Ask a Gemologist - Q & A

Quick answers to the most frequently asked questions about GemLab's location, process and services.


Where Are We Located?

We are located on 47th Street in New York City’s Diamond District. Over 90% of the world’s diamonds pass through the Diamond District in one shape or another. From diamond cutting to jewelry manufacturing, this is where all the excitement happens, and we get to see it first hand and personally share our own experiences with you.

Why Choose GAL?

We have maintained the utmost level of professionalism and expert evaluations for over 30 years. We have no vested interest in the outcome of your appraisal; therefore you will receive a fair and unbiased evaluation. Most importantly though, because we are in the heart of New York City’s Diamond District, we see changes first hand in market costs, new gemstone treatments and the methods to identify them, along with important market trends, all of which help us assure the highest degree of accuracy possible.

Do My Gemstones or Jewelry Items Ever Leave My Sight?

Rarely ever will you need to leave the item. The whole process is done right in front of you. Whether you want to just relax and read a magazine, or immerse yourself in the process by asking as many questions as you want answered about the piece itself or the jewelry industry in general, this should be a pleasant, care free, and most of all, informative experience.

How Long Does The Appraisal Take?

Generally the appraisal process will only take 20-30 minutes per item when you bring the item in. Of course this depends on the complexity of the piece and level of difficulty in the identification of some gemstones, but for the most part, an appraisal can be finished within the time you have for your lunch break. If you are submitting your piece from somewhere other than the Tri-State area, allow 5-7 business days before it will be completed. A more specific time frame will be discussed prior to submission.

What Do I Receive by Getting an Appraisal From GAL?

Aside from the piece of mind and loads more knowledge of your items than before you came in, you will receive a full, comprehensive appraisal, which includes a detailed description of the item(s), in-depth measurements, color and clarity quality, a high resolution image, and of course the value. You will also benefit from ongoing support from GAL. Whether you need an update of your existing appraisal by GAL, or if you have any questions regarding any of your jewelry or gemstone needs, we encourage you to reach out to your Gemologist anytime.

Do I need my appraisal updated?

Yes, the value of diamonds, gemstones, and precious metals are constantly changing, and reflecting the true value of the item is very important. If it is insured for too little, you are left with more out of pocket expenses. It is also in your best interest if you are getting ready to sell the item. If the value hasn’t been updated in some time, how will you know you are getting the most money for it?

When Do I Need To Update My Appraisal?

Yes, the value of diamonds, gemstones, and precious metals are constantly changing, and reflecting the true value of the item is very important. If it is insured for too little, you are left with more out of pocket expenses. It is also in your best interest if you are getting ready to sell the item. If the value hasn’t been updated in some time, how will you know you are getting the most money for it?  By having your items appraised by us, you will benefit from updated appraisals for a very modest fee.

Why can’t I just have the jewelry store I bought it from provide me with an appraisal?

Simply put…jewelers are not appraisers. Appraisals from the place you bought the piece from are unavoidably biased. The information might not exactly depict the qualities and details of the piece. Even when the appraisal information happens to be accurate, the value is usually highly inflated, which will cause you to have higher monthly premiums when you go to insure the item.

Are we recognized by insurance companies?

Yes, we are recognized by most insurance companies worldwide and are on a list of preferred appraisers for several of them. If you need a recommendation of the best insurance company that best suits your needs, please feel free to ask one of our Gemologists. We are here to make the entire process as stress free as possible.
