Services
We offer a variety of services for jewelry including custom jewelry design and creation, repair, appraisal documents and much more. All jewelry, especially rings, should be checked and cleaned on a regular basis, we recommend two to three times a year. This service is free of charge and available any time, even if we did not make or sell the piece! We can often catch repairs needed before they become problems and get them fixed and back in (or on) your hands quickly.
Custom Jewelry Design
We create jewelry in many different ways. We hand carve waxes then cast and finish them, hand-fabricate jewelry out of wire and stock or create them through computer-generated jewelry design. Sit with one of our talented design team members and then watch your ideas come to life! Our skilled goldsmiths can create the perfect one-of-a-kind piece just for you. Please check out our Custom Jewelry page to see examples of some of our beautiful custom pieces we have made.

Goldsmith Services and Jewelry Repair
The Gem Gallery has three full-time goldsmiths, Philip Devitt, Chris Tullar, and Julie Fournier. We can do everything from simple jewelry repair and ring sizing to making custom heirloom designs in platinum, palladium, gold and silver. Having in-house goldsmiths means your jewelry does not have to leave the premises to be repaired and you can be assured it is safe in our expert hands.
Unlike other businesses, our in-house team can conduct jewelry repairs and alterations on the premises. If you have questions regarding a piece of jewelry, please bring it in and our staff will be happy to help you in any way!

Other jewelry care tips:
-Put your jewelry on last when getting ready and take it off first before bed. This habit keeps your jewelry away from things like make-up, hair-spray, perfume, and lotion as you’re applying them.
-You should remove your jewelry when: • Lifting weights at the gym • Rock climbing, mountain biking, gardening, etc. • Soaking in hot tubs/springs
Please note that wear and tear is normal and over time your jewelry will need some maintenance. These are a few of the common repairs / services that are often needed to make sure your jewelry lasts a lifetime.
• A white gold appearing to be yellow - Your ring may need
rhodium plating
• The prongs wear down or snag on clothing — may need re-tipping
• The metal shows scratches and abrasions - The piece can
usually be refinished to look new
• The base (shank) of the ring is thin or breaking - It may need to
be re shanked
• Stones are loose or lost - Stones can often be tightened or
replaced as needed
• The ring is too small or big - Rings can usually be resized, let
us take a look

Appraisal Services
The Gem Gallery offers appraisals for both our in-house jewelry as well as pieces from your personal collection. Our appraisals provide formal insurance replacement documentation, detailing the full replacement value of your jewelry. Each appraisal includes a formal description of the piece, its replacement cost, as well as professional photography.
Valuation
Appraisal valuation is for insurance replacement value for the current condition of the item at the current market pricing. It is how much we would charge to make or source a new replacement if the item was damaged or lost. It is not an offer to purchase the item, nor an indication of what the item can be sold for.
If you are interested in selling your jewelry to us, please refer instead to our We Buy Gold section below.
What’s Included
Pricing
Estate Appraisals (Groups of 4+ pieces)
How to Get Started
In the case of appraising larger diamonds or gemstones, we recommend having the stone graded by G.I.A. diamond grading company, a service we also provide under our Diamond Grading Services section below.
Each appraisal is a thorough, formal process. We will:
- Clean and carefully inspect each piece
- Evaluate and record gemstone types, sizes, qualities, and weights
- Provide a detailed written document with replacement values and images
Due to the detailed nature of our evaluations, we typically hold your jewelry for about two weeks while the assessment is completed. Your jewelry is then available for pickup, and the final appraisal documents are ready within 4–6 weeks, which you can pick up in person, or receive by mail or email.
Pricing
Appraisal costs vary depending on the complexity of the piece:
- Most pieces are $400 to appraise
- Very simple items like a loose gemstone, stud earrings, or a solitaire ring or pendant start at $250
- Highly complicated pieces will be assessed on a case-by-case basis, but could be:
- Large pieces with many gemstones
- Vintage or designer pieces with historical research required
- Rare gemstones, processes or techniques
- Reappraising an item previously appraised by Gem Gallery may be able to be done at a reduced rate to update current condition and market prices.
Because of the detailed process, we can appraise up to four items at a time. Each piece will be priced individually.
Estate Appraisals (Groups of 4+ pieces)
We offer light documentation for a group of more than four pieces priced as an estate. This service starts at $600, and increases based on complexity and number of pieces. Items will be listed on a single document with approximate values and brief descriptions. Not recommended for items over $5000.
How to Get Started
No appointment is needed. You’re welcome to bring your jewelry in at any time during business hours. Any of our sales staff can assist you with check-in, review pricing, and collect any existing certificates or documentation you may have for your pieces.
Insurance
Every insurance company has different requirements on when an appraisal is needed and how long they can be used before requiring an update. Often only items over $5000 require an appraisal. Many insurance companies require an updated appraisal every 5-10 years. We recommend asking your insurance company what they require before bringing items to us to appraise.
Hourly Services for Identification - No Formal Documentation
Other ServicesWe offer identification services for jewelry and gemstones at an hourly rate. This service does not provide any formal documentation or valuation, but can be helpful to know what you have and identify pieces needing more thorough appraising.
- In-person appointments with you present:
- 30 minutes: 1-2 pieces depending on complexity - $75
- 60 minutes: 2-3 pieces depending on complexity - $150
- For more than 3 pieces, you will need to leave your jewelry with us, and we will evaluate it in a timely manner. Once the evaluation is complete we will contact you to pick up your jewelry.
- Our staff will let you know all pricing in advance before we begin the evaluation.

We Buy Gold
Have jewelry you no longer wear? We’re happy to purchase it from you. Gem Gallery buys all forms of gold jewelry, evaluating each piece based on its purity, weight, and current market value. Our experienced team of jewelers and goldsmiths ensures every evaluation is accurate and transparent.
Once we assess your items, we’ll make you an offer on the spot. You’ll receive a check immediately, or we can provide 15% more in store credit toward any in-store or custom purchase.
If you’re interested in creating something new, your gold can often be repurposed toward your next piece either as materials or as credit toward a custom design.
We do not purchase:
- Dental gold with teeth attached
- Silver plated jewelry or objects
- Plated gold jewelry
- Non-precious metals
Quick tip: To check whether your piece might be gold or silver, hold a magnet near it. If it sticks, it’s likely not a precious metal. Some fine jewelry may have small magnetic parts like clasps, so test the entire piece for accuracy.
Appointments are recommended so our team can give your jewelry the attention it deserves.

Pearl Restringing
Your grandmother’s pearls are more than just jewelry. They’re a family heirloom, a symbol of timeless elegance, and a reminder of cherished memories.
Over time, the threads that hold pearl necklaces together fray and stretch. We recommend restringing your necklace every two years, if you wear your necklace regularly. If you don’t know when your pearl necklace was last restrung or how often it’s been worn, come talk with a jeweler!
