Necklace is made with a special silk thread for your convenience to adjust the necklace at the best position that fits you. However, the thread's tenacity may wear out in time and thus we recommend replacing the thread every year. For information regarding replacing new thread for the necklace, please contact our store staff for inquiry.

For that extra personal touch, we recommend personalized engraving. It's available on most of our rings and all engraving-friendly items. We also offer polishing cloths, our own professional jewelry cleaner, and complimentary gift cards (plain or customized). You may also request a gift receipt.

Yes. On the day of shipment we'll email you shipping confirmation that includes order-tracking information. You'll be kept informed of the transportation process at every step. You may also access shipping information by using the "Order Status" link.

For U.S. orders, we currently collect sales tax for orders shipped to Hawaii, Maine, Massachusetts, Mississippi, New York, Oklahoma, Pennsylvania, Rhode Island, Vermont, Virginia and Washington State. We do collect duties and taxes when shipping to Canada and within the European Union (EU). For all other destinations overseas, customs will contact you if you owe additional taxes and duties. For more information see your "ship to" country policy

We offer complimentary cleaning and product check-up (recommended every six months) as a well-advised preemptive measure against the possibility of stone loss or damage that occurs when prongs are bent, pulled, caught, or broken during normal wear. We only ask that you cover the shipping and insurance to safely transport the ring to our facility. And as a gesture of gratitude for choosing Blue Nile, we'll cover the shipping back to you.

Diamond prices are determined by unpredictable fluctuations in the market which can happen at any time without warning. So, fiscally speaking, it's anyone's guess. But if you‘re currently in the market for a diamond, and you've chosen one but are reluctant to finalize the purchase, contact us within 72 hours and we'll lock in the price for you. However, in all fairness, we reserve the right to correct pricing errors if - and when - they occur. Helpful hint: If you happen to find a diamond that is very similar to another (but priced lower) - and you wish to prevent a savvy visitor to our site who will identify it and purchase it quickly - we recommend that you ask us to place it on a 48-hour reserve.

We're constantly sourcing diamonds to offer the finest quality at the most competitive prices. In the industry, prices are based on suppliers' buying power and market conditions at the time of sourcing. We price our diamonds based on our cost, not the current market or solely by its quality and size. And regardless of how competitively a diamond is priced at Blue Nile, we always pass the savings onto you. Helpful hint: Select customers tend to quickly identify the best values of a seemingly identical diamond. So if you are interested in a diamond that appears to be of a higher value, call one of our diamond experts to review its characteristics. If the diamonds are virtually the same - yet one's value stands out from the other - they tend to sell fast. If you request additional time to decide, our diamond experts will grant you a (no-obligation) 24 or 48-hour hold on the diamond in question.

We provide complimentary resizing for Build Your Own Rings™, and Diamond Bands when within the manufacturer's recommended sizing range, during the first year. Simply contact a Diamond & Jewelry Consultant at 800-242-2728 to arrange for your free resize. Diamond and gemstone eternity rings with a specific number of gemstones per finger size; milgrain or ornate bands, some silver rings, or rings with alternative metals such as Tungsten cannot be resized. We are happy to exchange your ring for another size within 30 days of purchase. It is important to note that should you opt for an exchange, your new ring may contain a different number of gemstones, diamonds, or a reduction or increase in precious metal weight which may cause a change in the price.
