Inherited Jewelry: Is It Really Worth What the Old Appraisal Says?

One of the most common misunderstandings about inherited jewelry is assuming that an old appraisal represents what the jewelry can be sold for today.

For example, you might find an insurance appraisal from several years ago stating that a diamond ring was valued at $25,000.

Does that mean you can sell it for $25,000?

Not necessarily.

Jewelry can have different values depending on the purpose of the appraisal, the market being researched, and the circumstances of the transaction.

Replacement Value for Scheduling Insurance Coverage

This value is developed through market research at the retail market level. It estimates how much it would cost to replace your jewelry with a comparable piece of similar quality and characteristics in the event of loss or damage, as of the appraisal date.

For example, if your diamond ring is lost or stolen, the insurance replacement value estimates the cost of obtaining a comparable ring through the appropriate retail market.

This value is commonly used to help establish insurance coverage, but it does not represent what you could expect to receive if you sold the ring.

Fair Market Value (FMV)

Fair Market Value estimates the price at which jewelry would change hands between a willing buyer and a willing seller, neither being under pressure to transact and both having reasonable knowledge of the relevant facts.

For inherited and estate jewelry, this often involves researching comparable transactions in the secondary jewelry market, where previously owned jewelry is bought and sold.

Fair Market Value is commonly used for estate administration, estate tax reporting, inheritance distribution, and certain other legal or tax purposes.

Unlike insurance replacement value, which focuses on replacing jewelry at the retail level, Fair Market Value addresses an exchange under specific market conditions and valuation assumptions.

Resale or Marketable Cash Value (MCV)

Marketable Cash Value focuses on the amount of cash that could reasonably be realized from selling jewelry in a specified market, under defined selling conditions and within an anticipated exposure period.

Like Fair Market Value, it may rely on research in the secondary jewelry market. However, it focuses more directly on the practical circumstances of selling the jewelry.

For example, if you inherited a diamond ring and wanted to sell it, the amount you could reasonably expect to receive would depend on its quality, condition, current market demand, the buyers available, and the selling method selected.

Selling directly to a professional jewelry buyer may produce a different result from selling through an auction, consignment arrangement, or specialized jewelry broker.

What Is the Difference Between Fair Market Value and Marketable Cash Value?

Both values may be supported by similar secondary-market research, but they answer different questions.

Fair Market Value asks what the jewelry would exchange for between a willing buyer and seller under the applicable valuation definition.

Marketable Cash Value focuses on the cash amount that could reasonably be realized through a specified selling market and under defined transaction conditions.

Depending on the circumstances, these values may be similar or different. Fair Market Value is not automatically higher than Marketable Cash Value.

Why Your $25,000 Insurance Appraisal May Not Mean a $25,000 Selling Price

An insurance appraisal may be considerably higher than the amount a professional jewelry buyer is prepared to offer.

That does not automatically mean the original appraisal was incorrect or that the buyer's offer is unfair.

The insurance appraisal estimates the cost of replacing the jewelry in the appropriate retail market, while a resale offer reflects what a buyer is willing to pay in the current market, taking into account demand, resale opportunities, expenses, and business risks.

The appraisal date also matters. Diamond prices, consumer preferences, and market conditions can change over time.

Practical tip: If you are considering selling inherited jewelry, explain your goal before commissioning an appraisal. Not every piece requires a formal written appraisal, particularly if its value is relatively modest. For important diamonds, antique jewelry, signed designer pieces, or valuable collections, professional evaluation and market research can help you understand your options before accepting an offer.

It’s not every day you get to meet someone with such a remarkable connection to gemological history! 💎✨

One of the highlights of the ASA International Conference in Fort Worth was meeting Mark Cullinan, CEO of Cullinan Diamonds and great-grandson of Sir Thomas Cullinan, founder of the mine where the legendary Cullinan Diamond was discovered in South Africa in 1905.

Weighing an extraordinary 3,106 carats, it remains the largest gem-quality rough diamond ever discovered!

During his presentation, Mark shared fascinating stories about the diamond and even showed us a replica of the original Cullinan rough diamond, giving us a sense of its incredible size!

A fun piece of history: While a decoy reportedly traveled under heavy security, the real diamond was sent to England by registered mail. It was later cut into nine major stones, including Cullinan I and II, now part of the British Crown Jewels. 👑

What a pleasure meeting someone whose family name is part of gemological history!

We recently had the pleasure of visiting the Heritage Auctions world headquarters in Dallas alongside our fellow industry professionals.

