Hello @elementaltreasure and welcome.
Don’t be discouraged. It can take a few months to get established on eBay, and it has only been about two weeks so far for you. Your listings are good, and if one’s items are well-priced and in demand, the sales will follow.
I agree with the other poster, you need to include more details about the items in your Item Specifics too. It may seem redundant to repeat descriptors in the title, IS, and Description fields, but each plays a role in Search Engine Optimization. Include things like size, color, gem type, weight, etc.
In addition, just food for thought—unless you are planning to list a lot more than the current 28 listings, opening a store may not have been a necessary expense. Sellers can get up to 250 free listings a month without a storefront.
Be sure to keep abreast of what your competition is doing. Make note of the most successful sellers in your field for comparison.
For example, i see many who sell similar items have listed their choice of category as Collectibles> Rocks, Fossils & Minerals>Crystals & Mineral Specimen> Crystals which is slightly different than yours. Sometimes that small difference in category can improve sales. (Just something to experiment with.)
Your shipping time may work against you as an international seller. Shoppers usually want fast shipping, but you can compensate for this by offering better customer service and/or value for money, for example. And whatever you can do to improve shipping times will be to your benefit. You might consider having one-day handling, for instance.
Wish you much success, and please come back anytime you have a concern.
