    I got this charm to go with the forget me not locket. All arrived well packaged and promptly. Really nice crystal and great size, dainty but not tiny. Seller was great and fulfilled a request regarding crystal no probs.

Processing time starts after your order is placed and if I have received all the information necessary to make your order. Missing info can delay the shipping. The processing time stated in the shop might vary slightly and take a few days more during the holidays and other busy seasons like Valentine's day.

Orders from LATINOAMERICA and AFRICA (except South Africa) please convo me before purchasing. All Center and South America, Africa and some Asian countries are subject to cancellation or a $5 more shipping cost to provide an upgraded secure shipping (especially Mexico and Rep. Dominicana). Packages to Latinoamerica usually take around a month to arrive. International orders usually take 7-10 working days to arrive. Sometimes a little less and sometimes a little more from the estimated date depending on where you live, the weather, holidays,... Delays in shipping are rare but I have to say this because they can occur. Please be patient and understanding if this is the case as these are circumstances beyond my control. If you think your order is taking too long please count the working days before contacting me and if you think it's taking longer than should or if there's a problem please, contact me so I can solve it.

If it exceeds this time, please contact me. You must contact me within thirty days since it was sent. Due to bad weather during the winter there can be delays. Delivery time may be delayed during peak holidays season. I will put a message in the shop if this happens.

CHRISTMAS ORDERS: Please order with time if you need it by Christmas. 90% of times it takes just 7-10 working days to arrive but sometimes it can take a little less or a little more. I can only give estimated dates as I don't give it on hand so I have no way of knowing how long exactly it will take for each package to arrive. It depends on the post. Orders after Dec 12-14 will most probably arrive after Christmas. I do not guarantee any deadline or shipping delivery time since I'm not the post. Thank you for your understanding & Happy Holidays!

- Wear your Sterling Silver Jewelry often. Your body’s natural oils will actually help prevent tarnish on pieces.
- Aluminum jewelry along with sterling silver are the two metals with less skin reaction. It may become dull or dirty over time but it can easily be cleaned by gently washing it with a mild soap or dishwashing detergent, a sponge and hot water or even better with a simple chamois cloth (no need of water). Be careful when cleaning so they leave no scratches and the most important is to dry it very well. You can also use a blow dryer or a dry cloth for this. The chamois cloth is recommended and the fastest and easiest way. Polishing jewelry clothes are not recommended for aluminum.
- Chlorine and even vinegar can damage your jewelry. Although sterling silver can get underwater it's never recommended to do so with any metal. Avoid getting your jewelry wet, except when cleaning the piece. Don't put plated items underwater or any product that can alter the piece.
- Store your jewelry in a cool, dry place. Do not store jewelry in the bathroom. When not in use, is better to store your jewelry in its bag/box or a sealed plastic Ziploc bag (separate from other pieces to prevent scratching if possible).
- Apply any perfumes, lotions, makeup, etc and allow them to dry completely before wearing your jewelry.
- It's recommended to put your jewelry after putting clothes on. If a piece of jewelry gets attached to your clothes don't pull from it strongly. Same as if it gets knotted up when storing it. Try to unknot it with a plier or similar very carefully as to not break or open any component. If this happens, contact me to find a solution.
- To preserve the color of the nylon cord jewelry items, prevent putting them under water.
- To clean Sterling Silver use a polish cloth or wash your pieces in soapy warm water to remove any dirt. Non-sterling silver items can be washed carefully with a wet cloth or with just a chamois cloth.

/// * Items on sale are excluded from any other promotion, coupon code or free shipping. Coupon codes must be applied at checkout. No refund will be given if it is not applied.

You will get one free jewelry piece of your choice up to $25. Shipping is not included. If you want to get free shipping your total purchase (item+shipping) must not exceed $25. If you want an item of less than the top amount the difference won't be saved for a future purchase. Please don't make a purchase of the free item, you must message me before any purchase is made to get the free item. The number of points needed to get the reward can be changed if I see the numbers don't add up. It will not affect you if you have a card with points left. Only the new card you get after you finish one will have the number changed. Free item can not be returned or exchanged.

Since those items are created by hand, they can vary from the image shown and sometimes they are not perfectly centered, aligned,... because of this but any variation adds character to the piece so it can't be considered as a defect. Please, note that hand stamping leaves an imprint through to the opposite side of the item because I have to use pressure when stamping so I prefer to only stamp on one side. Each letter is hand stamped individually so no two initials/words will be exactly alike. I don't darken hand-stamped pieces unless it's requested for an additional price. Rings: soldered rings can vary in one to three millimeters from size (less than 1/4 a size) and should be considered normal as it's a handmade piece and after hammering the final size can change these few millimeters depending on how many times it's hammered and the metal expanded.

All of my chains and a lot of my charms are made from solid .925 Sterling Silver. This means they contain 92,5% of pure silver. You will see they are usually marked with 925 or STER. My chains are not rhodium plated, white gold plated, nickel silver or silver plated. I use some rhodium plated charms because this is a good material that lasts a lot and it does not wear off with use easily. All plated items can wear off eventually with use and the time will depend on the person and use (time depends on the reaction to body chemistry). Sterling silver and aluminum do not wear off and can be cleaned easily. I use pure 1100 food safe aluminum blanks and from time to time they can have little marks resulting from the machine cutting from large plates that will make your piece more unique and special so it should not be considered a defect as it happens with all metal but if it has large marks I won't use it. I test all my pieces to ensure the best quality. If you have had a skin reaction to any plated material it is better to go with solid materials like sterling silver.

I use the same sterling silver chain in all my pieces with a slight size variation in the ones the charms have to go through the chain so one is a 1,2x1,5mm and the other a 1,7x2,2mm chain. Please keep this in mind if the image has not been updated. It's the same chain and the difference can barely be appreciated in the pictures but I'm updating them once at a time. My jewelry can change prices due to the changes in the price of sterling silver in the market.

All my gemstones are natural genuine semi-precious stones otherwise noted in the listing description. Due to their handcrafted/ hand-drilled nature, no two beads or pearls are exactly alike. Size, shape, and color might vary due to the nature of the gemstones and photograph and monitor color settings.

I love to do custom orders so if you would like something with more charms, birthstones, more quantity or length please, contact me. I will be happy to prepare something special for you.
