Frequently Asked Questions / FAQ

If the jewelry you ordered is in stock, you can make changes to your order until it has been packed and shipped. Once your order has been packed, you’ll receive a shipping confirmation email with your tracking number. In most cases, this means you can make changes until you receive this email.

If your jewelry is made to order, changes can usually only be made before it goes into production. Production typically begins on the next business day after you place your order.

You’re always welcome to contact us at shop@sisicph.com or by phone at (+45) 42 90 99 09.  We’ll always do our best to find a solution that works for you.

We accept all major debit and credit cards, including Visa and Mastercard. You can also pay with Apple Pay, Google Pay, and PayPal.

If your jewelry is made to order, a special order, a wedding band, or a bespoke design, it will be made especially for you. These pieces require production time, so the estimated delivery time will vary depending on the product you choose.

For these orders, the amount is reserved when you place your order, but payment is not charged until your jewelry is finished and ready to be shipped.

Please note that some banks limit how long a payment can remain visible as reserved in your account. If the reservation no longer appears in your account overview, this does not affect your order, and payment will still be collected once your jewelry is ready.

If the price of your jewelry is reduced during this period or it becomes part of a promotion, you can request a refund of the price difference. Simply contact us within the 90-day period, and we’ll take care of the rest. Read more here.

We offer one complimentary ring resizing for our diamond rings within 3 months of purchase, so you can make sure your ring fits comfortably.

If your ring is significantly too large or too small, we recommend that you avoid wearing it. In these cases, exchanging it for the correct size is often the best option. To be eligible for an exchange, the ring must be unworn and show no visible signs of wear.

We’ve created a detailed size guide to help you find the right ring size or necklace length. Read our size guide here.

Helpful tips if you’re unsure which ring size to choose:

• Choose one of the standard sizes available in our collection. This makes it easier to resize the ring or exchange it for another size if needed.
• If you’re between sizes, we recommend choosing the slightly larger size. This generally gives the best result if the ring needs to be resized later.

Yes. We offer one complimentary engraving on all of our diamond rings.

If you’re unsure about the ring size, we recommend waiting until you’re certain the ring fits before having it engraved. This avoids the need to redo the engraving if the ring needs to be resized.

Please note: Once a diamond ring has been engraved, it is considered personalized and can no longer be returned or exchanged.

As part of our satisfaction guarantee, we offer one exchange per wedding band.

Your exchange can include several changes, as long as they are requested at the same time. For example, you can change the profile, width, thickness, or surface finish. If the new ring has a different price, the difference will be adjusted accordingly.

If you choose to exchange your ring for a new one, production will begin once we have received the original ring. Our standard production time for classic wedding bands will then apply. Read more about our satisfaction guarante here.

Returning Your Wedding Band

You have 30 days to return your wedding band from the day you receive it.

As each wedding band is made especially for you, 5% of the purchase price will be deducted from your refund. This covers the cost of remelting the gold as part of the return process. You will therefore receive a refund of 95% of the original purchase price.

If you use our return label, an additional return shipping fee of €9 will be deducted.

In most cases, your wedding band can be resized by our goldsmith. This is usually the quickest option, and your first resizing is complimentary. It usually takes 10–15 business days to resize the ring, starting from the time we receive it.

If the ring is significantly too large or too small, exchanging it for a new size may be the better option. In this case, we will make a new ring, and our standard production time of 4–5 weeks will apply.

If you’re unsure which option is best for you, you’re always welcome to contact us.

We’ve created a detailed size guide to help you find the right ring size. Read our size guide here.

Yes. We offer one complimentary engraving on all of our classic wedding bands.

We recommend adding the engraving when you place your order, as this is the easiest and quickest option. Any future adjustments can be made while keeping the existing engraving intact.

If you prefer to have your wedding band engraved after receiving it, we’re happy to help with that as well. In many cases, the engraving can be done at the same time as an exchange or resizing.
