  1. Scope

These General Terms and Conditions of Sale (hereinafter the "GENERAL TERMS AND CONDITIONS") apply to the exclusion of any other document, to all purchases on your own behalf relating to MESSIKA products (hereinafter the "Products" or "Product") made in one of the stores operated by MESSIKA SWITZERLAND SA (hereinafter the "Store"). Any contrary condition invoked by the Customer shall, in the absence of express acceptance by MESSIKA SWITZERLAND SA, be unenforceable against MESSIKA SWITZERLAND SA. However, special conditions may apply to a specific transaction or offer offered to Store Customers, which shall prevail in this case over these GENERAL TERMS AND CONDITIONS.

These determine the rights and obligations of the parties in the context of the sale of Products (hereinafter "the Sale").

These GENERAL TERMS AND CONDITIONS are not intended to cover purchases of products made on the MESSIKA website.

These GENERAL TERMS AND CONDITIONS do not apply to sales of tailor-made products, which are governed by special terms and conditions that are communicated on this occasion and are available on request.

Sales made in this context are reserved for individual consumers only (the "Customers") and any purchase for resale in a professional context is strictly prohibited.


The applicable GENERAL TERMS AND CONDITIONS are those in force at the time of the sale.


  1. Identification of the offeror

MESSIKA products are sold by the company: MESSIKA SWITZERLAND SA with share capital of CHF 100,000, having its registered office at c/o Mazars SA, Chemin de Blandonnet 2, 1214 VERNIER, Switzerland, with federal number: CHE-308.249.639 and registered with the Trade Register under number CH-660.0.443.019-7 (hereinafter referred to as "MESSIKA").


  1. Products and display of prices

The essential characteristics of the Products and their prices must be specially labelled or displayed in the Store.

The price of the Products is shown in euros inclusive of all taxes, including value added tax at the statutory rate in force.

Any purchase of a ring smaller in size than 48 or greater than 60 shall be treated as a customer order as defined in Article 6 "Returns". Customer orders must be the subject of a prior quotation and cannot be returned (see Articles 6.2.2 "Non-returnable products" and 6.4.1 "Conditions for issuing a credit note").

MESSIKA reserves the right to limit the quantities of MESSIKA products purchased by a Customer and/or refuse any abnormal transaction or one placed in bad faith, provided that this constitutes a "legitimate reason" within the meaning of Article L.121-11 of the French Consumer Code.


  1. Payment terms

Purchases must be paid for in full on the day of purchase, directly in the Store.

The Customer may pay for MESSIKA products in cash, by credit card or by bank transfer.

Payment by cheque is not permitted.

In the event that, for any reason whatsoever (objection, rejection by the card issuer, etc.), the sums owed by the Customer cannot be debited, the purchase process will be cancelled. MESSIKA will not hand over the product to the Customer until the Customer’s payment has been approved.

The Customer warrants that it has the necessary authorisations to use the payment method chosen when paying for the product.


4.1. Cash payment

The store accepts cash payments as long as the amount is compatible with the statutory thresholds in force in the country at the time of purchase.

Any payment of an amount exceeding the statutory thresholds in force must be made using cashless payment methods (payment card or bank transfer).


4.2. Payment by credit card

We accept Visa, Eurocard/Mastercard, American Express, China Union Pay, Japan Credit Bureau, Diners, Discovery, WeChat Pay, Alipay and Twint.


4.3. Bank transfers

We accept payments by bank transfer received in Swiss francs to our bank account domiciled in Switzerland.

MESSIKA's bank must confirm receipt of the transfer before payment can be deemed to have been made.


4.4. Payments in instalments financed by HeidiPay

Messika gives private customers the ability to pay in several instalments (hereafter the "Financing"), thanks to our partner HeidiPay, under the conditions defined below:

- The customer must have a Visa, Mastercard or American Express bank card issued by a Swiss bank and valid for more than one year;

- The amount of the Financing must be less than CHF 15,000 (including taxes);

- The customer must be a Swiss resident and have a Swiss identity card, a Swiss passport or a Swiss residence permit type B or C issued more than 12 months ago;

- Only MESSIKA jewellery and accessories can be financed by HeidiPay; delivery and after-sales services are excluded from the Financing 

It is specified that HeidiPay's decision to accept or reject the Financing application is subject to banking secrecy, as Messika does not have access to this information or to HeidiPay's acceptance criteria.

If the Financing is accepted by HeidiPay, its execution is subject to the customer's acceptance of the credit agreement proposed by Alma.

The staggering of the corresponding repayments will be made by the customer exclusively to HeidiPay.

If the financing is rejected by HeidiPay, the customer will be able to pay cash using other payment methods offered by Messika (articles 4.1, 4.2 and 4.3 of the present document).
