Overview: Main Themes

In this episode, Rachel Uchitel sits down with Chris D. Gatto, a veteran of the diamond and jewelry industry, to uncover the truth behind diamonds: their value, the mystique, the misconceptions, and the business mechanics that drive the market. From the hidden world of 47th Street to global luxury trends and the impact of lab-grown stones, Chris shares insider knowledge and debunks common myths, making the intricacies of diamonds accessible to anyone curious or skeptical about what sparkles on their finger.

Guest Background & Industry Entry

[02:35 – 04:57]

• Chris grew up in Manhattan and was exposed to the diamond industry through family.
• Inspired by the mysterious jargon and aesthetics, he studied to become a gemologist at 17 at the Gemological Institute of America.
• Apprenticed as a diamond cutter in New York's famed Diamond District (47th Street), eventually becoming a partner in a prestigious company.

"The industry, as people on the inside know, has its own lexicon, its own vernacular that sounded all really mysterious and James Bond like to me."
— Chris D. Gatto [03:20]

The Path to Business & Secondary Market Revolution

[06:41 – 09:05]

• After cutting, Chris noticed the lack of fair resale options for jewelry and launched Circa in 2001, which became the largest public buyer of diamonds/jewelry.
• Circa provided dignified, transparent selling options (vs. pawn shops or intimidating auction houses) and shifted stigmas around selling jewelry.

"People aren't being treated correctly when they sell a piece of jewelry or a diamond… It was highly stigmatized then—people selling jewelry, it was like, 'Oh, you need the money.'"
— Chris D. Gatto [07:48]

Understanding Value: The Secondary Market

[09:05 – 13:01]

• Value retention for diamonds depends on item type, purchase timing, and whether it’s a commodity (like a certified diamond) or a branded piece.
• Certain luxury jewelry (Cartier, Tiffany, etc.) and bigger stones hold value best, often outperforming other luxury items like cars.

“If you're buying a great item… it's a store of value. Is it an investment? You shouldn't be buying it as an investment, but it's a store of value.”
— Chris D. Gatto [10:48]

Brand, Vintage, and Emotional Value

[13:01 – 16:57]

• Signed, vintage jewelry holds value and is highly sought after; craftsmanship is rarely matched in modern pieces.
• The emotional connection to jewelry (new vs. pre-owned) remains a potent force.

“I keep saying jewelry is… really personal. If you don’t mind that your engagement ring isn’t branded… go with a trusted jeweler.”
— Chris D. Gatto [17:16]

What’s Misunderstood About Diamonds

[18:27 – 22:01]

• The most misunderstood aspect? The cut, which governs brilliance more than color or clarity.

“The most important thing people don’t realize is the cut of the diamond… It should say excellent polish, excellent symmetry, etc. Right. So cut is really important, and that's something that often gets lost in the conversation.”
— Chris D. Gatto [18:40]

• Chris breaks down clarity (Flawless, VVS, VS, SI, I) and color grades (D-Z, then “fancy” colors), and explains market region preferences.

Sweet Spot: D-H color, VS clarity and better are most commercially viable.

Diamond Shapes and Trends

[22:01 – 23:09]

• Classic shapes: round, emerald, marquise, pear, oval.
• Rounds always trade at a premium, but fancy shapes (especially large pears and ovals) are currently in demand; trends cycle over decades.

Lab-Grown vs. Natural Diamonds: Myths & Reality

[28:41 – 34:02]

• Lab-grown are real diamonds chemically, but are “a tech product” — limitless supply drives prices down hard.
• Lab-grown diamonds are not more ESG-friendly than mined; diamond mining now is highly regulated and often supports local economies.
• Natural stones are inherently scarce (centuries to mine, limited supply), offering real resale value and intrinsic worth.

“Lab-grown is a tech product by definition… over time it becomes cheaper and cheaper to produce… So what's happened? Lab-grown prices have collapsed.”
— Chris D. Gatto [30:50]

• Lab-grown = “costume jewelry” in resale value; big brands like Swarovski may capitalize.
• The human ritual and signaling value of a natural diamond are irreplaceable for many.

