The Story of The Olympia

The Olympia solitaire engagement ring features a 14K white and yellow gold setting designed specifically for a square 3.00 x 3.00 mm lab-grown diamond. Crafted in our woman-owned Brooklyn studio, this ring setting is made of solid recycled gold and offers a clean, modern foundation for your center stone.

This solitaire ring is set in a classic prong style that securely holds your square diamond, showcasing its brilliance and sharp lines. The shank is elegantly simple with a smooth profile, highlighting expert craftsmanship and attention to detail. Its understated design makes it versatile and distinctive within our collection.

Made from 100% recycled gold with conflict-free and ethically sourced materials, this ring setting aligns with sustainable luxury values. It is IGI and GIA certified ready, ensuring your lab-grown diamond meets the highest standards. As a woman-owned studio based in Williamsburg, Brooklyn, we prioritize ethical practices and quality in every piece.

The Olympia solitaire ring setting is available in multiple sizes to provide an ideal fit. The setting comes unset, allowing you to choose your lab-grown diamond or gemstone to customize your piece. We are happy to assist you through the selection and sizing process.

Every piece is made to order. Once your order is placed, we'll send you a confirmation email with your estimated completion date. Most orders ship within 2 to 3 weeks, and we'll notify you immediately when yours is on its way.

We also offer returns and exchanges within 60 days of purchase (custom designs may vary). Returns are free with our prepaid shipping label, and in-store purchases can be returned at our Williamsburg studio. Read our full Refund Policy and Warranty →
Lab-grown diamonds are more affordable and sustainable than natural diamonds. They offer the same brilliance and durability, but without the environmental or ethical costs. Learn more about the economics of lab-grown vs natural diamonds →
Yes, we ship worldwide. All orders are carefully packaged and fully insured for transit. Domestic orders within the United States typically arrive within 7 to 14 business days. International shipping times vary by destination, generally 15 to 27 business days. Customs duties and import taxes may apply depending on your country and are the responsibility of the recipient. 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.
