Amazing experience
I bought a gold necklace and the price was considerably better than in other online stores. Their customer service is impeccable, they've answered all my many questions quickly and taught me a lot about gold jewelry in the process. I have never seen a business get a 4.9 score out of nearly 1k reviews, but they certainly earned it. I bought a gold necklace and the price was considerably better than in other online stores.

I had a design for a pendant that I wanted to have custom made, and the goldsmith worked with me wonderfully to bring my vision to life. The result is a beautiful pendant that has a lot of sentimental value to me. The craftsmanship and personal touch attention were top. I can highly recommend this jeweler/goldsmith!
