Our Warranty

What’s free for life:

Free Cleaning and Polishing*
Free Inspections*
Free Lost Stone Replacement*
*To keep your Lifetime Warranty active, please visit us for a cleaning and inspection every 4 months.
We will inspect, clean, polish and maintain your jewelry for free for as long as you own it. Cleaning ensures that your fine jewelry is always looking exceptional and inspection ensures your jewelry is protected and ready for everyday wear.

We guarantee:

  • All-metal jewelry made entirely of gold, platinum or silver
  • All merchandise made of gold or platinum that contains diamonds, rubies, sapphires, and semiprecious gemstones
  • All merchandise containing cultured pearls
  • All wedding bands made of cobalt, tungsten or titanium

When family heirlooms purchased from us are passed along within a family, the jewelry continues to be guaranteed under the warranty under the standard guidelines.

What is excluded from lifetime warranty:


Lost, stolen or abused jewelry.
Jewelry that can’t be reworked to look like new (like stainless steel).
Anything made with metals not capable of being altered like cobalt and titanium.
Warranty does not apply to lost, stolen, or abused merchandise.

Any merchandise with diamond nexus, Cubic Ziconia (CZ), diamond simulant, or gemstone simulant set within the merchandise.  Any merchandise with diamond simulant is not warranted.   No diamond simulant, CZ or Gemstone simulant will be guaranteed or warranty provided.   Diamond and gemstone simulants are exactly that – simulants and because of that they do not have all of the same exactly qualities of the genuine diamond or genuine gemstone.  Any sterling silver jewelry, including rings are excluded due to the lack of durability and softness of the metal.


If your jewelry is stolen, and you provide a police report describing the stolen jewelry, you will be able to purchase replacement jewelry at a discount. We have no desire to profit from your loss.

We recommend that you insure your jewelry against theft and total loss. If your insurance agency would prefer an appraisal on their own form, please bring in their form, the appraisal and the article of jewelry. We will be glad to complete their form free of charge.

Merchandise will not be guaranteed if it has been abused or worn out of expectations for normal, everyday wear. Examples include garbage disposal mishaps and accidental run ins with your car tire and driveway.

Jewelry not capable of being reworked to look like new is not eligible for our Lifetime Warranty. This includes non-precious materials and metals, like leather, rubber, stainless steel, carbon fiber and tungsten.

We do guarantee titanium and cobalt wedding bands for life like any other wedding band. However, due to the tremendous strength and hardness of these metals they cannot be resized.

In the event a gemstone is lost from your jewelry due to normal wear and tear, we will replace that stone as long as your warranty is valid showing cleaning and inspection records in the last 4 months. This includes smaller, accent diamonds as well as a center stone replacement.

Lifetime warranties are nontransferable to a third party unless gifted within a family.
