You can only get our jewelry through our official sales platforms:

Avocadostore

If you buy through one of these platforms, you can be sure that you are getting fairly made original jewelry. 

Orders are processed very quickly. Write to us about what you want to change by replying to the order confirmation you received by email.

To exercise the right of cancellation, send us a message as soon as possible or call our customer service.

After your order has been processed, you will receive a confirmation by email.

Did you perhaps overlook the delivery time when ordering? A planned delivery time of 2-4 weeks is not unusual. We manufacture many of our jewelry pieces only on order. Especially the handcrafted collections require time. If you order several pieces with different delivery times, the latest date always applies, as we ship your order together as soon as everything is ready.

The planned delivery time is transparently displayed in several places with us: on the respective product page, in the shopping cart, and in the order confirmation via the "View Order" button. It is also visible in your customer account. Our jewelry pieces are created with great care, so we ask for a little patience. As soon as your package is on its way, you will receive a shipping confirmation with a tracking number.

All delivery times are carefully planned. However, especially during the Christmas season, occasional delays may occur. For example, if the gilding process takes a little longer or our shipping partner DHL delivers later due to the high volume of packages.

If the planned delivery period is exceeded, we ask for your understanding. We work closely with our partners and do everything to ensure that your jewelry arrives as quickly as possible.

If you have any questions about the status of your order, feel free to contact us at any time. We will check the current status directly in the system and assist you further.

GoGreen is a climate-friendly shipping and receiving service from DHL and Deutsche Post. The emissions generated by shipping are offset through investments in global climate protection projects. This way, our items can be delivered climate-neutrally through compensation.

Information about the respective delivery times can be found on the product pages. Do you want to know the exact status of your order? Just contact us. We are happy to help.

For standard shipping, the flat shipping rate for orders within Germany is €4.90. Here you can find information about shipping to many other countries.

If you order multiple pieces of jewelry with different delivery times, the latest date always applies. Your order will be shipped together as soon as all items are ready. If a partial delivery is desired, we can arrange this if possible. Please contact us early for this.

We ship with DHL Go Green. Of course, you will also receive a tracking number with the shipping confirmation.

Since we are not a large company, we produce in small batches with limited stock. Jewelry pieces that are in stock are usually shipped quickly. However, due to promotional activities, certain models can come into special focus, which may lead to them selling out quickly. For handmade jewelry, production takes a little longer because each piece is crafted with love and care. We always try to process your order as quickly as possible. If there are any delays, we will contact you directly and inform you about the option to cancel your order.

The difference between the brushed and the glossy finish lies in the finish of the piece of jewelry. Matte jewelry has a soft, rather unobtrusive surface that reflects less light and exudes subtle elegance. Glossy finishing, on the other hand, provides a shiny, mirror-like surface that reflects light more strongly and gives the piece of jewelry a striking look. Here you can see the differences.

For the production of our jewelry pieces, we use exclusively high-quality and durable materials, including 18k gold vermeil, 925 sterling silver, genuine gemstones, pearls, and enamel.

Of course, all our jewelry pieces are made from recycled, certified 925 sterling silver. For our cast models, like most designs from the Rosali, Ahimsa, Wildlife, and Calathea collections, the first handcrafted model is stamped once before it is cast in series. For handcrafted pieces from the Classics, Classics Mini, Enamel, and Capolavori collections, we forgo stamping. Our unique pieces consist of a combination of silver and tin. A traditional stamp would hardly be technically possible here, as it would actually require two separate fineness markings, and this step would significantly affect costs and delivery times.

We create our unique pieces using a special tin-silver soldering technique. In this process, 925 sterling silver wire is shaped by hand and then joined with lead- and nickel-free tin, which provides stability and a smooth appearance. Tin is durable, corrosion-resistant, and hypoallergenic: ideal for sensitive skin. Since it is 100% recyclable and often made from secondary raw materials, this technique is not only particularly artisanal but also a responsible choice.

Our most popular model from the Rosali collection is the 'Sina with Crystal', which we offer in two different sizes due to high demand. Roughly speaking: for a small and a large ear.

The 'small Sina with Crystal' is perfect for a small ear with a total length of about 2.4cm. The 'large Sina with Crystal' has a total length of about 3.5cm and differs in its ring circumference by about 3mm from the small model. The upper ring part can be optimized by gently bending it so that it comfortably encloses the ear without causing pressure points.

If you are still unsure, we are happy to help you in the Earcuff Guide.

