Chemical composition Heat, humidity, sweat, and contact with water can cause the amount of water in opals to fluctuate. When this happens or when your opal pendant loses or gains water, its color changes. The amount of water in opals will fluctuate over time depending on factors such as humidity, heat, sweat, and contact with water. When an opal gains or loses water, its color changes.
This is not necessarily a bad thing, and sometimes this subtle change of color can make the opal look even more beautiful (and it certainly lends itself to the mystique of the stone). But you should be careful not to change the water composition of your opal too much. Some opals have internal structures consisting of silica spheres. These orbs are capable of diffracting light.
This diffraction separates light into its component colors, similar to a prism. This is known as “play of colors” and is what makes opal as desirable as a gemstone. Opal without this diffraction ability is known as “common opal”. I've also heard they call it “potch.” When white light waves enter the top of an opal, they refract and bounce off the inside of the opal, through all the microscopic spheres and the gaps between the spheres.
As light passes through spheres and voids, it diffracts (splits). Like a prism, opal divides white light into all colors of the spectrum, and light eventually bounces off the top of the stone, at which point we get a view of beautiful opal colors. Opal is the only known gemstone that is able to diffract light naturally in this way. The strange flashes of color of your opal and its ethereal glow make it look like pure magic.
However, they are known for their rapid discoloration. They often develop an unsightly yellow or even lose all color, and it is not uncommon. On the Moh hardness scale, which rates the ability of gemstones to resist scratching from 1 to 10, opals score from 5.5 to 6.5, placing them below amethyst at 7, but above pearls in the 3.5 range. When the spheres inside the opal are larger (about 3500 angstroms in diameter), the colors red or orange are produced.
For this reason, the presence of red in an opal can add a lot of value to its value, since it is something rare. Small spheres produce only blue opal (the most common), while larger spheres produce red (the rarest color). You shouldn't put an opal on an ultrasound, but you can shoot it with a photo of water to clean it. The spheres of an opal are not only remarkably uniform in size, but they are packed, in gem-quality opal, in a very regular set.
Sometimes called Welo opals, these opals have translucent to transparent body colors with a play of vivid colors in a variety of patterns. The Simple Shine Gentle Jewelry Cleaning Kit is specially designed to be used with softer stones such as pearls and opals. The buildup of dirt or grime, especially on the back of the neck, can make opals look hazy or dirty. Remove the opal ring when washing your hands, cleaning dishes, showering, relaxing in hot tubs, or swimming.
To conclude, an opal stone and another gemstone of the same stone size will not always have the same weight due to their respective specific weights. Opal triplets are usually made with an obsidian backing with a thin layer of opal and finally a thin layer of quartz or synthetic corundum is added on top.
