The ruby gemstone, known for its scarlet color, is the rarest gemstone. Very fine quality rubies, especially stones in larger carat weights such as over three carats, are very rare and incredibly valuable. Such rubies are rarer than high quality colorless diamonds. Rubies are mined in Myanmar, Kenya, Pakistan, Sri Lanka, Tanzania and Vietnam. Ruby is the birthstone for those born in July.
The emerald gemstone, known for its rich green color, is a gemstone that has been an emblem of rebirth and enduring love for thousands of years. No other green gemstone can rival the emerald’s beauty and popularity. Although when you think of emeralds you think of a rich green color, but emeralds can be found in a variety of hues and tones. Some of the finest emeralds are slightly bluish green in color. Emeralds are mined in Africa, Brazil, Colombia, Russia and Pakistan. Emerald is the birthstone for those born in May.
The sapphire gemstone, thought to only be blue in color, can be found in a variety of colors such as purple, pink, yellow, orange, green and gold. Sapphires have long been a symbol of truth, honesty and faithfulness. Sapphires are mined in Australia, India, Myanmar, Sri Lanka, Thailand and the United States. Sapphire is the birthstone for those born in September.
The last to make up the big four in gemstones is the diamond. Although when most people think of diamonds they usually picture a clear gemstone, diamonds have been found in red, blue, pink, green, and bright yellow colors. Diamonds are mined in Australia, Africa, Asia, and North America. Diamond is the birthstone for those born in April.
