These beautiful birthstone charms will add a wonderful glimmer to your glass lockets! Please write to me if you need more of any certain birthstone, I may have extra in stock. I will automatically pack the 5mm diameter size, unless you write to me before paying and request the 4mm instead in writing. Color hue may vary based on the screen view and electronic display device. These birthstones were purchased in 2013 directly from Origami Owl, in two sizes. The stock and coloring may have changed in five years on the O2 website and products, which I have no control over in my pre-purchased stock. Thanks for communicating to avoid the wrong size mailed out. The high-end floating charm brand here in Hawaii is called Tropicool Hawaii Jewelry. It has other designs with a more tropical theme than O2. Please check out my charms stock for some great deals! I normally mail out within 72 hours of receiving payment, except on Friday and Saturday. Any payments received on Friday will be mailed out on Monday, unless it is a holiday, then it will be the next work day. Other unforseen events, such as illness or family emergency, may hinder the speediness of the delivery. Please write to me if you do not receive your item within a week of payment made, so I can check with the local post office for theft or misplacement. Hawaii takes an extra 1-2 days for shipping and I appreciate your patience. Please let me know if you are bidding on another item from my site so I can ship them together! Thanks and Aloha! Returns:**Please write to me if you have any questions, I will solve any problem you may have with your order. Please do not leave feedback until we have discussed your problem with me in eBay messages. I accept returns, seller pays shipping, after a message in ebay messages is sent to me, describing why a return is requested. I will send you a return address to mail the item to, using the same shipping method as I used to mail it to you in the first place. As soon as I receive the returned item in the same condition as when I mailed it out, I will issue a refund to customer's paypal within 3 days of receiving the item. I will send a message to let you know I recieved it as well. I will leave good feedback for customers if good feedback is left for me.
