The professionals at Duncan Diamonds and fine Jewelry always help me choose the most exquisite gifts for my family. I always feel like I am dealing with family and what I most like is that there is never any pressure to buy. My last purchase was done remotely and once again they have exceeded my expectations.

My husband and I went in to have a ring designed with my diamond and my mother in laws diamond from our engagement rings. They we’re really helpful with ideas and spent time looking and going over the details. We can’t wait to see the ring when it’s done!!

I just love, love, love the 110% customer service all the time from all the staff. Especially Mike Sr. I’ve come to him several times with my crazy ideas for some custom jewelry. He never ceases to amaze me with the final designs he ends up mastering. THANK YOU!!!!

I had a broken sterling silver link bracelet that broke after many years of wear. I wanted to use the silver in my next bracelet and so took it to Duncan Jewelers and explained what I wanted. I picked it up today and was absolutely thrilled!!! A bit more expensive than I would’ve expected but it was worth the price to have it hand-made based on my design.

Duncan Jewelers have provided superior, quality service to me each time I walked in the door. Knowledgeable and friendly staff. Their jeweler was able to custom design a piece for a vintage watch I own and did an amazing job. I highly recommend this family owned business for all your retail and specialty jewelry service needs.

My wife and I had a wonderful experience shopping with Mike and Lacey. We felt right at home and loved their selection of Diamonds and Sapphire's. They had everything I needed for my wife's birthday week! I plan on buying more jewelry and a set of knives there. It's great to have them at the Lake! Thank you to all......see you soon!
