Here at Plateau Jewelers, we have experts who can provide appraisals of all kinds including, but not limited to; Fine jewelry, diamonds, gemstones, sterling flatware, watches, and more. Our appraisers are both well-educated and experienced, and our accredited gemologist can properly identify and grade diamonds and colored stones.

If you haven’t had your jewelry appraised we highly recommend you have it documented in detail. Having your pieces professionally appraised will allow you to have a separate insurance covering the full value of your fine jewelry. Our appraisals can also be used for situations such as; estate tax evaluation, value comparison, casualty loss, dissolution of marriage (divorce), collateral and barter purposes.


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.


It’s sad, but jewelry sometimes wears out. If that happens to your jewelry we can help restore it to its previous glory. In extreme cases we can even remake the item if necessary.
