OUR TEAM

ADAM BLUESTEIN, Owner of Blue Diamond, Gemologist & Auctioneer
ADAM BLUESTEIN, Owner of Blue Diamond, Gemologist & Auctioneer

I was born into this business in 1981 in my father's shop.  I have been trading professionally for 15 years, and there is nothing I didn’t learn the hard way.  I have a degree in physics, and I love math and science. I am a GIA Diamond Graduate and my specialties include diamonds, gemstones, jewelry and metal identification.  I enjoy turning chaos into order, including whatever's in your jewelry box.  Often, I can tell you where and when it came from.  I call that “jewelry forensics”.  Pick my brain.  I'm always up for a challenge, and I love talking nerdy.

I’ve been in the jewelry business for over 8 years doing everything from managing a busy pawn shop in Los Angeles to making custom high-end jewelry here in San Antonio.  I assist in grading diamonds and evaluating the high-end jewelry that we buy. I also photograph and edit the entire 900+ item catalog for our popular, national online-auctions, and I manage our social media accounts with edgy marketing and artistic twists.  I love jewelry and, when you come in to visit us, I want to make sure that you go home with something you love, too!

I’m a collector. I’ve been collecting coins since I was knee-high to a grasshopper.  I remember going to the coin and stamp store with my dad.  While he looked at stamps, I was captivated by coins.  I started to collect Lincoln cents in 1965 with the money I made from my paper route, paying $75 for my first red 1909-S VDB. Flashing forward to now, I’ve worked in the coin industry for over 35 years.  I have extensive knowledge of bullion, world coins and currency, especially from the 19th & 20th centuries.  I look forward to meeting you and helping you to achieve your objectives.

VANESSA COLON, Jewelry & Gemstone Specialist

I am a jewelry & gemstone specialist who dabbles in creatively showcasing the luxury items at Blue Diamond. I assist customers on the retail floor with quick wit and tremendous patience. I grew up in a family of “rock hounds”. After college, I taught myself how to metal-smith and combined my love for minerals, metals, fire and rivers to create organic artistically crafted jewelry. I genuinely enjoy helping others and am a well-rounded team player. My entrepreneurial spirit and ability to excite others with my enthusiasm makes me a great addition to the Blue Diamond team.

I've been trading anything and everything professionally since 1981. I've never felt that I had a real job... it's been more like a treasure hunt. It's unlikely that you're going to show me something that I haven't seen before. I studied coin grading under Kenneth Bresset, Editor Emeritus of "A Guide Book of United States Coins" ("The Red Book") and ex-President of the American Numismatic Association. I'm happy to offer my insight to our customers about anything at all. If I don't know the answer to your question, I'll admit it. But, for the most part, I know!

TRAVIS HARRIS, Jewelry & eCommerce Specialist

I’m a jewelry and precious metal specialist who has been in the estate merchandise industry for over 8 years. I started working at an antique shop when I turned 16 and fell in love with all aspects of the business. I soon opened multiple booth shops myself, selling fine and fashion jewelry and learning all I could about business. Fast forward to now, I am an eCommerce specialist with certifications in various online applications, coding, and analytics that allow me to manage a large portion of our online sales. It'll be my pleasure to work with you!
