularly strong, enabling the country to have a very strong economy. As a result of this, Australia trades with a great many other countries, as it can offer iron ore, uranium, opals, diamonds, nickel, tin, gold, silver and lead, just to name a few. During the recent worldwide Global Financial Crisis, Australia weathered the economic storm much better than most other countries.