Yes, Earcuffs can also be worn with hearing aids. Some of our customers even wear them with IdO devices (in-the-ear devices) in the ITE design, where the ear shell is almost completely filled by the ear mold.

The Earcuff is worn above the ear mold or slightly offset so that the fit of the hearing aid is not affected. Especially narrow or open models are well suited to remain wearable even with more complex fittings.

If you're unsure, feel free to send us a photo of your hearing aid and we'll help you find the right piece of jewelry.

Many of our jewelry pieces bear the engraving Nelly. Why this is, you can find out here.

Most people have a pronounced concha cavity, providing the earring with the necessary support. Additionally, the distance of the jewelry piece can be individually adjusted by regulating the upper ring part.

Not convinced yet? Check out our Earcuff-Guide. There you will learn how to insert and adjust the Earcuffs.

We recommend the models Hannah, Ronja and Ella for children's ears. On request, we also make the Earcuffs from our Classic Mini collection in a particularly small size; perfect for children's ears. A brief note in the shopping cart is sufficient for customization.

No, we do not operate a retail store. Our partner Jan can be found with his enamel and the Rosali collection at selected exhibitions.

We are sorry that your jewelry arrived damaged or defective! Please contact us as soon as possible via our contact form or by email and send us photos of the damaged or defective piece of jewelry. We will then find a solution together.

Sterling silver can tarnish over time, which is completely normal. Perfume, salty air, sulfur, skin creams, hairspray, and chlorine as well as the acidic pH levels of the skin can accelerate this process. How much the jewelry tarnishes (oxidizes) depends on various factors such as skin type and the wearer's care habits. To bring your jewelry back to shine, we recommend a silver polishing paste. More tips on jewelry care can be found here.

Jewelry pieces that are worn for a long time can be affected in their shape or structure by external influences such as impacts or improper handling. If your jewelry piece is bent or damaged, we offer repairs in many cases. Please contact us with a picture of the damaged jewelry piece. If a repair is possible, you can book our service here.

The service is offered in addition to our warranty and is not subject to the usual one-year warranty period. For all jewelry made of 925 sterling silver or 18k/24k gold vermeil, a one-year warranty applies. If a material or workmanship defect occurs within this period, we will of course replace your jewelry free of charge.

What we cover:

• fallen out stones or pearls
• Defective clasps

Break points that are immediately visible upon receipt of the goods or are due to a material defect (e.g., stress cracks or pre-existing material damage) are conditionally covered by our warranty. The prerequisite is that the defect is reported to us within the first 14 days after delivery is reported. Later damages that may have been caused by improper use or external influences are excluded!

What is not included:
Signs of use such as scratches or discoloration, natural oxidation, or changes caused by third parties are not covered by the warranty. In such cases, you are welcome to contact our Repair Service. We will gladly check if a repair is possible. Gemstones and pearls with inclusions and discolorations are natural and are not covered by the warranty.

Important for longevity:
Jewelry doesn't like chemicals. Avoid perfume, creams, or soaps, and store your pieces dry and separately. You can find more tips under Jewelry Care.

You placed the order yourself:
Send an email to kontakt@nellaundsina.de with a photo of the damage, a brief description, your name, and the order number. If your jewelry is replaced or repaired, the warranty will be extended by another year.

You received the jewelry as a gift:
Provide the name of the person who placed the order or the order number. Also send us a picture and a description of the defect. Let us know where to send a replacement piece.

No order number found:
Get in touch anyway. We will try to find the order. Without proof, the warranty does not apply, but maybe we can find a solution together through our repair service.

Fractures that are visible immediately upon receipt or are due to a material defect are of course checked by us. Please report such damages within 14 days after delivery.

Breaks that occur later are caused by external influences. Silver is a soft precious metal. If a piece of jewelry is bent too strongly, abruptly, or repeatedly (especially in a cold state), internal stresses can develop that later lead to breakage. This type of damage is not covered by the warranty. Our repair service will gladly check whether a repair is possible.

Did you order your jewelry from us in the last 6 months? Then you will receive a discount on the repair. Just send us a short email with your order number to kontakt@nellaundsina.de and we will check if a repair is possible.

Our Earcuffs stay in place due to their special shape and individual adjustment. To ensure they fit securely, they must be correctly adapted to your own ear shape. Since we cannot assist with the adjustment and the fit varies from person to person, unfortunately, we cannot provide a replacement in case of loss. If you have any questions about optimal adjustment and fit, we are happy to help.
