A Firth Diamond

Your Best Diamond Selection

A diamond purchase is special. That's why we stand behind each diamond purchase with a total security program that includes a written appraisal, free inspection and cleaning, and a guarantee against mounting defects in both materials and workmanship- and the kind of trust that could only come from serving more than four generations in the community.

Four Generations of Quality, Service, and Trust

Since 1946, Firth Jewelers has sold fine jewelry to the people of Western New York. Growing from a simple, one-room store on East Falls Street in Niagara Falls, Firth's now employs a large professional staff which includes a registered gemologist and a custom jewelry design team. As a family-owned business, each generation has maintained the tradition of quality, service, and trust that has made Firth's one of the region's most successful jewelry businesses.

Diamonds Really are Forever. So is our Guarantee 

At the time of purchase, we formally appraise your diamond. Signed and dated, Firth's written appraisal is placed in the Diamond Book Registry, where it can easily be retrieved for insurance or estate purposes. Your Firth mounting is automatically guaranteed against any defects from materials and workmanship. That means, in the unlikely event of a mounting defect, we'll replace your lost or damaged diamond free of charge.

The Firth Forever Guarantee

All diamond solitaire pendants, stud earrings, and center diamond engagement rings you give the person you love from Firth Jewelers feature the "Firth Forever" guarantee. It's true. At any time, you can "upgrade" those pieces and get full credit for your purchase price toward your even finer jewelry...for life! So you can't possibly make a wrong choice. That's guaranteed gift-giving success! Only from Firth's.

Return Policy

A full refund will be given on your Firth diamond purchase, provided application is made within 30 days of the purchase as per your latest dated receipt and provided the jewelry being returned is free of damage or any alteration.

Repair and Protection Policy

Firth's provides free, lifetime mounting inspection and cleaning. A mounting inspection includes checking all prongs and other wear to ensure the security of your diamond. Each semi-annual inspection is recorded in your Diamond Book Registry. This will be your assurance to prevent loss due to normal wear. If any diamond (either center or side stone) is lost from the jewelry as a result of the defect in the mounting, Firth's will replace the diamond with another diamond of comparable quality and equal value. If repair, resizing, or resetting is required, Firth's professional goldsmiths will service your ring promptly and at Firth's affordable prices
