Beautiful gem stones with a fragile nature and possessing a riot of internal color, opals come from various locations around the world, but mostly from Australia. Most often recognized as a milky stone with an oil-slick of iridescent colors contained within them, they can also come in dark colors, such as in the black opal. Opals consist of silica gel and contain a high water content, which makes them potentially brittle and fragile if you let them dry out.
Miner take sheets of delicate opal with the mother rock beneath them, and usually process them into opal doublets. They are used for commercial jewelry where costs are kept lower since it is not purely opal. The thin layer of opal mounts on a stone of lesser value, or even on glass, then the manufacturer covers it with another substance like plastic, lead glass or hard glass to protect the opal layer.
Most recognizable as the flower used in making Hawaiian leis, plumeria is a tropical tree that grows in Hawaii, Mexico, South America and the Indies. The flower sports five well-defined petals and comes in many colors from reds and pinks to whites and yellows. Some of the flowers are variegated, with a stripe of pink down one side of each yellow or white petal. The tree grows to be about 18 feet tall, and blooms for the entirety of the spring and summer.
The soft vibrant colors of most opal is ideal for accenting jewelry that is crafted into the shape of plumeria flower. It pairs well with most precious metals, such as gold, silver or platinum. You should store opal plumeria jewelry with humidity to keep the stone from becoming too dry and breaking.
