Customer Conduct Policy

We deeply value our customers and strive to provide excellent service. To ensure a respectful environment for everyone, we maintain a zero-tolerance policy for threats, harassment, abusive language, or discriminatory behavior toward our staff. Individuals engaging in such conduct may be refused service.

Black Diamonds – New York is supported by a small team of jewelry designers and jewelers who work hard to create a positive shopping experience. We kindly ask that all interactions be conducted with mutual respect.

Military & Community Ring Program

We are proud to offer a program providing a free wedding ring to eligible U.S. military service members and individuals facing financial hardship. If you believe you qualify, please contact our team directly for more information and to submit your request.

Our Craftsmanship

Many of our pieces are made-to-order and brought to life through CAD development, custom molds, and carefully selected stones. Other designs are part of our Curated Collection and may not require a full custom CAD process, but still undergo our finishing and quality standards. Because we focus on customization and precision, most pieces require 3–20 business days for production before shipment. This allows time for sizing adjustments, engraving, stone setting, polishing, and final inspection. Every piece — regardless of category — is produced to our material standards and carefully inspected before delivery.

Personalization Services

We offer both custom-made pieces, often featuring our original, trademarked designs, and curated pieces. For all items, we stand by our quality and specialized personalization services.

Will My Finger Turn Green?

Fine Jewelry Collections: Our fine jewelry is crafted from solid gold or high-quality 925 sterling silver dipped multiple times in real gold plating for enhanced durability and appearance. These materials are designed for comfortable wear and typically do not cause green discoloration. However, because individual skin chemistry and pH levels vary, reactions can occasionally occur with any metal.

Some of our pieces are also made using a silver-platinum blend (approximately 70% silver and 30% platinum) to enhance durability and finish. We are confident in the premium materials used in our collections. For best results, please review our preventative care guidelines.

Fashion Accessories: Our fashion accessories may be crafted from materials such as alloy, zinc alloy, copper, or brass. These pieces are intended for occasional wear and may naturally fade or discolor over time, especially when exposed to moisture, sweat, perfumes, or chemicals. Individual skin chemistry may also affect how these materials react.

Allergy Disclaimer:
If you experience any skin irritation or allergic reaction, please discontinue use immediately and contact our team if you need assistance.

Order Cancellations

Our cancellation policies vary by order type. Please note that these policies are separate from our 30-day Guarantee.

• Regular Orders: Can be canceled within 24 hours of purchase, provided processing has not yet begun. For cancellation requests made after 24 hours, a fee of up to 30% of the order total may be applied. This helps cover some of the material costs we've already incurred. Please contact us immediately if you need to cancel, as orders are often processed quickly.
• Custom-Made-to-Order & Personalized Items: Once production has started, which begins immediately or within 24 hours of your purchase, these orders cannot be canceled or modified. Approved cancellation requests for custom-made items (if permitted) are subject to a cancellation fee of up to 50% of the product price to cover partial production costs.

Are Our Stones “Real Diamonds,” and Will They Pass a Diamond Test?

Natural Diamonds (mined from the earth): These are genuine diamonds formed naturally over time. They will pass standard diamond testers.

Lab-Grown Diamonds (CVD/HPHT): These are also real diamonds. They have the same chemical, physical, and optical properties as natural diamonds but are grown in a laboratory. They will also pass standard diamond testers.

Moissanite: These are real gemstones composed of silicon carbide. While it is not a natural diamond, it is widely known for its exceptional brilliance and durability. Moissanite will typically pass common handheld diamond testers due to its similar thermal properties.

Most Natural Diamonds, Lab-Grown Diamonds, and Moissanite will register positive results on standard handheld diamond testers, as these devices primarily measure thermal conductivity and basic electrical properties.

Important Note on Moissanite Testing: While Moissanite excels in these common tests due to its unique thermal and electrical characteristics, a local jeweler using specialized equipment designed for natural diamond identification (which analyzes carbon structure and specific electrical conductivity) may differentiate it from a diamond. In very rare instances, this specialized testing may not show a "diamond" result for moissanite.

Budget-Friendly Diamond Alternatives:

Our Simulated Diamonds, BDNY Diamond Alternatives, and Created Diamonds are premium diamond simulants designed to replicate the appearance of natural diamonds. These stones are crafted to provide exceptional sparkle and beauty at a more accessible price point.

Please note that diamond simulants will not pass a diamond tester, as they do not share the same physical properties as natural or lab-grown diamonds.

For a more detailed comparison of our stones, please refer to our Stone Authenticity Guide.

GEMSTONE CERTIFICATION

All our diamonds and Moissanite pieces come with independent certification:

• Natural Diamonds (0.4 carats and up): Include a GIA Certificate.
• Certified Lab-Grown Diamonds: Include an IGI Certificate or equivalent.
• Moissanite (0.50 carats and up): Include a GRA Certificate. Please note that while GRA provides detailed grading reports for Moissanite, it is not an internationally recognized gemological authority like GIA or IGI.

For coffin-cut and other special-cut diamonds, a certificate is available upon request and must be arranged before shipping.

