TGS offers appraisals of jewelry, diamonds, gemstones, and watches (and much more) that can be used for many different situations such as:


  • Insurance to cover loss, damage, or theft

  • Estate tax evaluation

  • Value comparison

  • Casualty loss

  • Dissolution of marriage (divorce)

  • Collateral

  • Barter purposes

We are the only company in texas that offers diamond laser inscripition services to the public. Laser inscription is microscopic -- totally invisible to the naked eye . It can only be seen with a jeweler's 10x magnifying loupe.

 Laser inscription is completely safe and does not change the color grade or clarity grade of a diamond.

We offer full diamond re-cuts, reshaping, and repair service for rounds and fancy shape diamonds. We can also cut your rough diamonds to provide you with the best quality yield


Diamond Cutting since 1992, Sol Perlman cutting services include recutting and repairing of chipped and broken polished loose diamonds, the manufacturing of gem rough diamonds and the processing of specialized industrial diamond applications.


Now even the most intricate and delicate jewelry
can be repaired without damaging the piece.

The low heat and the exact performance of the our laser allows our bench jeweler to be exact in the repairs, protecting the stones and enamel of the jewelry while restoring your precious heirloom to
new glory.
