Up to this point, you can correct your entries or withdraw from the contract declaration.

§ 3 Correction notice

  1. As part of the ordering process, you first place the desired goods in the shopping basket. There you can change the desired number of items at any time or remove selected goods completely.

Finally, an overview page opens where you can check your details. You can correct your input errors (e.g. regarding payment method and address data) by clicking on "Change" in the respective field. If you wish to cancel the ordering process completely, you can simply close your browser window. Otherwise, your declaration becomes binding after clicking the confirmation button "Order with obligation to pay".

§ 9 Delivery conditions / presentation of the goods
  1. 9.1

  2. Images of goods in advertisements, brochures, in the online shop and so on are for illustration purposes only and are not binding. The same applies to details of the individual goods, as these are for information purposes. Only the manufacturer's specifications are authoritative (e.g. regarding manufacturer's warranty). We reserve the right to change the goods specified in the online shop at any time and without prior notice and to limit the number of goods that can be purchased by a customer.

  3. 9.2.

  4. All information in the online shop on the availability and delivery time of goods is without guarantee.

  5. 9.3.

  6. If the Seller is unable to meet a delivery deadline for reasons for which it is not responsible (non-availability of the goods, for example due to force majeure), the Seller shall notify the customer of this without delay, stating the new expected delivery deadline, if applicable. If the new delivery period is not acceptable to the customer or if the goods are no longer available in part or at all within the new delivery period, both contracting parties shall be entitled to withdraw from the contract with regard to the goods concerned; in this case, the seller shall immediately reimburse the customer for any consideration already paid by the customer with regard to the unavailable goods.

  7. 9.4.

  8. Delivery shall be made subject to the condition of timely and proper self-delivery by the suppliers. In the event of force majeure such as strikes and other industrial action, riots, war, natural disasters as well as suspension of delivery by the manufacturer or sub-supplier, there shall be no delay in delivery. The seller is not liable for delays in delivery caused by manufacturing companies or third parties.

§ 10 Transport damage

  1. If goods are delivered with obvious transport damage, please complain about such faults immediately to the delivery agent and contact us as soon as possible. Failure to make a complaint or contact us has no consequences for your statutory warranty rights. However, they help us to be able to assert our own claims against the carrier or the transport insurance.

§ 11 Right of withdrawal

  1. In the event that you are a consumer within the meaning of Section 13 of the German Civil Code (BGB), i.e. you make the purchase for purposes that can predominantly be attributed neither to your commercial nor to your independent professional activity, you have a right of withdrawal in accordance with the following provisions. The conditions listed below apply exclusively to the products ordered in the Diagen Diamond online shop!

  2. 11.1.

  3. You have the right to withdraw from a contract concluded online within fourteen days without giving any reason. The withdrawal period is fourteen days from the day on which you or a third party named by you, who is not the carrier, have taken possession of the (last) goods. In order to exercise your right of withdrawal, you must send us

      1. Diagen Diamond GmbH
      2. Keupstraße 68
      3. 51063 Köln
      4. Germany

      5. Phone: 0(221) 27848560
      6. E-Mail:
  1. by means of a clear declaration (e.g. a letter sent by post, fax or e-mail) of your decision to revoke this contract. You can use the attached model withdrawal form for this purpose, which is, however, not mandatory. In order to comply with the withdrawal period, it is sufficient that you send the notification of the exercise of the right of withdrawal before the expiry of the withdrawal period.

  2. 11.2. Consequences of revocation

  3. If you withdraw from this contract, we must repay you all payments that we have received from you, including the delivery costs (with the exception of the additional costs resulting from the fact that you have chosen a type of delivery other than the cheapest standard delivery offered by us), without delay and at the latest within fourteen days from the day on which we received the notification of your withdrawal from this contract. For this repayment, we will use the same means of payment that you used for the original transaction, unless expressly agreed otherwise with you; in no case will you be charged for this repayment. We may refuse repayment until we have received the goods back or until you have provided proof that you have returned the goods, whichever is the earlier. You must return or hand over the goods to us or to one of our branches without delay and in any case no later than fourteen days from the day on which you notify us of the cancellation of this contract. The deadline is met if you send the goods before the end of the period of fourteen days.

  4. 11.3.

