Tucson on $50K a day: open your wallet. The Tucson gem and mineral shows aren't just for buying $25 bags of blue topaz and smoky quartz.(Buyers guide)

No matter which Tucson show you attend, whether it's the premier AGTA GemFair at the convention center or one of the I-10 tent shows, you'll see plenty of top-quality goods for those with deep pockets.

The high end includes more than the big four--diamond, emerald, ruby, and sapphire. Other gem material with very fine and unenhanced clarity, untreated color, fine cutting, and large sizes also qualify. Look for rare gems, like large specimens of fine Lightning Ridge black opals, Kashmir sapphires, and strands of large South Sea pearls.

Here are some of the gems and jewels that made our list of what we'd buy with $50,000 or more per day. If only.
