How long does a MÜZCINA ring take to arrive after my order has been placed?

After your payment is processed, within 3 days you will receive a MÜZCINA Finger Size Verification Kit via UPS.  The kit will include a range of finger sizes matching the LUXE or LITE profile you have selected with your ring and a confirmation code to be entered into the Finger Size Verification Screen (add 3-4 days if a rapid prototype resin model is requested).  This is how we can be sure your ring has an ideal fit and also verify the size in order to qualify you for the FOREVER WARRANTY.  The kit will be shipped to the address you indicated at the time of checkout. Please verify your correct finger size with us as soon as possible.  We will begin manufacturing your ring, only after a finger size is verified by you.  Meanwhile, within hours of placing your order we will have already begun to allocate metal, diamonds and human resources for the selected style you have chosen.  Your MÜZCINA ring will arrive within 2-3 weeks after your order is paid and you verify your finger size.

What is a rapid prototype resin model?

This is a dimensional and feature accurate representation of the ring you ordered in size 10.  It’s made from photo-polymer resin using Virtual Simulation Machining duplicating all the same base features and cuts that your ring will actually have in size 10.  The resin is made in size 10 because we would not yet have your size verified.  When you decide on the model you like best,  at the time of checkout in the special instructions field, you can request that we provide you with a rapid prototype resin model in order to confirm that you like the feel of the actual ring with dimensions that you ordered.  It may come in a variety of different colors and will have one edge that is unfinished but will otherwise have the same dimensions and features of your ring.  It will be shipped together with your MÜZCINA Finger Size Verification Kit.

How many rapid prototype resin models can I order?

We include 1 free Rapid Prototype resin with your ring when it is paid in full and when you request it in the SPECIAL INSTRUCTIONS field at the checkout.  Additional models are provided at USD $150.00 each including shipping after your ring order has been paid.

What if I am getting married this weekend and need a ring in a RUSH?

We understand that sometimes life comes at us fast, and there is not much time for planning.  So, if you find yourself in a time crunch and need a ring quick, don’t worry, we can help!  We do RUSH orders. Depending on your finger size and the metal you choose there may be a small premium charge (5-10% additional cost) for a RUSH order.  Just let us know in the special instructions field at the time you place your order.

What if I don’t want, or do not have time to confirm my ring size?

While we do not recommend this, it is possible for us to make your ring based on US STANDARD finger sizes.  If you know this information you can verify your size immediately after checkout.  However you will not have the confirmation code sent with the Finger Size Verification Kit and will not qualify for free sizing included with the FOREVER WARRANTY.   As soon as your finger size is verified by you, we will begin the manufacturing process.  If you require a RUSH order please notify us of your situation in the special instructions field at the time you check out.  RUSH orders may subject to a RUSH order charge (5-10% of total price) depending on finger size and setting style.

I have allergies to different metals, do you make rings with hypoallergenic metals?

Yes, most often allergies are not to pure precious metals such as pure Platinum and Pure Gold, but rather the alloys they are mixed with when made into 14K and 18K.  Nickel is usually the culprit in allergic reactions to metal.  If it’s white metal that you are looking for, we recommend that you NOT choose our 14K or 18K White gold as it contains high concentrations of nickel.  Platinum would be the best choice for a bright white color.  This metal is made of 95% Pure Platinum and 5% Ruthenium (a platinum group metal).  A second option would be 18K Gunmetal Grey Gold.  It is made with 75% pure Gold and 25% Pure Palladium and Pure Silver with proprietary trace elements for durability and color.  18K gunmetal grey gold contains NO nickel and is Hypoallergenic.
14K Gunmetal Grey Gold, 18K Yellow Gold, 18K Red Gold, 14K Yellow Gold and Silver also contain NO nickel.

Don’t see exactly the ring you like but still want a ring with the same quality manufacturing and FOREVER WARRANTY as MÜZCINA?

No problem, we can make a ring to your specifications or can help you design one.  We also work with a variety of CAD files and drawings.  Just send us any digital files or pencil sketches you have to together with your contact info and we will get back to you within 24hrs.


What if I change my mind after receiving my ring or I don’t like the ring I ordered?

