CashingDiamonds Third-Generation Expertise in Fine Jewelry, Estate Jewelry & Luxury Brands
My name is Alex Goldberg, and I represent the third generation of a family deeply rooted in the fine jewelry business. Our journey began in the late 19th century, when my grandfather David Goldberg established our family’s jewelry trade in Europe. From my grandfather, the knowledge was passed to my uncle, then to his son, and ultimately to me.This uninterrupted chain of experience, spanning well over a century, is what gives Cashing Diamonds its greatest strength: the ability to recognize true value, even when others overlook it.
Professional Buyer of Luxury & Estate Jewelry
At CashingDiamonds, we specialize in buying and evaluating:
- Tiffany & Co.
- Van Cleef & Arpels
- Cartier
- Bulgari
- Harry Winston
-
Graff
We focus on estate jewelry, signed vintage pieces, rare gemstones, important diamonds, sapphire and emerald rings, and unique historical designs. These are not everyday items — and they require trained eyes, deep market knowledge, and historical awareness.
A Real Case That Shows Why Experience Matters
One day, a client contacted me after his mother passed away. He needed a professional appraisal for estate purposes and scheduled an appointment at our office. He brought several beautiful pieces of jewelry, but one ring immediately caught my attention.
It was a sapphire ring, elegant and understated — but something about it felt special.
After a closer look, I told him:
“I need to go deeper. This ring may be very important.”
The craftsmanship, the sapphire quality, and the design language strongly suggested a 1950s era piece. I conducted in-depth research, cross-checked archival references, and confirmed that the ring was an original 1950s Van Cleef & Arpels sapphire ring — a rare and highly collectible piece.
The Result: From Unknown Ring to Six-Figure Value
After proper authentication and valuation, we appraised the ring at approximately $140,000.
Instead of rushing a sale, I advised the client on the best possible route to maximize value — including auction placement.
The final result:
- Sold at auction for approximately $147,000
- The client received a clear, honest valuation
-
He avoided underselling a once-in-a-lifetime heirloom
This outcome happened for one reason only: he came to the right professional.
Why People Lose Money Without Proper Evaluation
We see this situation often:
- Inherited jewelry after a family member passes away
- Jewelry divided during a divorce
- Long-owned pieces sitting in safes or drawers for decades
-
Vintage or signed jewelry mistaken as “ordinary”
Many people simply don’t know what they have — and without expert evaluation, they risk selling rare assets for a fraction of their true value.
