Price of gold

The price of gold is determined by the London Buillion Market Association (LBMA). This trade association comprises more than 100 global banks, financial institutions and precious metals stakeholders. It sets standards for the value of gold and silver, good business practices, and standard documentation.

The valuation of a gold piece should always be done by certified experts, with proper instruments and based on the weight, antiquity and carats of the piece.

Buy gold bars

Do you want to buy gold bars? Gold is a metal that does not oxidize. Therefore, gold bars do not lose their characteristic. However, the gold stock exchange price changes daily, so the value of the gold bars is not the same at the time of buying and selling.

There are various weights: 12.5 kg, 1000 g, 500 g, 100 g, 50 g, 31.1 g, 20 g, 10 g, 2.5 g, 2 g, and 1 g.It is recommended to divide the amount invested into several bars of different weights rather than just one bar of greater weight. This is because at the time of selling, it is easier to sell.

Gold bars from 1g to 1Kg.

Ouro Avalia evaluates, buys and sells gold bars for investment, with international certificate and VAT free.
