Seller's terms and conditions

Rockhunter does not sell by size or weight. Sizes and weights given are just for the basic orientation of the buyer and shipment planning and might not be exact, even though we're always trying to be as exact as possible.

Photos might show the item in an enlarged or reduced dimension. Please refer to the given sizes. Please note that all photos have been adjusted – e.g., trimmed to show a certain aspect/a detail, colours adjusted, contrasts highlighted etc. to give the customer an optimal impression, while we try to stay as close to the natural appearance as possible. If it shows that photos cannot depict the natural appearance correctly, we will usually mention this (e.g., all Dioptase photos will never show the rich colour and lustre of the mineral). However, the colours on other photos might be a little off too. Also, computer screens might show colours differently.

We assume that the buyer has a basic knowledge of minerals and, on the one hand, has informed himself about possible toxicity and is aware of dangers in handling them. On the other hand, he must also have informed himself about how certain minerals are to be handled and stored – e.g., about resistance to cleaning agents and solvents, sensitivity to light and the like. Rockhunter accepts no liability whatsoever for injuries, health consequences and incorrect treatment of any kind.

All texts and pictures are copyright by Rockhunter Handels UG. The buyer may use pictures and texts of the items he bought for personal use only. For commercial and academic uses you have to ask for permission.

We reserve the right to decline service to customers who have exhibited antisocial or unfair behaviour towards us or our colleagues, or people who are known to us as cheats or troublemakers. Upholding principles of fairness and decency is of utmost importance to us, and we will make every effort to prevent conflicts or, where necessary, swiftly find satisfactory solutions for both parties.
