    As an unabashed fan of PBS's Antiques Roadshow, I am here to tell you, my fellow millennials, two things: A) Watching this show is the only way to get through 2017 in one piece, and B) It's featured some of the most stunning jewelry your eyes will ever behold. Which makes sense—Antiques Roadshow showcases long-forgotten gems that wouldn't otherwise see the public eye. Here's the best of the best. (By which we mean the most $$$ of the $$$.)

    Yellow Diamond Asscher-Cut Ring

    Yellow Diamond Asscher-Cut Ring

    Appraised: 2006

    Value: $75,000 to $100,000, auction.

    About: Circa 1930, this canary yellow diamond ring was passed down through the owner's family—and is absolutely massive for a yellow Asscher-cut diamond. To quote the appraiser: "It's very hard to get that combination. I've had only one small one in 26 years in the business. So that tells you it's rare." Even cooler, the $75-$100k value was considered "very conservative" back in 2006, so in today's market this thing is likely through the roof.

    Asscher-Cut Diamond Ring

    Appraised: 2007

    Value: $165,000 to $175,000, retail.

    About: This Asscher-cut ring is even more valuable than the one preceding it. For starters, it's a little older—hailing from 1915. The piece comes care of the owner's grandfather's jewelry store, weighs approximately five carats, and is described as a "very, very clean stone." And yes, the appraiser completely nerded out, saying: "That's quite a ring you've got there. I mean, we don't see rings like that."

    Art Deco Emerald and Diamond Ring

    Art Deco Emerald and Diamond Ring

    Appraised: 2008

    Value: $70,000 to $90,000, auction.

    About: This lovely family heirloom is a gorgeous example of Art Deco jewelry, and was made somewhere in the 1920s-30s. The center emerald is a "sugarloaf cut" (intended to maximize the green tone), and has bullet shaped diamond baguettes surrounding it. The piece itself is most likely American (though the stone is from Colombia), and thanks to the Art Deco market peaking, it was given a huge price tag.

     Louis Comfort Tiffany Necklace

    Louis Comfort Tiffany Necklace

    Appraised: 2016

    Value: $70,000 to $90,000 retail.

    About: This circa 1915 necklace was purchased by the owner's husband in the late '70s to early 80s, and he paid just over $3,000. So yeah, it has a pretty hefty mark-up. The piece itself is made from black opals known as "patchwork opals"—and not only was it signed by "Tiffany & Co," it was also signed by man/myth/legend, Louis Comfort Tiffany. 

    Diamond and Pearl Necklace

    Diamond and Pearl Necklace

    Appraised: 2008

    Value: $250,000 retail.

    About: That's right: $250,000. This stunning necklace was passed down through the owner's family, and hails from New York company Phelps & Perry of Maiden Lane. The circa 1905 piece uses Edwardian platinum, and the diamonds are massive—the larger of the two being five carats. At the time it was appraised, the diamond market was pretty volatile, so you can only imagine the estimate in 2017.

    European Cut Diamond & Platinum Ring
    (Image credit: Archives)

    European Cut Diamond & Platinum Ring

    Appraised: 2010

    Value: $60,000 to $80,000, auction.

    About: This massive diamond ring is a whopping 7 carats, and was made in 1925, retailing for $1,000. Interestingly, the eight-prong setting indicates that this ring was intended for a man rather than a woman. It was originally mis-graded before the owner brought it into Antiques Roadshow, where she found out it was worth up to $80k instead of just $20k. 

    Yellow Mine-Cut Diamond Ring

    Yellow Mine-Cut Diamond Ring

    Appraised: 2011

    Value: $70,000 to $90,000, auction.

    About: This lovely 6.5 carat ring was made in 1900, and is what's referred to as an "old mine cut"—meaning there are fewer facets. "It is a really pretty piece, just the center stone as is," explains the appraiser. "And what's nice is, it's not in a yellow mounting or setting that would amplify the yellow. It's actually in a platinum-and-diamond Edwardian setting that complements it beautifully."

    Fancy Intense Yellow Diamond Ring

    Fancy Intense Yellow Diamond Ring

    Appraised: 2011

    Value: $140,000 to $160,000, retail.

    About: This 3.4 carat "fancy" "intense" engagement ring was made in New York City in the roaring '70s, and definitely lives up to its name. The value comes from the gorgeousness of the stone itself, set in a "modern round brilliant cut." We'd like five, please.

    Tiffany & Company Natural Pearl and Diamond Necklace

    Tiffany & Company Natural Pearl and Diamond Necklace

    Appraised: 2012

    Value: $80,000 to $200,000, insurance.

    About: This Tiffany necklace is signed a whopping three times (making it extra special), and was created by one of the company's best and most famous designers Paulding Farnham—who was known for his love of natural pearls. The owner plans to have her daughters wear the necklace at their weddings. 

    Cartier Paris Sapphire and Diamond Earrings

    Cartier Paris Sapphire and Diamond Earrings

    Appraisal: 2013

    Value: $75,000 to $100,000 retail.

    About: These earrings contain six carats of sapphire and six carats of diamonds (casual)—and belonged to the owner's grandmother's sister. In other words, they go way back.

     Louis Comfort Tiffany Necklace
    (Image credit: Archives)

    Louis Comfort Tiffany Necklace

    Appraised: 2014 

    Value: $75,000 to $100,000 auction.

    About: This necklace dates between 1900 and 1908, and is made of black opal, as well as Russian demantoid garnets—the most rare green garnet in existence. Just based on historical significance alone, the piece is worth $8-10k, but the fact that it was made by Tiffany & Co increases the value to $15-20k. The thing is, this piece was *specifically* made by Tiffany himself, which makes it even more valuable.

     Ruby and Diamond Necklace
    (Image credit: Archives)

    Ruby and Diamond Necklace

    Appraised: 2013 

    Value: $80,000 to $100,000, auction.

    About: This piece dates to about 1918, and is what's known as a "transitional" piece in terms of design. It has Art Deco elements (like the baguette diamonds), but also scrolling motifs that give off more of an Edwardian vibe. And while the diamonds are great, it's the three carat Burmese ruby that's the real showstopper—hence the high price tag. 

    Van Cleef & Arpels Necklace
    (Image credit: Archives)

    Van Cleef & Arpels Necklace

    Appraised: 2014

    Value: $125,000, insurance.

    About: This gorgeous necklace was bought at NYC's Van Cleef & Arpels by the owner's father-in-law in 1960. Amazingly, it was actually custom-made based on a sketch that the buyer drew. The diamond weighs 3.91 carats, and is flaked by smaller stones—and believe it or not, it only cost $5,700 at the time.

    Diamond and Sapphire Set
    (Image credit: Archives)

    Diamond and Sapphire Set

    Appraised: 2014 

    Value: $55,000 to $85,000 auction.

    About: This necklace and ring were bought by the owner's grandmother before 1949, and weren't actually part of the same set. The ring is platinum-topped gold with a Burmese sapphire surrounded by diamonds, and dates from 1910-1915. It's worth between $25-35k. Meanwhile, the necklace was made to go with the ring in the 1920s, and is worth an additional $30-50k. The pear-shaped drop alone has two and a half carats of diamonds, while the tassel is decked out in sapphires.  

    Diamond Engagement Ring

    Diamond Engagement Ring

    Appraised: 2014 

    Value: $55,000 to $65,000, retail.

    About: This lovely engagement ring (from the owner's husband) is hilariously referred to as a "fat pear" in terms of shape—and weighs five carats. The ring is Art Deco in aesthetic, and was made in America by little known designers K and F and Company.
