Factors to Consider When Buying
Opal comes in a variety of sizes and colors, so choosing one can be a difficult decision to make. Here are a few things to consider when buying an opal engagement ring for your loved one.

Color
One of the most important factors to consider when making a purchase is the color. It tells you a lot about the opal’s value. The more colors visible, the more valuable it is. Colors such as orange, red, and pink are rare. Therefore, the more an opal depicts these colors, the more valuable it is.
Color Clarity
An opal’s clarity is measured in terms of the color’s tone, saturation, and hue. For instance, a bright blue tone is much more valuable than a greenish or light blue tint. Pure red is highly popular in an opal.
Fire Brightness
The opal’s fire or color play is measured on a 1 to 5 scale. Level 1 indicates a faint play of color and only when it is under direct sunlight. Level 2 is dull, which displays some color in low light but remains dull in indirect sunlight. Level 3 is bright and displays a good amount of color in low light while a nice visible fire in indirect sunlight. Level 4 is very bright with good colors in low light and crisp colors in indirect sunlight. The final level 5 is brilliant and displays crisp, bright colors under all types of lighting.
Coverage
The coverage means the surface dimensions which display the play of color. The less area covered, the less valuable the opal. In order to obtain maximum value, the play of colors needs to be in the center. Off-centered or side display of colors means the opal is less valuable.
Clarity or Imperfections
Inclusions in opal can include healed fractures, webbing, chips, sands, or sandstones present between the fractures and area of color. Opals are delicate and can, thus, get highly reduced in value due to fractures or sand visible through the layers. Opals that are cracked do not make good jewelry stones.
Cut
An ideal cut for an opal would be even proportions with a high dome. However, very few opals allow this shape. The polish of the opal should also be good for higher grades. The value of an opal decreases when it’s extremely thin or extremely thick. What further results in the value reduction of an opal is an uneven cut. As in the case of all cabochons, opals need to be symmetrical when they are viewed from the ends or sides. If the symmetry is uneven, the cut grade will be lower. However, symmetry has no effect on the opal carving’s value. In the case of carved stones, their overall carving is what affects their value.
Carat
Even though the size of the stone does have an effect on the value, large opals do not come at a higher price than the mid-sized ones. The higher value is for gems measuring between 5 and 10 carats.
Tips for Keeping Your Opal Ring Clean

- You can keep your solid opal ring shinier and clean by using a mild soap and soft cloth in warm water. This should easily clean the grime or dirt accumulated on it. Just add some mild soap into warm water and make a foamy solution. After that, you can submerge your ring in the water for just a few seconds and use a soft cloth or soft brush to work on the grooves and crevices. Once done, you can wipe it off using a lint-free cloth. Do not use this method on doublet or triplets as it can affect the glue, causing the parts to separate.
- The shine or luster of your opal ring can go dull with time. You can get the opal polished professionally to restore it back to its smoothness.
- To clean a doublet or triplet, simply use a mild detergent with a damp, soft cloth and wipe it clean. Keep in mind, though, not to immerse or soak your ring in the detergent or water as that can cause damage to it.
- Keep your opal ring in a padded cloth bag if you want to store it for a short period of time. However, for longer time periods, pour a few drops of water on cotton wool, keep your ring in it and then keep the cotton wool in a sealed plastic bag.