Jewelry Upgrades

All our jewelry can be upgraded to a higher value based on your choice of:

• Metal Type: 10k-18k white, yellow, or rose gold.
• Metal Plating: Platinum, yellow gold, rhodium, and rose gold.
• Stone Type: Natural Diamonds, Moissanite, Salt and Pepper Diamonds, and CVD/HPHT Lab-Grown Diamonds.
• Stone Carat: Available in 1-5 carats.
• Stone Color: Custom colors are available for free; please contact us for details.

Solid Gold & Platinum Certificates

Certificates for solid gold and platinum jewelry are available upon request before shipping. All our solid gold and platinum jewelry can be appraised by any local jeweler. Please note that appraisal values can vary depending on various factors, including market conditions and appraisal methodology. We cannot guarantee a specific appraised value.

After-Sales & Support

Partial Order Fulfillment

For your convenience and faster delivery, we prioritize shipping ready-to-ship items first. If your order includes a personalized item along with a ready-ship piece, your ready-ship item will be dispatched immediately. If you prefer to receive all items together, we are happy to hold your shipment until your entire order is complete; just let us know.

Incorrect Item/Size Ordered

Returnable items can be returned within 30 days if unopened and unused. However, custom-made, made-to-order jewelry, eye masks, and personalized items are not eligible for return or exchange (as per our 30-Day Guarantee Exclusions). If the error was ours, we'll provide a return label; otherwise, you're responsible for return shipping costs.

Order Changes/Additions

We can modify your order as long as it hasn't left our facility. However, all custom-made orders cannot be changed or modified once production has started. Please contact customer support immediately to check your order status.

Returns for Custom-Made/Personalized Items

All sales are final for these items. If the error was made by us, we will send you the correct order or issue a refund; you may keep the item unless an inspection is needed.

Restocking Fee

While we previously offered free returns and exchanges, we encountered challenges due to an increase in returns of products showing signs of use or returned after specific event-based wear. This significantly impacted our operational sustainability and the considerable effort invested in crafting each piece. Our updated policy reflects our commitment to fair practices and maintaining quality for all customers.

Damaged Items

Should you receive a damaged item, please report it to support@blackdiamondsnewyork.com within 30 days of delivery. To qualify for a replacement or refund, a short video or photos of the damaged item(s) must be provided as proof. Damages reported beyond this 30-day window, or requests without visual proof, may not be eligible for resolution.

Jewelry Plating Information

Longevity of Plating

The longevity of plating (e.g., rose gold, yellow gold, rhodium, black plating) on your jewelry is highly individual and depends on factors such as your skin's natural oils, environmental exposure (water, soaps, chemicals), and consistent care. Plating can last from a few days to several months or even years. Plating is a temporary finish only, and faded plating is not considered a quality issue.

Common Platings & Durability

Most of our 925 silver jewelry features standard rhodium or gold plating. Rhodium plating, common across the industry, helps maintain luster and protects the base metal. Our silver jewelry with gold plating is uniquely 5x dipped in solid gold for enhanced durability. For lasting beauty and durability, we recommend our solid gold jewelry collection, where plating issues are not a concern.

Black Rhodium Plating

Black rhodium plating, applied over silver or gold, results in a rich dark gray to black color, which varies slightly based on the underlying metal. This is a highly intricate process. While we use industry-leading materials and processes, black rhodium is also a temporary finish only. Its lifespan is individual and can range from days to months or years. Complimentary re-plating for black rhodium is available for up to 3 months from delivery. Pieces beyond this warranty period are not eligible for re-plating services.

Plating Maintenance

To preserve your jewelry's appearance, professional cleaning and re-plating are recommended every 3-12 months. This service can be arranged through us or any professional jeweler.

Silver Blends (PT950 & S700 Stamps)

To ensure transparency, some of our silver jewelry is blended with platinum and marked with PT950 or S700. These pieces are composed of 70% silver and 30% platinum. While not pure platinum, our unique technology provides a feel to 100% platinum. All other silver jewelry is stamped S925 or 925, indicating 92.5% pure silver and 7.5% other high-quality metals. Should you experience any skin irritation or allergic reactions, please discontinue wearing the jewelry immediately to prioritize your skin health.

Faded Plating Returns/Refunds

Unfortunately, faded plating does not qualify for a refund. As plating is a temporary finish expected to fade over time, proper care is essential to extend its lifespan. While a refund is not applicable for faded plating, we are committed to helping resolve the issue and may offer solutions like reshipment or a complimentary professional service, depending on the item's condition.

Jewelry Care Instructions

While pure silver is naturally softer and more pliable than solid gold, our silver rings are meticulously crafted for durability. We use either a blend of 70% pure silver and 30% platinum, or 92.5% pure silver with 7.5% other high-quality metals. With proper care, these compositions ensure your jewelry will not bend easily. Please note that all silver can react uniquely to household chemicals and excessive sweating; therefore, appropriate care is essential. Learn more about how to care for your jewelry here.

Chargeback & Order Disputes

If you have any questions or concerns regarding your order, please contact our team first so we can assist you directly. Initiating a chargeback before contacting us may delay resolution and create unnecessary complications. Submitting a false chargeback (sometimes called “friendly fraud”) may violate payment processor policies and applicable laws. We work closely with payment processors to review all chargeback claims and provide documentation when necessary. Our goal is always to resolve concerns directly with you. To learn more about chargebacks and their implications, click here.
