Customer Services

We’ve been serving our loyal NJ Customers for over 18 years. We may not be in the neighborhood, but we promise the same exceptional customer service.

Diamond Setting

Once you have selected your engagement ring and diamond, they will be shipped directly to our store for thorough evaluation and professional setting -- so we can insure that your piece is perfect upon arrival. To help you plan when to expect your order, you'll find an estimated delivery time listed under the shipping tab of each product detail page.

Please note that although we will do the best we can to accommodate your needs, any rings that have been set with a diamond, may be non-returnable or subject to a fee for labor and restocking. Please note that loose diamond purchases include a 10-Day Return Policy. To learn more contact us at 1-609-654-2234 (Medford, NJ store) or 1-877-JGK-5510 (Online store only.)

Engraving

Currently we offer a limited selection of money clips and cuff links that can be personalized with engraving. If you are purchasing one of these items and would like to have them engraved, you will be able to indicate this during the checkout process.

Once your order has been placed, a sales associate will contact you to discuss placement, style, and pricing. Engraving comes in two standard styles; script and block lettering. Standard engraving charges are $2.00 a letter. Finally, you will receive an e-mail to confirm the engraving charge. Engraving an item will add approximately 1-2 days to delivery time.

Please note that although we will do the best we can to accommodate your needs, engraved items are non-returnable. To learn more contact us at 1-609-654-2234 (Medford, NJ store) or 1-877-JGK-5510 (Online store only.)

Appraisals

The following items include a free written insurance appraisal:
• Diamond engagement rings and wedding bands
• Diamond, gemstone, watch and pearl jewelry purchased for $1,000 and more.

An appraisal is a document stating the approximate retail replacement value of an item. It is calculated using current market data, which reflects typical retail prices. In addition to the cut, color, clarity, and carat weight of the gemstone(s), it includes the weight of precious metal included in the item, and the craftsmanship of the item.

Your insurance agency can rely on this appraisal to calculate a coverage rate for your diamond or piece of fine jewelry. Your appraisal ensures that in the case of loss, theft, or damage your insurance company will provide you with equal replacement value for your item. The more information contained in your appraisal, the more likely you are to receive the exact replacement value for that item.
