What is ADX's Exchange/Warranty/Upgrade Guarantee?


We offer a 30-day Money Back Guarantee on all in-stock purchases on the condition that the piece is returned in its original state and accompanied with the receipt, lab reports and appraisals.


We offer a lifetime warranty on all of our fine jewelry that covers any loss of stones cause by manufacturing defects on the condition that the item is inspected every six months. Regular cleaning and inspections are complimentary. This warranty is void if the article of jewelry has been damaged by accident, neglected, unauthorized service or other factors not due to defects in material or workmanship.


If you decide to upgrade your existing diamond, we'll apply the purchase price of your diamond towards the purchase of a new diamond. Please note that the value of your existing diamond may be affected by its condition.


If after 30 days, you are not completely satisfied, we will buy-back your purchase and work with you to find the perfect piece.

How do I go about designing a custom engagement ring or other piece of custom fine jewelry.

A custom, one-of-a-kind ring or other piece of custom fine jewelry can be created in four easy steps:

  1. Meet - Book an appointment and meet with one of our ADX diamond experts either in our office showroom or virtually.
  2. Design - Share your ideas, desires, concepts, pictures and descriptions of what you envision your piece to look like.
  3. Approve - Our master jewelers will create a wax prototype for your one-of-a-kind item based on your custom* design. We've invested in some of the most sophisticated CAD (computer aided design) technology to bring your vision to life. This is the stage where your design can be tweaked.
  4. Create - Once you've signed off on the design, your item will be brought to life in your choice of precious metal.

Simplify the process of buying the perfect engagement ring. Watch our video to learn how easy it is to create the perfect ring for the perfect person.

*Custom designs typically take between four to six weeks to be completed depending on the approval phase.

How do I sell an item?

We always offer our clients discreet and friendly service. As a trusted buyer, we pride ourselves on offering premium prices for your high quality merchandise. Whether you are selling, trading-in or trading-up, our jewelry specialists and appraisers have extensive knowledge, experience and always work to offer you the most competitive value for your items. We also offer our clients immediate payment for their item(s) and no item is too big or too small.

Our approach is always confidential and we give clients a high comfort level in our private office.

What is the difference between an appraisal and a certification?

An appraisal is an estimate for the retail replacement value of an item. It gives a brief description of the item purchased along with the value it would cost to replace the item. Some insurance companies required re-appraisals every 24-48 months. We recommend re-appraising your fine jewelry every few years.

A lab certification includes a thorough description of the diamond completed by trained gemologists with specialized equipment and includes measurement, weight and dimensions. Diamond quality characteristics such as cut, color and clarity are also specified. A diamond certificate provides an expert analysis on the quality of the diamond and is provided by an independent gemology lab. Certification is undertaken by labs that only grade diamonds and gem stones. All stones sent to the lab must be unmounted in order to obtain an accurate grading. Certified labs do not buy or sell diamonds in order to ensure that the grading is performed in an objective way. Most labs will even plot your stone meaning that a diagram of your diamond will be created outlining all of its identification marks and/or flaws.

ADX's diamonds are certified by the world's leading gemology grading labs including the Gemological Institute of America (GIA).

Is it safe to receive a diamond in the mail?

Yes and no. It is safe to receive a diamond in the mail only if the jeweler uses insured carriers (e.g. FedEx and UPS) to ship its packages and only if all shipments are insured for the full value of their contents. It's also strongly advised to ship to a business address rather than a residential address.

All ADX packages are fully insured.

Planning to ship? If so, please contact us first so that we can assist you in ensuring that you have the right insurance for the contents of your package.

How much money will I save if I choose to purchase from ADX versus a retail outlet?

The amount of money that you will save depends on the item that you purchase. At ADX, we typically sell all of our items at 40 to 60 per cent below appraised values.

How is ADX able to charge so much less than other stores?

ADX is a diamond wholesaler, not a retailer so we can save you hundreds and even thousands of dollars because we do a very large volume of business and have a very low mark-up.

We buy direct from diamond cutting factories all over the world, removing the middle-man. We're located in a smaller office showroom setting with much lower rent costs than a typical retail store, we have salaried employees versus commissioned employees and we also don't have a huge line of credit to pay interest on. All of this adds up to low overhead.

High volume and low overhead makes it possible for us to offer our clients lower prices.

Can I have my diamond laser inscribed?

Yes, ADX has diamond laser inscription services.

Most diamonds that are used as a center stone in engagement rings have inscriptions. These inscriptions are lasered onto the diamond when it is being graded by certification labs such as Gemological Institute of America (GIA).. Inscriptions are often used to identify the diamond when going in for repairs and don't damage the stone in any way.

You can inscribe a certification number or any sentiment that you wish on your diamond. Contact us or stop by our office showroom anytime during business hours.

Does ADX sell Canadian diamonds?

Yes, ADX has access to hundreds of thousands of diamonds from all over the world as well as the diamonds responsibly mined right in our own backyard.

All Canadian diamonds originate from ethical and environmentally responsible sources. They are pure and are the only diamonds in the world that can be traced back to the mine in which they were cut.

Canadian diamonds represent strong values without compromising selection and quality. They are wholly-free from violence and human rights abuses and are mined in accordance to Canada's strict mining laws.

At ADX, you can rest assured knowing that all of our diamonds are conflict-free and adhere to the guidelines set out in the Kimberly Process.

Does it cost anything to have my jewelry cleaned?

No, jewelry cleaning at ADX is always complimentary. Bring your jewelry in anytime during business hours and we will make it sparkle free of charge.
