Sarah was absolutely amazing to work with

Sarah was absolutely amazing to work with. Great communication and the ring I purchased far exceeded my expectations. Even the best photos can't capture how gorgeous the ring is in person. My now fiancee has been getting constant compliments on her ring. I highly highly recommend Coastal Diamonds!!

I would 10/10 recommend Coastal Diamonds LLC.

The sweetest owners. There's not another business in our area who offer what they do along with the customer service that they provide. I would 10/10 recommend Coastal Diamonds LLC.

Sarah and her team at coastal diamonds are an awesome up and coming jewelry company!

Sarah and her team at coastal diamonds are an awesome up and coming jewelry company! She went above and beyond finding my wife a beautiful diamond engagement upgrade for a very affordable price. The downside is now I’m blind and Hannah can no longer lift her hand from her side. The clarity and beauty of the ring we got is unmatched and as long as you don’t mind losing your eyesight or having the inability of using one of your hands then Sarah and Coastal Diamonds is truly the team to help you!

Working with Coastal Diamonds was a dream!

Working with Coastal Diamonds was a dream! I was extremely happy with the communication, customization, and customer service that I received. I was also pleasantly surprised to see the cost was much less than a big box store. I will be back for more in the future! Jon and Sarah take pride in their work and are trustworthy.

I recently purchased an engagement ring from Coastal Diamonds and I couldn't be happier with my experience. The ring itself is stunning, with an exquisite diamond that truly stands out. The craftsmanship is impeccable, reflecting the care and skill that went into its creation.
What impressed me the most was the custom design process. They worked closely with me to ensure the ring was exactly to my liking, and they absolutely delivered. The attention to detail and willingness to tailor the design to my preferences made the ring even more special.
Additionally, the delivery was quick and on time, which was a huge relief. They also sent all the paperwork verifying the diamonds authenticity and appraisal. I highly recommend them for anyone looking for a beautifully crafted, custom-designed engagement ring. Their exceptional service and quality make them stand out from the rest.
