The “Burn Anne”, as it is locally known, rises in the hills a few miles to the south-east of the north Ayrshire town of Galston. This locality has long been famous for it beautiful jasp-agates.
The agate found here is mainly vein agate but very occasionally nodular fortification agates can be found in the burn. This beautiful vein agate is found as brick-sized blocks of material within the soft, almost clay like, pale green “rotted” lava. Occasionally can be found specimens that show a brecciated structure that has been re-cemented with the mineral Calcite.
The Burn Anne vein agate was described by Heddle as being “altogether unrivalled in beauty”. The colour of the agates includes red, orange, yellow and white and is associated with grey and pale purple chalcedony. Some of the most desirable material shows a white and yellow banding, this is classic from this locality.
Finding any agates from this burn is not easy and requires a lot of hard work. Only a few “dedicated” collectors have, in recent years, been lucky enough to find any worthwhile material from this locality. In the past the burn was the site of extensive workings but nowadays there is no evidence of these old "quarries".
