Timothy E. Quigley, owner and founder of TQ Diamonds, unknowingly began his career with a simple childlike fascination with rocks and minerals. He began gathering and collecting gemstones at the age of nine. His intense fascination with gemstones catapulted him towards his dream career. Tim entered the jewelry industry as a salesperson for a local jeweler in 1985. Two short years later, he opened the doors of TQ Diamonds.

Tim's business philosophy is based on outstanding service and the finest quality products. As an independent jeweler, Tim feels he can offer his clients much more than other jewelry store chains. Therefore, he hand selects every diamond and precious gem he sells. In addition, Tim developed a keen eye and deep appreciation for custom designed jewelry. He knows his clients are looking for unique pieces of jewelry that express their thoughts and ideas.

Tim has brought custom design to a new level with TQ Diamonds. TQ Diamond's creative team consists of 3 designers/goldsmiths and 7 professional sales associates. TQ Diamonds’ knowledgeable staff encourages their clients to ask questions and to help create their own jewelry masterpieces from start to finish. TQ Diamonds is the premier custom design jeweler in the Midwest.

Eyeglasses Repair - Laser welding

Broken glasses?

Don't worry; T. Q. Diamonds is here to help!

T. Q. Diamonds, located in the heart of the Midwest (Madison, Wisconsin) , is pleased to offer eyeglass and sunglass repair with the advanced technology of our laser welder. Since 2003, we have fixed thousands of eyeglass frames with a 99% success rate.

The Laser Welder can repair virtually any break on almost any type of metal, including Titanium. With this awesome new technology, solder and a torch are no longer needed. The Laser simply shoots a beam of light, which actually welds the two pieces together producing little to no heat. A filler of gold, platinum, silver or titanium wire is then used in the Laser to fill the groove where the two broken pieces were joined. A laser weld is eighty-six percent stronger than a traditional solder. In addition, with the laser, T. Q. Diamonds can fix breaks that wouldn't be possible with solder, such as Titanium (which cannot take heat) , glasses that have a finish, or glasses with a plastic bottom to hold the lens in place.

We are now offering mail-in repairs, so that we can service you no matter where you're located! With two laser technicians working 6 days per week, we are able to offer same day shipping if we receive your glasses by noon. At just $45 with free shipping, this is definitely less expensive than getting new glasses! In addition, we give you a 30-day warranty on the weld. If it doesn't hold, simply send your glasses back to us for a second repair.

We will send your glasses back via USPS First Class Mail at our own expense. We do not provide insurance, but offer it to you for an additional cost. Please refer to the order form for insurance pricing. Since eyeglasses are generally very expensive items, we highly recommend that you insure your package! We are not responsible for glasses that are lost or broken in the mail.

  • I would recommend this business
  • Locally owned, great personal service, nice to work with knowledgable person!
  • Tacori so popular the prices aren't too flexible

WOW! Worked with Lora - she's been there over 14 years and 28+ years in the jewelry business. Her experience save us time and money. She brought in some great diamonds that fit our budget, got the Tacori ordered for us, got us approved (literally in minutes) for no interest financing for 12 months and the ring came earlier than promised! Not only did we get free financing but we have a shot at getting our rings free if it snows more than 3" on New Years Eve. Make sure you ask Lora about their snow promotion in November and December! Great website too - tqdiamonds.com. They offer a whole bunch of things like compliementary gift wrapping, jewelry inspection and cleaning, great warranties - all because they are family and locally owned!
