After emeralds, aquamarine is the best known beryl. It is a durable and lively gemstone that is appropriate for all jewellery pieces. Its pale fire is flattering to most skin tones. Aquamarines are found in Brazil, Zambia, Mozambique, Angola, Nigeria, among other countries. It is always a pastel blue, but the darker the colour, the more valued it is.
Connoisseurs also prefer a pure blue with no green in it.
If you prefer a greenish tinge, you will find that these stones are less expensive. The largest gemstone quantity of aquamarines ever mined was in 1910 from the Marambia, Minas Gerais, Brazil. It weighed 243 lbs. Since the colour is generally pale, aquamarine should have good clarity. More saturated colours are unusual in small sizes as it takes some size for the colour to hold in a darker shade.
