This is a wonderful place to do business with. I searched high and low to find the perfect blue tourmaline gift for my sister's birthday. Susan was very patient and professional. She walked me through the selection and design of making a custom piece. I received pictures and emails all during the production, presentation and shipping processes. The gift was a hit with my sister and everything done according to my specifications.
I might add this custom piece was very reasonable and not beyond the cost of jewelry pieces already made up on the website. I am extremely pleased and would do business again with this merchant. Well done and thank you Coastal Jewelers.

We recently worked with Susan on a custom diamond ring that I had been wanting for as long as I can remember, so this was a big event! Susan was knowledgeable and nothing was too much trouble and she soon got to work sourcing and designing the ring. The whole process was very easy and I have to thank her jeweler for setting the ring so quickly towards the end of the process ensuring that I could wear the ring to an event earlier than planned. I would 100% recommend Coastal Jewelers

My husband and I got our wedding rings at Coastal Jewelers and they were AMAZING to work with! Susan was so helpful in getting us exactly what we were looking for, and they were made so quick! I also got my engagement ring resized and polished before the wedding and they all looked amazing! They were so friendly and we cannot recommend them enough! Such a beautiful store!

My husband and I had such a great experience at this jewelry store. They had such a great selection to choose from. We ended up buying a few items and we are very happy with our purchases. Susan, the owner, and her sister were extremely nice to work with. We will be back. :
