Most customers discover that Geoff does appraisals only after years of visiting. That ends here. A dual-certified GIA gemologist with 30 years of appraisal experience is a rare asset — and every report he produces is accepted by insurers, attorneys, and courts.
At Cranstoun Court, every appraisal is performed personally by Geoff Woerner. He holds both the GIA Graduate Gemologist designation — the highest credential awarded by the Gemological Institute of America — and the Certified Gemologist designation from a second independent accreditation body. Most local jewelers hold neither. Holding both simultaneously places Geoff among a rare tier of qualified appraisers anywhere in Arizona.
The highest gemological designation in the world, awarded by the Gemological Institute of America. Requires completion of six to seven rigorous courses plus a three-hour final examination — the credential required for certified insurance appraisals. Geoff has held it for over 30 years.
A second independent professional designation from a parallel accreditation body. Holding both the GG and CG simultaneously is an exceptionally rare combination among independent jewelers in Arizona — and a meaningful distinction when your piece needs to stand up to scrutiny.
Professional certified appraisals since approximately 1996 — three decades of insurance, estate, legal, and consignment valuations across thousands of individual pieces. That real-world depth is what separates a credential from genuine expertise no algorithm can replicate.
Every appraisal Geoff performs is conducted with the same care and precision — whether it is a single ring or a full estate collection. Nothing is delegated. Nothing is rushed.
Geoff personally handles every piece using professional gemological instruments — loupe, microscope, and testing equipment. Nothing is delegated to an assistant. You receive his full attention and 40 years of trained eyes.
Current replacement costs, comparable sales, and live market data are researched for every item. Four decades of context informs what raw data alone cannot. Your piece is valued in the real world — not against an outdated table.
A fully signed professional report: item description, measurements, stone grading, metal analysis, and certified value — accepted by insurance providers, attorneys, and courts. You receive a document that carries real weight.
Single pieces are often completed the same day you walk in. Estate collections and larger appointments are accommodated with advance scheduling. Call ahead and Geoff will work around your schedule.
Appraisals are not one-size-fits-all. The number that matters for insurance is very different from the number that matters in a courtroom or estate settlement. Geoff will walk you through exactly which type you need — and why.
The most commonly needed appraisal. Documents the retail replacement cost of your piece — required by insurers to issue proper coverage. Without it, a claim may pay only a fraction of true value. If you own fine jewelry and do not have a current appraisal on file, this is where to start.
Evaluate what you have received before making any decisions. When a loved one's collection arrives, it deserves proper expert attention — not a quick glance and a guess. Geoff examines every piece individually, with no batch shortcuts and no assumptions. Know what you have before you give anything away or sell.
What a knowledgeable buyer would pay for your piece in an open, unrestricted market. Used for charitable donation tax filings, divorce settlements, estate tax purposes, and legal proceedings. This is the number courts and accountants rely on — it requires the same credentials and rigor as any other appraisal.
Know your piece's true value before selling or consigning it anywhere. Many customers are genuinely surprised by what they have — and how much they would have left on the table. Walk into any sale from a position of knowledge, not assumption. One appraisal often pays for itself many times over.
Most people have no idea which type of appraisal they actually have — or whether the number on their document protects them in the way they assume it does. The difference between insurance replacement value and fair market value can be tens of thousands of dollars.
An insurance appraisal reflects what it would cost to replace your piece at retail today. Fair market value reflects what a buyer would realistically pay. These are two completely different calculations — and confusing them can cost you significantly.
Geoff takes the time to explain which type of appraisal you actually need and why. There is no pressure, and the first look is always free. Come in and have a conversation.
"The difference between these two numbers can be significant — and most people don't know which one they have. That's exactly the kind of conversation we have every day at Cranstoun Court."
Most appraisers rely on assistants, outdated databases, or rushed assessments. At Cranstoun Court, Geoff Woerner — the owner and a dual-certified gemologist with over 40 years of experience — handles every piece himself, start to finish.
His reputation in this community is built entirely on trust. Families have been returning for decades — and the reason they give is always the same: they know Geoff will be straight with them.
Do I need an appointment for an appraisal?
Single pieces often don't require an appointment — walk in Monday through Friday between 10 AM and 5 PM and Geoff will make time for you. For larger estate collections, calling ahead to schedule is recommended so Geoff can give your collection the full attention it deserves without interruption.
What does a certified appraisal include?
A complete professionally written and signed report including: item description, all measurements, stone grading and identification, metal analysis, and a certified value conclusion. The report is accepted by insurance providers, attorneys, estate executors, and courts. This is a real document — not a slip of paper.
How long does an appraisal take?
Single pieces are often completed the same day you bring them in. Estate collections and larger groups require more time and are accommodated by appointment. Call ahead and Geoff will give you a realistic timeframe based on what you have.
What types of jewelry can be appraised?
All fine jewelry — diamond rings, sapphires, emeralds, rubies, and other gemstones; gold and platinum pieces; estate and antique jewelry; inherited collections; watches; and any piece where you need a documented professional value. If you are unsure, bring it in and Geoff will take a look.
Is the first look really free?
Yes. If you want to bring a piece in for an initial conversation before committing to a formal appraisal, that first look carries no charge and no obligation. Geoff will tell you honestly whether a full appraisal makes sense for your situation. That is simply how Cranstoun Court operates.
I inherited jewelry and don't know if it's valuable. Where do I start?
Come in and bring the collection. Many people are surprised by what they have inherited — and equally surprised by what they were about to give away or sell for far less than it was worth. Geoff will evaluate each piece honestly and walk you through what you have before you make any decisions.
No pressure. No obligation. The first look is always free.
Walk in and talk to Geoff — 30 years of certified appraisal experience behind every answer.
