These are two Victorian or Edwardian enamel collar buttons or single cufflinks. Neither is marked but the small blue one tested 14K. The small blue enamel one has an inlaid leaf design. It appears that there was a seed pearl or small stone in the center but it is missing. I believe the leaf may be gold but I have not polished it. The back is 14K rose gold. It measures 3/4 of an inch long. The second button is large and heavy. It has an enamel bee or insect on top. I believe it might be made of sterling silver but it is not marked. It measures 1 inch in diameter. There is some missing enamel on one wing and possibly on the body. It has an age patina and may need polishing. I have not cleaned or polished the buttons. Please let me know if you have any questions. Thanks for stopping by.
