I came here to get some of my grandmothers inherited jewelry evaluated and it was an amazing experience! Yossi and Jamie were very kind and welcoming and they gave a very fair price for my pieces, definitely recommend to all!
Yet another amazing experience i had at Benadato Trading Co, I was able to get my grandma's vintage necklace made down to a shorter necklace and a bracelet! Not to mention they also helped me customize my wife's wedding ring. Definitely come down to Benadato Trading Co for anything jewelry!!
The owners are the nicest people. They took their time and they were very kind and patient. I highly recommend!
Straight shooters, which I appreciated.
Incredibly professional and knowledge. Great experience all around!
I had a wonderful experience at Benadato Trading Co. Yossi was friendly, professional, and very knowledgeable. Previously, I took some jewelry to a jewelry store and received a bid. I gave Yossi the same items, and his bid was higher, thus demonstrating his honesty. Not only did I feel comfortable the entire time I was there, It was an enjoyable and memorable experience. Highest rating.
Absolutely phenomenal service. The entire process was professional to a degree that you feel when you are shopping in couture stores. Yossi and his staff all introduced themselves, I felt comfortable, respected, and the offer was beyond what I even expected to receive. Tip: go to the elevator inside and go to the 5th floor!
Yossi and Jamie were incredibly knowledgeable and honest. Working with them was a great experience and will be back.
Thank you for the knowledge and the sell of my rolex
I had a great experience with Bendato Trading Company! I inherited some items and was referred here to see if I might be able to sell a few things. I had the pleasure of meeting the owner, Yossi, as well as Keller. Yossi was very knowledgeable, friendly, and took the time to walk me through the process, which I really appreciated. He made the experience comfortable and straightforward, and I felt good about my decision to sell some of my rings. I’m grateful for the time and guidance he provided. If I ever have other items I’m considering selling in the future, I will definitely be returning to Bendato Trading Company. I highly recommend them to anyone looking for a knowledgeable and friendly team to work with!
Very informative and fair, helpful staff.
⭐️⭐️⭐️⭐️⭐️ I truly cannot say enough wonderful things about my experience with Benadato Trading Co., especially Yossi, Jamie, and their amazing coin expert (whose name I unfortunately forgot!). My grandmother recently passed away and left me a collection of jewelry, gold, and coins. I was still grieving her loss and had never sold gold before, so I honestly had no idea what to expect going into this experience. From the moment I walked in, I felt incredibly welcomed and comfortable. Before we even talked business, Yossi and I spent nearly 30 minutes chatting about AI and connecting on a personal level. That alone meant so much to me. It never felt transactional, and that genuine human connection made all the difference during an emotional time. When it came time to evaluate everything, Yossi and Jamie were absolutely wonderful. They patiently walked me through their entire process, carefully evaluated and priced everything, and explained how they arrived at their offers. Their transparency was incredibly refreshing, and not once did I feel pressured or obligated to sell anything. I ultimately sold nearly $8,000 worth of gold and walked away feeling confident, respected, and genuinely grateful for the entire experience. What stood out most wasn't just the fair pricing, but the kindness, honesty, and care they showed me throughout the process. Selling jewelry that belonged to someone you love can be emotional, and they handled everything with such compassion and professionalism. Yossi, Jamie, and the entire team have absolutely earned my trust. If you're considering selling gold, jewelry, or coins, I cannot recommend Benadato Trading Co. enough! Thank you all for turning what could have been an overwhelming experience into such a positive and memorable one.
I brought a diamond ring into Benadato Trading Co. about a month ago, after the company was recommended to me by an appraiser who had valued my ring and I had expressed interest in selling it. He said they would be very fair in the price they would buy it from me. Well, not only were they fair, but Yossi, the owner, and Jamie, Yossi's right hand lady were friendly, efficient during the sale and purchase, and very good at making me feel at home and at ease during my time there. I had taken my ring to another jeweler, before going to see Yossi and Jamie, who offered me much less, and a retail shop in the area whose jeweler also offered me considerably less. I urge anyone looking to sell jewelry to give Benedato Trading a call and I know you will walk away happy!
Fabulous people and honest! Thank you!
Yossi and his team were kind, knowledgeable, and honestly so much fun to work with. They were clear about gold values and the value of non-gold pieces we brought it, explaining things to us above and beyond what we expected. Would highly recommend visiting them if you have gold pieces you are looking to sell or value.
Very helpful in selling my ring!
Great service!! Fast professional and fare
Yossi is truly the best in the business. I couldn’t have asked for a better experience from start to finish. He took the time to explain everything about my ring, walked me through the GIA report, and clearly explained the pros/cons, and different options available to me. What I appreciated most was how straightforward and transparent he was throughout the entire process. He showed me what my diamond could realistically sell for on the open market and negotiated fairly with me until we were able to put together a deal I felt really good about. I trusted him with my ring while it was sent to GIA for about a week, and as soon as it came back, everything was completed exactly as promised and I was paid the remaining balance. The entire process was professional, transparent, and seamless. If you’re considering selling a diamond or fine jewelry, I honestly wouldn’t waste your time taking it anywhere else. Go see Yossi. He’s knowledgeable, fair, trustworthy, and genuinely exceptional at what he does. Highly recommend!
The customer service was amazing, they were very helpful and professional.
I recently had a piece of jewelry evaluated and sold to Benadato Trading Co. Everyone there, especially Yossi were extremely helpful, patient, and friendly. The whole process was easy. They took their time to explain everything to me and were extremely fair. I would highly recommend. Thanks Yossi!

Forget glistening facets and blinding sparkle. In the hushed, opulent corners of the gem world, whispers circulate of a different kind of diamond. Not one that catches the light, but one that devours it whole: the black diamond. And those who seek these enigmatic stones are a breed apart, their motives veiled in as much mystery as the gems themselves.
