Discovery in 2009
A group of American gemologists were invited down to visit the Belmont Mine in Minas Gerais, Brazil. Belmont is not only the largest green emerald mine in Brazil, but it also produces the highest quality. After several days touring the shaft and cutting facilities, the group of gemologists had the opportunity to visit a nearby local mine that had come across and unusual gem.

Mining begins
After descending into a 1,200 ft deep, hand dug shaft, a pocket of vibrant natural gemstones was discovered after many years of hard labor. These miners were hunting for green emeralds when this incredible greenish/yellowish vein unexpectedly appeared. Emeryl is Beryl, which is the same species as green emerald, hence the nickname "Yellow Emerald." The trace of ferrous iron in this mountain causes this natural golden yellow color to appear instead of green.

Cruise ship debut
On December 1, 2010, Allure of the Seas took it's maiden voyage out of Miami, Florida. This was the pride and Joy of Royal Caribbean as it was the largest cruise ship ever built with amenities no one has ever seen before. The management could have chosen any gemstone to feature on this voyage in including diamond. However, once they heard about this new and electrifying gemstone, Emeryl, they decided to feature this gem to their 6,000 passengers and 2,200 crew members. Passengers, crew, and management loved this unique gemstone, and it has been featured on every Royal Caribbean ship in their fleet since this initial voyage.

Largest Emeryl sets sail
The largest Emeryl gemstone ever discovered just made a massive splash in the Caribbean. Its maiden voyage was on the ms Noordam on April 7, 2011. The oval gemstone weighed 147 carats, cut in a modified oval shape. It took six months to precisely place over 100 facets by hand. Pictured is Captain John Scott and several officers on the ships' bridge. Passengers were allowed to hold the gemstone and take pictures. The stone is currently insured for $1,000,000 and was only allowed out of its glass showcase while at sea. The nickname given to it on the ship was: "The Golden Egg." This gemstone will be on tour throughout the Holland America fleet in 2011, and then offered to the Smithsonian Institute in Washington D.C. – Patrick Coughlin, Coughlin Jewelers, Yellow Emerald Mining Company

Production ceases
After seven (7) years of production, the mine producing this extraordinary materiel had to close. It was becoming too dangerous, and the gemstones coming out were not the high-grade Emeryl is known of the offering. Almost seven years to the day of the discovery, Emeryl is no longer being mined. Luckily in those 7 years, we did produce 8,000+ gemstones and still have a limited supply of rough material in Brazil and a limited supply of finished, cut, and polished material in Michigan.
March 2020
Covid-19 hits
Covid-19 quickly spread throughout the entire world. Especially hard hit was the cruise line industry where any virus can spread rapidly and affect many in densely filled, compact spaces. Senior management of every cruise line immediately ordered the ships to dock and sit idle indefinitely to protect passengers and crew. All of the Emeryl jewelry and gemstones were removed from the vessels around the globe and returned to Michigan.
May 2020

Kristina Walterson
Carnival Cruise Line Passenger
I just wanted to let you know we recently purchased a Emeryl pendant while on a cruise on Carnival Cruise lines. It is a beautiful piece of jewelry and I am very proud to own it. My husband saw it in the display case and after a very informative discussion with the sales person, decided it was the perfect gift. Every time I wear it I get many comments regarding the beauty and rarity of the piece. I look forward to wearing and enjoying this lovely piece and since we are cruising again on Carnival, hopefully, we'll find another beautiful piece.

