Boulder opal is one of the most valuable varieties of opal, second only to Australia's black opal. Fine specimens of boulder opal can exhibit all of the spectral colors through their distinct play of color. Boulder opal may be considered to be less valuable than black opal, but it is actually much rarer and harder to find. Opal contains every color of the spectrum, from deepest and clearest blues and iridescent greens, through to golden orange, red and fuchsia; it can be pale and delicate, or dark and brilliant. Due to its structure, opal may contain any combination of an infinite number of patterns and may reveal itself all at once - glorious from all directions – or it may be quiet and surprising, showing its greatest brilliance only during flashes of movement. Indeed, precious opal is like no other gemstone because it changes color as the observer turns the stone. Opal is an excellent journeying stone, highly receptive, inducing a mild hypnotic state for enhancing divination and metaphysical gifts.

Care instructions
We recommend using caution when cleaning your natural earth mined, untreated gemstone jewelry. We do not recommend using ultra-sonic machines or chemical cleaners which could alter the color and clarity of the gemstone.
Most stones respond well to mild detergent and warm water. Scrub them using a soft brush, preferably a baby brush with soft bristles. Avoid scrubbing too hard else you may end up scratching the stone. Rinse the stone and dry it gently with the help of a soft, lint-free cloth.
