[QUOTE="blisters, post: 306038, member: 4992"] It is pretty but given the size and the relative lack of colour per sample size I wouldn't expend too much effort if any if you were looking to sell it, there is heaps of opal on dark matrix around which give a far better result. But as a specimen one solution I heard of is to soak the specimen in multiple dips of very diluted mix of water and aquadhere which then sticks loose material together but also seals and coats the rock which might be a useful trick if you slice and flatten on a wheel first. This technique is used to stick and coat fragile crystal specimens together as told by a seller of crystals but I have never tried it. Jon [/QUOTE]