If you are not completely happy with your ring after receiving it, please contact us ASAP by phone at 1-888-684-7775 or by email at  After informing us of your intentions, simply return the ring to us within 7 days of receiving it in its original condition. You will be credited the full cost of the ring towards a different style, less the costs for rapid prototyping the replacement ring model which will be sent to you prior to a new finished ring being manufactured. We must insist on rapid prototyping your second ring first, in order to be sure to get it right the second time around.   You will need to follow the instructions found below under SHIPPING in order to return your ring.

What if I change my mind, and want my money back after checking out?

This is where we really strive to keep you happy and coming back to us when you are ready to try again.  As our ordering process involves a two steps, there are a couple things that take place before we begin manufacturing your ring and a few different scenarios which might play out depending on WHEN you cancel your order. So, please contact us as soon as possible if you want to cancel your order!

1. If you change your mind after paying and we have not sent the MÜZCINA finger size verification kit to you yet, then we will refund 100% of the full amount you have paid.

2. If the MÜZCINA finger size verification kit has been shipped then we will deduct USD$70.00 for this kit and USD$150.00 for Rapid prototyping if a prototype resin was requested, then refund the balance back to you.

3. If you have paid the full amount of your ring and you have verified your finger size with the MÜZCINA finger size verification kit and the ring has been made but not shipped out yet, then we will refund the amount paid less $70.00 for the MÜZCINA FINGER size verification kit + USD$150.00 for rapid prototyping (if a prototype resin was requested) and a scrapping fee of 20% of the price paid.  In addition we will discount all actual shipping charges incurred.   The scraping fee is to cover our costs associated with manufacturing your ring, then having to melt it down and recycle the metal and diamonds (if applicable).  Unfortunately we must charge this fee as there are hundreds of thousands of different combinations of rings that can be made from sizes 4.5-16 and the fact is, your ring will be melted down and refined if you cancel your order at this point.  If you’re not sure about the style you have selected or want to try on a rapid prototype resin model of your ring before committing to any particular style, please request one in the additional notes at the checkout.  1 Prototype resin model of the ring you purchased is available by request in size 10 and is FREE when it is requested at the checkout and after your payment is received.


Can MÜZCINA rings be sized?

Yes, but depending on the stone arrangement and the amount of sizing up or down the ring may need to be remade.  Please refer to the FOREVER WARRANTY and also below in SERVICE section for additional details.

Who pays for shipping?

For after sales service, JJBückar will pay for ALL return freight costs.  You will have to pay for all shipping expenses back to your residence or business.
Can I have the surface finish re-applied to my ring if it wears out?
Yes, the following surface finishes can be re-applied: Polished, Brushed, and Stone.  These finishes are covered twice under the Forever Warranty.
Can my MÜZCINA ring be sized by my local jeweler?
Depending on the style, size and whether your ring contains diamonds, sometimes MÜZCINA rings can be stretched or compressed up to ½ size (up or down) from the original finger size by your local jeweler.  However we do not recommend this as your FOREVER WARRANTY will be void if a third party alters or services your MÜZCINA ring in any way.

How often should I take my ring in for cleaning or polishing?

Your ring will gain its own patina from scratches dings and dents as it experiences the good the bad and the sometimes ugly moments of life on your finger.  We call this character.  Please don’t mind the fact, that like people, precious metals will show their age.  With wear, the surface of your ring will become work hardened above and beyond the hardness it was delivered to you with.  While having your ring cleaned periodically or every few months will not hurt it, we do not recommend polishing or refinishing your MÜZCINA ring more than 2 times during the course of ownership. When you are ready to have your ring refinished or are passing it down to your heir, please contact us and we will refinish, polish and service it twice under the MÜZCINA FOREVER WARRANTY at only the cost of shipping it back to you.

I lost a diamond and would like to replace it myself, can you send me a replacement diamond or can I get it from a JJBückar retailer?

All diamonds are robotically set in a MÜZCINA rings, then checked for quality under 10X microscope.  As every diamond is precision cut to ideal standards and set identically each time, according to its prearranged setting, we make every effort to ensure that stones will not fall out.  However, we can set thousands of stones each day and occasionally it happens that one may fall out.  If this happens, please return the ring to the store it was purchased from or otherwise send the ring back to us together with an RMA form filled out.  We do not sell or send individual diamonds directly to consumers.  If you break or chip a stones they can be replaced up to 3 times at only the cost of shipping the ring back to you.
