We are proud of the jewelry services we have provided to Sammamish, Issaquah, and the surrounding community over the years. Chances are we have serviced the jewelry of a loved one or neighbor. Ask them how we did.
We would love to design, repair, provide jewelry appraisal, or refurbish your cherished jewelry. And if it is time to upgrade the diamond in your ring or re-imagine some inherited jewelry we can help with that, too.


We like to say that making jewelry is easy – we do it everyday. Deciding what you want is the hard part.
Our jewelry designers can work with you to create a custom jewelry piece that is incomparably yours. Whether you’re starting from scratch on your custom jewelry project or working with diamonds and gemstones that have been passed down through the family, we can turn your jewelry dreams into reality.

If you have an idea of the type of jewelry you want – great! Let’s get started! If not, we can help you figure out the best design for you. Once we settle on a design we will give you an accurate estimate of the cost. When you are ready to get started we ask for a deposit of half with the balance due upon completion – usually 4-6 weeks from the time we start. We work in any metal. Come to us for your custom engagement ring needs if you’re in the area from Sammamish all the way to Issaquah, WA.

We can also remake your vintage pieces into old-looking new jewelry with all the practicality that comes with a new piece of jewelry.

Here at Plateau Jewelers, we have teamed-up with experts who can provide the two most common types of appraisals – Insurance Replacement and Estate.  Insurance Replacement appraisal values are based on the cost to replace your jewelry item in a retail jewelry store.  The Estate appraisal is usually performed for estate tax purposes.  Our appraisal fees are a flat rate of $115 in most cases.  Watches are a bit more at $150 each.  Our appraisers are both well-educated and experienced.

If you haven’t had your jewelry appraised within the last few years it is time to have it appraised.  We will provide you with two copies of your appraisal – one to give to your insurance company and the other for your records.  Having your fine jewelry pieces professionally appraised will allow you to list your jewelry items separately on your insurance policy.






You love your diamond, but you’d like a little more shine. Don’t worry, we’ve got you covered. You can trade in any diamond purchased at Plateau Jewelers, that is in good condition, and receive its full value toward any diamond of greater value. Why not use the opportunity to create a brand new diamond engagement ring while we’re at it?


It’s rather unfortunate, but fine jewelry sometimes wears out. But don’t worry, we can take care of your fine jewelry. We can help restore your fine jewelry to its previous glory. In extreme cases we can even remake the item if necessary.