Imagine, if you will, a dimly lit auction room. Velvet drapes cloak the walls, obscuring the outside world. A hush falls as a black velvet box is placed on the podium. Inside, nestled on a bed of black satin, lies a single black diamond, the size of a raven’s eye. It absorbs the light, a bottomless pit glinting with an inner, forbidden fire.
So, are you ready to descend with us? Fasten your seatbelts, for we’re about to embark on a journey into the enigmatic realm of black diamond buyers, where the shadows hold beautiful secrets.
What are Black Diamonds?
Black diamonds, unlike their sparkling counterparts, aren’t a cut of diamond, but a unique and rare variety distinguished by their opaque, deep black color. They hold a distinct charm, often described as mysterious and alluring, and have gained increasing popularity in recent years.
Beyond their physical properties, black diamonds hold a certain mystique. Some cultures associate them with protection, strength, and even good luck. Their dark beauty has also captivated the fashion world, with black diamond jewelry becoming increasingly popular for its modern and edgy aesthetic.
Black diamonds are graded differently from colorless diamonds, focusing on their color intensity, cut, and clarity.
When choosing black diamonds for jewelry, consider the desired level of black, as some have subtle variations.
Black diamonds require special care, as their rough surface can trap dirt and oils more easily than colorless diamonds.
Types of Black Diamonds
Black diamonds, with their captivating darkness, come in three main types, each with its own unique story and characteristics:
Natural Black Diamonds
These are the crown jewels of the black diamond world, forged under intense pressure and heat deep within the Earth. Their mesmerizing blackness comes from a natural sprinkle of minerals like graphite or osbornite, creating a starry, almost galactic appearance. Each stone is a one-of-a-kind masterpiece, holding the secrets of the universe within its facets.
Treated Black Diamonds
Unlike their natural counterparts, these diamonds start out brown or gray and undergo a special high-heat treatment. This process enhances their color, resulting in a deeper, more consistent black hue. Think of them as diamonds in disguise, unlocking their hidden potential through transformation. While not as rare or valuable as natural diamonds, they offer a more accessible option for those drawn to the allure of darkness.
Man-Made Black Diamonds
Technically not diamonds at all, these beauties are called Cubic Zirconia (CZ). They’re created in a lab under controlled conditions, replicating the look of black diamonds at a fraction of the cost. Think of them as the versatile actors of the diamond world, offering a modern and affordable alternative for those who want to embrace the enigmatic charm of black without breaking the bank.
Each type of black diamond holds its own charm and appeal. Whether you seek the rareness of a natural gem, the affordability of a treated stone, or the modernity of a man-made marvel, the captivating world of black diamonds has a treasure waiting to be discovered. Remember, when choosing your black diamond, consider its origin, clarity, cut, and intended use. With a little knowledge and a touch of intrigue, you’ll be well on your way to unlocking the secrets these captivating gems hold within their darkness.
Creation of Black Diamonds
Black diamonds, unlike their sparkling white counterparts, hold a unique allure. Their enigmatic darkness whispers tales of rarity and understated elegance. But beneath their captivating surface lies a story of formation, craftsmanship, and even a touch of transformation.
Black diamonds come in three forms: those blessed by nature and those sculpted by human expertise. Natural ones, born under immense pressure like their white cousins, carry a secret within – a graphite inclusion that paints their world in shades of ebony. These gems, found only in pockets of the Earth, are rare treasures, each showcasing nature’s artistry.
For those seeking a more accessible path, treated black diamonds offer an alternative. Low-value white diamonds undergo a metamorphosis, kissed by high heat or radiation, to emerge as sleek black beauties. Techniques like CVD (chemical vapor deposition) and HPHT (high-pressure high temperature) unlock the hidden potential within these stones.
Nature’s black diamonds, with their intricate internal structures, pose a challenge to even the most skilled cutters. Their polycrystalline nature demands patience and precision, making each facet a testament to human craftsmanship. Treated diamonds, on the other hand, hold less mystery, allowing for easier shaping and polishing.
The traditional diamond grading system based on the 4Cs – cut, color, clarity, and carat – takes a backseat when it comes to black diamonds. Their opaque nature renders color variations and sparkle almost non-existent. Clarity, too, takes a different form, with inclusions becoming integral to their character. The true value lies in the mastery of the cut, where each facet amplifies the captivating darkness.
Black diamonds, whether nature’s masterpiece or human-aided transformation, offer a captivating alternative to the traditional sparkle. Their dark allure whispers of mystery and sophistication, inviting the wearer to embrace a different kind of brilliance. So, the next time you encounter these enigmatic gems, remember the journey they have taken, from the depths of the Earth to the delicate touch of the cutter, each step adding to their captivating story.
Estimating Black Diamond’s Value
Before approaching diamonds buyers you will need to estimate the value of your black diamonds, which involves considering key factors such as carat weight, cut, color, shape, and treatment. Carat weight is crucial, with larger black diamonds generally commanding higher prices. The cut, although often non-traditional due to the diamond’s opaque nature, can impact its appearance and value. Black diamonds, varying from dark gray to opaque black, may exhibit hints of other colors, influencing their worth. Unique shapes and custom cuts can add to their desirability. Natural black diamonds are typically more valuable than treated ones, and any enhancements should be disclosed. The setting, craftsmanship, and market trends also play roles in determining value. Certification from a reputable gemological laboratory can provide essential information for a more accurate estimate. Consulting a professional gemologist or diamond appraiser is advisable for a comprehensive evaluation of a black diamond’s worth based on its specific attributes and prevailing market conditions.