Shelly Gillespie
Royal Caribbean Passenger
Purchased a ring, earrings and necklace on our Royal Caribbean Cruise celebrating our 30th Anniversary. After attending a great presentation on the Emeryl, I fell in love with this gemstone. Patrick helped us pick out just the right pieces. I have had the pleasure of wearing them and received many great compliments. I had to send the ring out to be sized and a claw repaired. The service was amazing. No fees and great communication in the process. An absolute pleasure to deal with Patrick, and his staff. You won't be disappointed with the product or the service. Thank you Patrick and staff. The jewelry is treasured and always brings back many fond memories.
What is Emeryl?
Gemologically, Emeryl is beryl. Beryl is a gemstone species that includes Green Emerald, Blue Aquamarine, White Goshenite, Pink Morganite, and Yellow Beryl (Heliodor).
The quality of Emeryl (clarity, cut, and color) far exceeds most yellow beryl sold. To differentiate Emeryl from other yellow/golden beryl, the name “Yellow Emerald” was given this gemstone. After a long fight with US green emerald dealers who were concerned, yellow emerald may hurt their sales (yellow emerald is 10x less expensive than a similar quality green emerald). We decided to drop the term yellow emerald and just use the brand name Emeryl to distinguish this as the best heliodor (yellow/golden beryl) on the market today.
All Emeryl have 72 hand-laid facets compared to most gemstones and diamonds, which only have 58. The extra time and expertise of these precise facets help Emeryl to be more brilliant and have the appearance of yellow diamonds.
The colors of Emeryl gemstone are rich and vibrant. Yellow beryl tends to have grayish tones making it appear cloudy or dull. Emeryl varies from Yellow to yellowish-green to deep gold.
Gemstones are graded by color (as that is the most crucial characteristic), and clarity is seldom mentioned (as most colored gemstones have inclusions, especially green emerald). Yellow / Golden beryl tend to have inclusions that have a seaweed appearance or silky looking lines, which are growth tubes. Emeryl gemstones are all eye-clean and do not have visible inclusions to the naked eye. Only under powerful magnification can any inclusions be identified. Emeryl is the only brand of colored gemstone which uses the GIA grading system used exclusively for diamonds in the grading of clarity on Emeryl. Most Emeryl is VS (very slight inclusions) or VVS (very, very slight inclusions).
When you own an Emeryl gemstone, you have the highest quality yellow/golden beryl (heliodor) that is available in the world.

You can find less expensive gemstones online, there are reasons
Color does matter
These are actual and unedited images. The one on the left is yellow beryl sold by a competitor online for 70% less than ours on the right.
Clarity does matter
Most beryl gemstones sold do not look like Emeryl. Our gemstones are extraordinary clean, vibrant and clear from visible inclusions. This photo is a antique cushion cut Emeryl gemstone which is actual and unedited.
Not Emeryl
Growth tubes in beryl gemstones that look silky make most dull or cloudy looking. The above photo is from a competitor and is very typical of the quality online gem dealers sell. This photo is actual and unedited.
Cut does matter
It's not just the 72 facets on every Emeryl gemstone which make our gemstones more brilliant and reflective, it is size and placement of each which takes twice the time cutting and polishing than most gemstones. This photo is a pear shape Emeryl gemstone which is actual and unedited.
What does it take to mine a Emeryl Gemstone?
First, you must explore the vast land of Brazil, searching for indicator minerals. If you are fortunate and can find those, the hard work begins - you start digging pilot holes to find more clues that gems are hiding beneath the hardened earth's crust. After years of digging and small finds, you come across a small pocket 1200' down the small and narrow shaft.
Magically appearing, yellow and green gemstones glisten and come alive from the only light they have ever seen coming from your hard hat.
Trying to maneuver in such a tight space, you carefully start to chip away at the matrix, desperately trying not to damage any of the crystal formations.
Then you start removing the dirt. Wheelbarrow out the gem bearing ore to the surface crunched over in the 4' tall space, rolling over uneven rock path for 100 yards to the large thick rubber bucket which awaits.
As soon as the bucket is full, it is hauled up the shaft with a thin rusty cable driven by a beaten up, old, and barely operable generator. It takes 45 minutes to raise the material to surface slowly, then shoveled into a 20-year-old pickup truck.
It takes two (2) tons of ore (two pickup trucks full) to find 50 carats of material that is suitable for cutting. Out of that 50 carats of rough, only 10 carats is clean sufficient to cut a beautiful Emeryl gemstone.
After trimming the rough edges and removing included areas, you end up with only a 2-carat Emeryl gemstones, which are so bright and beautiful, and most believe it is a costly yellow diamond. Oddly, bright yellow 2-carat diamonds are tens of thousands of dollars per carat; a 2-carat Emeryl is only a few hundred dollars per carat.