The Journey: From Earth to Jewelry

[33:54 – 37:40]

• Major sources: Africa, Canada, Russia, Brazil, Australia.
• Finding: Geologists look for kimberlite pipes or alluvial deposits; requires substantial investment and luck.
• In the rough, diamonds rarely look like gems; each mine has its own profile for size, color, and quality of output.

“To wind up with… a 20 carat emerald cut, that’s coming from a stone that’s minimum 50, 60 carat in the rough… Size matters with diamonds.”
— Chris D. Gatto [36:31]

Colored Diamonds & Other Gemstones

[37:40 – 38:47]

• Fancy colored diamonds (yellow, pink, blue, red, green, orange) are extraordinarily rare, especially vivid hues.
• Colored diamonds are still diamonds (carbon structure), just with trace elements.
• Rubies, sapphires, emeralds are different minerals altogether.

Financing the Diamond Industry

[39:00 – 40:36]

• Banks retreated post-2008 crisis; Chris’s finance group supplies short-term, asset-backed lending to major diamond players.
• Inventory lending is safe due to the industry’s stability and global resale markets.

Luxury Market Dynamics & Generational Trends

[42:01 – 45:19]

• Young buyers (Gen Z) are more influential than ever; LVMH’s sales are 55% Gen Z.
• Social media amplifies aspiration; luxury purchases (jewelry, bags) remain highly desirable among new generations.

“For every woman at a certain stage saying, 'I'm done with luxury,' there's a horde of young ladies that would love to have a big diamond, would love to have an Hermes bag…”
— Chris D. Gatto [42:42]

Personal Values & The Essence of Luxury

[45:19 – 46:24]

• For Chris, true luxury is “peace and time with family and friends,” not simply objects.

“To me, peace of mind is the ultimate luxury.”
— Chris D. Gatto [45:28]

Industry Outlook & The Future

[49:21 – 53:44]

• Chris warns that the industry “hurt itself by rushing for profit” in promoting lab-grown stones as equal, misleading many consumers.
• Secondary market for natural diamonds remains strong.
• Scarcity: If no new diamond mines are found, natural supplies could run out by 2050.

“There will become a point where there’ll be no more natural diamonds and you’re only going to have what’s being recycled… unless we find others.”
— Chris D. Gatto [53:16]

Lab-Grown Pricing Pitfalls

[54:49 – 56:10]

• Lab-grown prices have collapsed due to overproduction. Chris cautions against high prices for lab-grown (“tech product can be made in unlimited supply”), noting many buyers have already lost significant resale value.

Advice for Buyers & The Modern Diamond District

[57:19 – 58:27]

• Personal buying experiences are best; online is viable, but nothing replaces face-to-face.
• 47th Street has changed, no longer the tight-knit community of old; the real diamond industry now operates “upstairs”—in the buildings, not storefronts.

Memorable Stories & Final Reflections

[47:28 – 49:14]

• Chris’s favorite stone: a 50+ carat cushion-cut diamond purchased in Geneva after a dramatic negotiation, shared sentimentally with his daughter.

Fundamental Takeaways & Closing Insights

[61:11 – 62:54]

• Diamond pricing is highly stratified; not all prices move together. High-value stones remain solid, while lower-mass market (lab-grown competition) has suffered price drops.
• The episode closes on dispelling myths, advocating for an informed, personal, and value-aware approach to buying jewelry—natural diamonds in particular.

Notable Quotes

• On diamonds as a store of value:
  "Most luxury items that people buy hold value, but they're okay with it. Diamonds and jewelry, for some reason, people seem to have a higher expectation…" [10:32]
• On lab-grown vs. natural:
  “Lab-grown is a tech product… What’s the kind of… immediate thing you know about a tech product is that over time, it becomes cheaper and cheaper to produce.” [30:53]
• On the next generation:
  “For every Bethenny Frankel… there’s a horde of young ladies that would love to have a big diamond.” [42:42]
