This opal is believed to be app 14 -15 million years old.The opal has a tendancy to craze when dried too fast as it contains up to 14 % water. We just know we lose most to drying  but a small percentage is stable. Some cutters store the opal in mineral oil for a year and change it every 3 months before cutting.

As with all our stock we offer a full refund provided it is not touched in any way.
