I think your shop looks great! Sorry I can't buy anything, but if I could I would choose a pendant. I used to wear a violin peg as a pendant when I was growing up. I liked the feel of the smooth wood.
So, I would include info for each and every item stating how big it is. Hard to tell from the photos and buyers need to know.
Plus, there is this thing called SEO and basically it means everything should be tagged and titled to make it easily found in a search. Just make the title what it would be in a search
pendant, wooden pendant, handmade wood jewellery etc are all good titles but "Segmented purpleheart and maple pendant." is not something folks would type into a search engine.
