Opal is the birthstone for the month of October, and the zodia sign Libra. The most popular types of opal are white opal and the fire opal. The fire opal (shown on ring RG227 above), is one of the rare highly transparent types of opal. The gemstone ranges in color from a pale orange to a more thickish reddish-orange tone. Both white opals and fire opals (infact all opals) have a natural moisture content as part of their composition. The moisture is responsible for the beauty of the gemstone. If you wish to make a wedding ring with the October birth stone, white opal or fire opal would be a great choice.
The RG227 has also been shown here for another reason, the ring is a 375 year old antique design and signifies love, friendship and loyalty. First made by an Irish slave named Robert Joyce, the ring is today internationally proclaimed as the most meaningful jewel in history. The design with the opal birthstone adds more meaning and significance to your birth stone wedding ring. When wearing, storing or cleaning your opal wedding ring, remember to keep it away from strong heat sources and chemicals. These are known to disturb the moisture content of the opal and ruin it's natural beauty. If you are considering a claddagh wedding ring with opal gemstone, check this link.
