Engagement Ring Search?

Picking the right engagement ring can be quite daunting. Stuller, my favorite American supplier of engagement rings, not to mention gemstones and jewelry supplies, now has allowed me to let my customers see their entire inventory right on my website. You will have the option to see the many hundreds of styles they sell, plus preview your ideas by selecting a style, size, metal, and gemstone(s) to create an image of the finished product. You can request a quote, which they will send to me as their partner. If you see something that you would like modified, they can do that also! Click HERE to try it out.


Clip-On Earrings - No Problem

If you would like a particular design of one of my earrings as a clip-on rather than a post or ear wire, I can make that style for you. Please just contact me to discuss.


Custom Design Appointments

I am meeting with customers again at the studio! I am not requiring masks but am happy to wear one if you like. If you are interested in working with me on a custom design, please contact me to make an appointment. If you prefer, I can meet with you by phone or we can meet online using Zoom or Facetime.

"Arrived quickly and beautifully crafted! Delicate, yet strong. I will definitely be making more purchases in the future."  

" Such a lovely ring & Cathy was a joy to deal with! I really appreciate the time she took to thoroughly answer all my many questions which was extremely helpful during the custom order process. I bought this as a gift for my Mom and gave it to her yesterday....She loves it and it fits her perfectly :) Would absolutely buy from this shop again and I recommend this seller to anyone looking for a special, well-made piece of jewelry. Thanks so much for a great experience." 

"If I could give Cathy 10 stars I would! This was a birthday present for my sister and she was great about holding the earrings and shipping them a week before my sister's birthday. She also changed the wires for me b/c of my sister's metal allergy and Cathy was super pleasant. It sounds like the gift was wonderfully wrapped as well. Would definitely purchase from her again!" 

Designing Jewelry Long Distance - A Testimonial

During this period of self-distancing and quarantines, I can still work with you to design something special! By phone, email, or face-to-face software, we can work together easily and safely. Here's the proof:

"After some initial discussions, via telephone, I decided that a ring might be the best choice. Cathy and I worked via phone and email, as well as Facebook during the process. After deciding on a ring, Cathy called me and we spoke at great length about my daughter, her likes and dislikes in jewelry as well as mundane things like ring size. She forced me to think. 

I provided pictures of my daughter so she could see her and the kinds of things she wears. Armed with that information Cathy went away and came back with suggested designs. I was floored! I could actually see my daughter wearing any of the possible designs. It was amazing! Over a period of a few weeks, the design was refined and I selected the option I liked best. 

The finished rings were outstanding and my daughter loved them. ... In a way, Cathy got into my head and brought out the perfect gift. Trusting Cathy with this important gift was the best thing I did! All of the things that one might think of negatives were not; long distance communication, no input from my very selective daughter, and ring design when Cathy had not ever met my daughter. It all worked out. ... My daughter loves her rings ".
