The Story of Long Bond

The Long Bond Seven-Stone Hidden Heart Anniversary Band is a slim eternity band crafted in 14K white gold. Featuring 5 carats total weight of lab-grown diamonds, this piece is designed and made in our woman-owned Brooklyn studio.

This anniversary band showcases a hidden heart motif set within a polished 2mm shank. The diamonds are set securely with a classic prong setting that highlights their brilliance, while the slim profile offers an elegant, refined fit. Expert craftsmanship ensures durability and distinctiveness in every detail.

Made from 100% recycled solid 14K white gold, this band is ethically sourced and conflict-free. Our lab-grown diamonds are IGI and GIA certified ready, reflecting our commitment to transparency and sustainability. Every piece is crafted with care in Williamsburg, Brooklyn by our woman-owned fine jewelry studio.

The Long Bond band is available in a range of sizes to ensure a comfortable fit. The prong setting style keeps the diamonds secure while allowing maximum light for sparkle. Choose this slim anniversary band for a meaningful, responsibly made symbol of your connection.

We ship within the United States, with a $40 flat insured shipping fee on every order and a signature required on delivery. Domestic orders typically arrive within 7 to 14 business days. We do not currently offer international shipping. Contact us before ordering if you have questions about shipping to your location.
Yes — every ring we make uses 100% recycled solid gold. Recycled gold is chemically and physically identical to newly mined gold, but its production avoids the environmental destruction and human rights concerns associated with gold mining. Choosing recycled gold is one of the most meaningful steps you can take toward an ethical engagement ring. It is a commitment we make on every piece, not an optional upgrade.
Yes. Haejin Jewelry is a woman-owned independent business founded and operated in Brooklyn, New York. We curate every piece and inspect every ring before it ships to you. As a small independent jeweler, we pour genuine care into every order — from the sourcing of our recycled gold to the final quality check. When you buy from Haejin Jewelry you are supporting a local Brooklyn business, not a corporate chain.
The number refers to gold purity. 14K gold is 58.3% pure gold mixed with other metals for strength and durability — it is harder, more scratch-resistant, and more affordable. 18K gold is 75% pure gold, giving it a slightly richer, deeper color and a softer feel, but it is more expensive and slightly more prone to scratching over time. For everyday wear engagement rings, 14K is often the practical choice. For those who prioritize the highest gold content and richest color, 18K is worth the premium. Both are available in white, yellow, and rose gold at Haejin Jewelry.
An unset ring setting — also called a mounting — is the metal portion of the ring without a center stone. It holds the diamond or gemstone but is sold separately so you can choose exactly the stone you want. At Haejin Jewelry, our ring settings are designed to be paired with a lab-grown diamond or gemstone of your choice through our online ring builder. This gives you full control over the size, shape, and quality of your center stone.
Most of our settings are designed for a specific center stone shape and size range. Our online ring builder automatically shows you compatible lab-grown diamonds for each setting — so you’ll only see stones that will fit perfectly. If you have a specific stone in mind, our team is happy to help you find the right setting match. Contact us or visit our Williamsburg Brooklyn studio for personalized guidance.
Most custom engagement rings are completed within 3 to 4 weeks from the time your order is placed. Rush options may be available depending on the setting and stone selected — contact us to discuss your timeline. Each ring is made to order by skilled artisans and carefully inspected before shipping. We recommend ordering at least 6 weeks before your target date to allow time for sizing adjustments if needed.
Our ring settings are available in sizes 4 through 12, including quarter sizes such as 4.25, 4.5, 4.75, and so on. Half and quarter sizes are available on most styles. If you are between sizes or unsure of your size, we recommend our free ring sizing guide or visiting our Williamsburg Brooklyn studio for an in-person fitting. We can also advise on sizing adjustments after your ring is complete.
Our engagement ring settings are available in 10K, 14K, and 18K gold in white, yellow, and rose, as well as platinum and two-tone combinations. 14K white gold is our most popular choice — it offers excellent durability, a bright white finish, and a lower price point than platinum. 18K gold has a richer color and higher gold content. Platinum is the most durable and hypoallergenic option, ideal for those with metal sensitivities. All metals are 100% recycled solid gold or platinum — never plated.
Yes. Most ring styles can be resized one to two sizes up or down after delivery. Some designs — including eternity bands and rings with stones set all the way around — cannot be resized without affecting the stone setting, so we strongly recommend confirming your size before ordering those styles. If you need a resize, contact us within 60 days of receiving your ring and we will advise on the best approach. We also offer complimentary first-time resizing on select styles — ask us when you order.
Each ring setting is designed for a specific center stone shape and size range. Our online ring builder automatically filters compatible lab-grown diamonds and gemstones for whichever setting you select — so you only see stones that will fit perfectly. Common shapes include round, oval, cushion, emerald, pear, marquise, heart, and radiant. The compatible shape is listed on every setting’s product page under Specifications. If you have a stone already and want to find the right setting for it, contact us and we will help you find the perfect match.
