On This Free Masterclass, You'll Discover:


-Why the number on an appraisal and the number you'll get paid are almost never the same thing

And which one matters depending on what you're doing with your jewelry.


-How to know what your gold jewelry is really worth in today’s historic market

The simple calculation every jewelry owner should know before accepting an offer.


-Why some diamonds are quietly losing value every quarter while others are climbing

Most owners have no idea which one they're sitting on.


-The one thing a diamond certificate doesn't tell you

Two stones with the same grading report can be worth completely different amounts.


-Why "shop around and compare offers" isn't the same as knowing what you own

The difference between the two could mean thousands of dollars.


-The exact red flags that have shown up in documented fraud cases this year

So you know what to check before you buy or sell.


-Why the smartest engagement ring buyer isn't the one who spends the most

It's the one who knows exactly what they're paying for.


And much, much more!

MEET YOUR HOST

I'm Tammy Trésor AKA The Jewel Princess

Tammy Tresor, Gemologist

I'm a fourth-generation jeweler.

Jewelry runs on both sides of my family.

I'm also a GIA graduate gemologist.

I train at the world headquarters of the Gemological Institute of America.

I studied under a former Tiffany & Co. master craftsman.

I've worked in every corner of this industry.

Retail. Wholesale. Appraising. Buying. Sourcing. Design.

I've sourced six- and seven-figure diamonds and colored gemstones from around the world.

I've worked with clients ranging from everyday families to A-list celebrities and NFL players.

I'm also a court-qualified expert witness.

I've been called to testify in legal matters involving jewelry, gemstones, and valuation.

Here's a story that changed how I think about this industry.

A client came to me with a six-figure gemstone.

It had been sold to them as natural.

My evaluation told a different story... It was lab-created.

I help this client uncover the misrepresentation and recover their money.

* Case example for illustrative purposes. Outcomes are specific to that situation and are not guaranteed.

This is not a rare story anymore, and I'll show you why during this masterclass.

I built my career on one belief...

You shouldn't need a gemology degree to avoid getting taken advantage of.

You just need the right person in your corner before you buy or sell.

This Thursday at 7 pm Eastern, I'm walking you through what that looks like.

This Free Masterclass Is

BUILT For:

Anyone currently shopping for an engagement ring or fine diamond jewelry

Anyone who owns jewelry they're considering selling

Buyers comparing diamonds that look similar on paper but are priced completely differently

Sellers who have received an offer that felt lower than expected and want to know if that's normal

Anyone who wants an independent, unbiased opinion before a major jewelry decision

This Free Masterclass Is

NOT For:

Anyone only looking for the lowest possible price with no interest in why

Anyone who believes all jewelers, appraisers, and diamond buyers are essentially the same

Anyone comfortable making a major jewelry decision based on a single online price comparison

What's Happening In The Jewelry Market Right Now


Gold hit an all-time high of $5,589.38 per ounce on January 28, 2026.


This broke a record that had stood since 1980, adjusted for inflation, for 46 years.


Major banks now forecast gold could reach $5,700 to $6,000 per ounce by the end of this year.


At the same time, something very different is happening with lab-grown diamonds.


Wholesale prices for lab-grown stones have fallen as much as 93% since 2020.


Industry sources describe this as a structural shift, not a temporary dip.


Meanwhile, multiple jewelers have been criminally charged in 2025 and 2026.


The charges involve swapping natural diamonds for lab-grown stones and misrepresenting them to customers.


*Sources: World Gold Council, Goldman Sachs, Société Générale market forecasts, and public court filings, 2025-2026. Individual jewelry values vary by piece, condition, and market at the time of appraisal.


Two different markets are moving in two completely different directions at the same time.

Frequently Asked Questions

Is this masterclass really free?

Yes. This is a live training, not a disguised pitch. You'll walk away with usable insight whether or not you go any further with Tammy. At the end, she'll share how to go deeper if it's a fit. There's no obligation to buy anything.


Do I need to already know anything about diamonds or jewelry?

No. This is built to be understood by someone with zero background in the industry.


I haven't decided if I'm buying or selling yet. Is this still for me?

Yes. This masterclass covers both sides so it's useful whether you're leaning toward buying, selling, or still deciding.


What if I can't attend live?

Register anyway but a replay isn't guaranteed. Live attendees get real-time Q&A access so attending live is strongly recommended.


Will I be pressured to buy something on this masterclass?

No. This is an educational training first. If it makes sense to go further afterward, Tammy will explain how and it's entirely optional.
