Due to its production of precious stones, many of them from the mines of Gerais, Brazil is a good country to buy jewelry. Some of the locations where it is easiest to find them are in Porto Alegre and Rio Grande do Sul, where there is an abundance of quartz, mandarin citrine, and lunar blue quartz. In Salvador de Bahia the most coveted is the emerald, with its characteristic green color. Finally, in the Amazon, the most common is beryl. Almost all of them can be bought in many of the jewellery shops that are located in large cities such as Rio de Janeiro, São Paulo or Salvador de Bahia, among others. One of the most prestigious is H. Stern, who designs for many Hollywood stars.