At La Jolla Gem Appraisal, understanding the secondary market is an essential part of our work. Beyond providing independent jewelry appraisals, we assist clients with the sale of fine jewelry through our established network of experienced buyers.

Opportunities like this allow us to gain valuable insights into the auction market, collector demand, and how important jewelry is evaluated and traded. Staying connected to the market helps us provide our clients with well-supported valuations and informed guidance when selling their jewelry.

A sincere thank you to the Heritage Auctions team for the warm hospitality, insightful discussions, and the opportunity to exchange knowledge with fellow industry professionals! 💎

These two remarkable Tiffany & Co. brooches were among a collection we recently helped a client successfully sell, including Jean Schlumberger’s iconic Bird on a Rock and this extraordinary flamingo brooch.

Inherited jewelry can hold value in ways that aren’t always obvious. Maker, rarity, gemstones, craftsmanship, condition and collector demand can all make a significant difference.

What makes our service different?

We can first independently evaluate and value your jewelry, providing a market evidence-based appraisal report so you understand exactly what you have and its value in the appropriate market.

If you decide to sell, we also have an established network of knowledgeable, serious buyers for fine jewelry, important diamonds and signed pieces.

💎 Inherited jewelry? Before you sell it, insure it, redesign it, or divide it among family members, first understand what you have.

Jewelry passed down through a family can carry significant sentimental value, but figuring out what to do with it isn’t always simple.

A few things to consider before making any decisions:

1️⃣ Don’t alter it yet.
Before cleaning, repairing, resizing, or redesigning a piece, have it properly examined. Hallmarks, signatures, construction and original condition can all provide useful information.

2️⃣ Keep the paperwork.
Old appraisals, receipts, laboratory reports, boxes, photographs and family records may provide important clues about the jewelry’s history and identification.

3️⃣ Find out what you actually have.
Diamonds, colored gemstones, precious metals, maker’s marks, condition and workmanship may all need to be evaluated.

4️⃣ Know which value you need.
Insurance replacement value, estate value and resale value are not necessarily the same. The purpose of the appraisal determines the appropriate market and definition of value.

5️⃣ If you’re dividing jewelry among heirs, remember that value isn’t only monetary.
An independent appraisal can help establish an objective financial basis, while your family decides how sentimental and historical importance should factor into the division.

6️⃣ If you may sell, don’t use an insurance appraisal as your expected selling price.
The secondary market can be very different from the retail market used for insurance replacement.

And perhaps most importantly: you don’t have to decide right away.

Sometimes the best first step is simply learning what you inherited. From there, you can make an informed decision about what to keep, insure, divide, redesign or sell.

This Saturday, I’ll be presenting at the NAJA Mid-Year Conference on a topic that has sparked plenty of conversation: AI for Jewelry Appraisers.

You don’t need AI to be a competent jewelry appraiser. But could it amplify your efficiency, and your capabilities? Where can AI genuinely assist us, and where does human expertise remain irreplaceable?

That’s the conversation I’m looking forward to having on this Saturday!

And thank you, National Jeweler, for featuring the conference and speaker lineup https://nationaljeweler.com/articles/15215-naja-announces-lineup-for-2026-fall-virtual-conference

We’re pleased to share that La Jolla Gem Appraisal, operating under GemIntellect LLC, has successfully renewed its SAM.gov registration as an active federal vendor.

Maintaining this registration allows us to remain available for federal contracting opportunities where independent expertise in jewelry, diamonds, gemstones, and valuation may be needed.

Alongside our work with private clients, attorneys, fiduciaries, and other professionals, we are grateful for the opportunity to make our specialized knowledge available for government-related assignments as well.

We remain committed to the same principles that guide all of our work: independence, objectivity, professional standards, and careful documentation.

04/01/2026

With the dramatic rise in gold prices over the past few years, the value of many estate jewelry pieces has increased significantly. For example, a 7.8-gram 18K yellow gold ring that might have been worth around $350 just two years ago could be worth around $800 today.
That change comes purely from the metal value, not from diamonds, craftsmanship, or collectibility.
Now imagine this effect across an entire estate collection.
This is one reason estate jewelry should be professionally reviewed before making decisions about insurance, division among heirs, or selling.
Sometimes the value of a collection today is very different from what the family expects.
If you need guidance with estate jewelry, schedule an appointment with our Master Gemologist Appraiser to ensure the process is handled accurately and with care.
