I am writing this letter to thank Zivko for my extraordinary new diamond 3CT ring. The design is beautiful and I am always being told how it shines! I want to thank Zivko for always being available when I had a question about the ring and how he helped me to size it perfectly so I felt comfortable wearing it. I look forward to my next jewelry purchase. I know it will be just as remarkable!

I'm excited about my new custom diamond earrings crafted by "Z" the Jeweler! Collaborating with Z to conceive an amazing and unique design has made them a particularly special addition to my growing collection of his work. Being a part of the process to bring this design to life brings an extra bit of joy every time I wear them. I have known and worked with Z for many years. His honesty and integrity keep me going back for my fine jewelry pieces.

Zivko has made my wife’s engagement ring as well as other custom jewelry pieces for four of our sisters and brothers, who were all extremely pleased. Zivko is an amazing, honest, and caring person. He makes stunning and superior quality jewelry, and I would highly recommend him. He has been our family jeweler for over 25 years. My family and I are grateful for Zivko and will continue to buy from him. There is no other jeweler in existence and for very good reasons. We highly recommend him.

My daughter Nicole has just delivered to me (in Boston) the diamond earrings that you made for my fiancée, Avis, and tells me that you were also responsible for putting together the 3-diamond ring I gave her a while back. You do lovely work, and Avis has received many compliments on the ring. The earrings are similarly outstandingly beautiful, and I hope to give them to her on our upcoming trip to Europe. It must be nice to have the skill to do this exquisite and happy work. Thank you again for your help and for getting it done with such short notice.

Zivko is an amazing jeweler. He made us the most beautiful engagement ring. We were so happy with his work that we asked him to make my anniversary gift, which were a pair of stunning diamond earrings. He’s since made many more pieces for us and we’re always impressed. His attention to detail and craftsmanship are impeccable and the sheer artistry of his jewelry is astounding.

Zivko has been my jeweler for over 20 years. His unique design and approach have resulted in timeless pieces that we will pass on to our children. His attention to detail and ensuring customer satisfaction is his priority. I highly recommend him so much so that our family and friends have also turned to him for their jewelry needs.