  5. You only have to pay for any loss in value of the goods if this loss in value is due to handling of the goods that is not necessary for checking the condition, properties and functioning of the goods. Please avoid damage and contamination. If possible, please return the goods to us in the original packaging with all accessories and with all packaging components. If necessary, use protective outer packaging. If you no longer have the original packaging, please provide adequate protection against transport damage with suitable packaging in order to avoid claims for damages due to defective packaging.

§ 12 Warranty for purchases of goods
  1. 12.1.

  2. Unless expressly agreed otherwise, your warranty claims shall be governed by the statutory provisions of the law on sales (§§ 433 ff. BGB).

  3. 12.2.

  4. If you are a consumer within the meaning of § 13 BGB (German Civil Code), the limitation period for warranty claims for used goods is - in deviation from the statutory provisions - one year. This limitation does not apply to claims based on damages resulting from injury to life, limb or health or from the breach of an essential contractual obligation, the fulfilment of which makes the proper performance of the contract possible in the first place and on the observance of which the contractual partner may regularly rely (cardinal obligation) as well as to claims based on other damages which are based on an intentional or grossly negligent breach of duty by the user or his vicarious agents. The product illustrations may differ from the appearance of the delivered products.

  5. 12.3.

  6. If the goods are defective, we shall provide subsequent performance within a reasonable period of time, i.e. either replacement delivery or rectification of the defects. The place of performance for subsequent performance is our registered office. If the supplementary performance chosen by you is only possible at disproportionate expense, we shall be entitled to provide supplementary performance in the other form. The expenses required for the subsequent performance shall be borne by us. If a reasonable period of time for subsequent performance has elapsed without result, you shall have the right, at your option, to rescind the purchase contract or reduce the purchase price. If you decide to cancel the purchase contract, the services received by both parties must be returned and any benefits derived must be surrendered. If you are unable to return the goods received in whole or in part or only in a deteriorated condition, you may have to compensate us for the loss in value. However, the deterioration caused by the intended use shall not be taken into account. Claims for defects become statute-barred 2 years after the date of delivery of the goods.

  7. 12.4.

  8. The consumer's statutory rights under the warranty/liability for defects apply. Possible additional guarantees provided by the manufacturer improve the legal rights. In the event of a warranty claim, you can contact the manufacturer directly or the company Diagen Diamond with its entire branch network. In all other respects, the statutory provisions apply to the warranty.

§ 13 Limitations of liability

  1. We shall be liable without limitation for intent and gross negligence as well as in accordance with the Product Liability Act. We shall be liable for slight negligence in the event of damage resulting from injury to life, body and health of persons. In all other respects, the following limited liability shall apply: In the event of slight negligence, we shall only be liable in the event of a breach of a material contractual obligation, the fulfilment of which is a prerequisite for the proper performance of the contract and on the observance of which you may regularly rely (cardinal obligation). The liability for slight negligence is limited to the amount of the damages foreseeable at the time of the conclusion of the contract, the occurrence of which must typically be expected. This limitation of liability also applies in favour of our vicarious agents.

§ 14 Data protection

  1. In connection with the initiation, conclusion, processing and reversal of a purchase contract on the basis of these GTC, data is collected, stored and processed by the provider. This is done within the framework of the statutory provisions. The Provider shall not disclose any personal data of the Customer to third parties unless it would be legally obliged to do so or the Customer has expressly consented to this in advance. If a third party is used for services in connection with the handling of processing operations, the provisions of the Federal Data Protection Act shall be complied with. The data provided by the customer by way of the order shall be processed exclusively for the purpose of contacting the customer within the framework of the processing of the contract and only for the purpose for which the customer has provided the data. The data will only be passed on to the shipping company that takes over the delivery of the goods according to the order to the extent necessary. The payment data will be passed on to the credit institution commissioned with the payment. Insofar as the provider is subject to retention periods under commercial or tax law, the storage of some data may last up to ten years. During the visit to the provider's online shop, anonymised data that do not allow any conclusions to be drawn about personal data and do not intend to do so, in particular IP address, date, time, browser type, operating system and pages visited, are logged. At the request of the customer, personal data will be deleted, corrected or blocked within the framework of the legal provisions. Free information about all personal data of the customer is possible. For questions and requests for deletion, correction or blocking of personal data as well as collection, processing and use, the customer can contact the following address: Diagen Diamond, Keupstrasse 68. 51063 Cologne, Phone: 0(221)278 48 560, E-Mail: (Click here for more details DATA PRIVACY)
