Want a rock that knows how to keep a secret? This Mexican Green Opal saves its best trick for the dark.
 
In regular light, this rough, unpolished slice shows off an earthy mix of green and yellow-green with natural matrix and contrasting colors running through the stone. Its variations in color and texture give you plenty to look at before you even reach for the UV light.
 
And then things get interesting. Under ultraviolet light, areas of the opal light up with brilliant fluorescent green, revealing patterns and features that are barely noticeable in ordinary lighting. The difference can be dramatic, making this one of those specimens that's just as much fun to show off as it is to add to your own collection.
 
Green Opal carries a soothing energy traditionally connected with the Heart Chakra, emotional healing, and renewal. It's a wonderful stone for times of change, encouraging you to release what no longer serves you while making room for growth, compassion, and a fresh perspective. Its gentle energy is also connected with emotional balance, helping to bring a greater sense of peace and harmony when life feels a little unsettled.
 
Whether you're drawn to Green Opal for its energy, its natural beauty, or simply because you love a rock with an unexpected side, this piece gives you a little of everything. Keep it somewhere you can enjoy its earthy colors during the day—then wait until someone isn't expecting it and reach for the UV light. 
 
Please note: UV photos show this piece under ultraviolet light. Fluorescence and color may appear differently depending on the UV light source and surrounding lighting conditions.
