If you don’t see your ring size at checkout, please reach out – we create rings in all sizes.

We strongly recommend having your ring size measured by a professional jeweler or with a quality ring gauge. Fit is critical, and even a small difference in sizing can noticeably affect comfort and wear.

Paper and adjustable plastic ring sizers are often unreliable and can lead to incorrect sizing.

We pride ourselves on handcrafting limited quantities of fine jewelry using ethically sourced precious materials. We do not outsource manufacturing or mass-produce our work. Instead, each piece is individually created in our Columbus studio. We want every piece to feel intentional and personal, so please don’t hesitate to reach out. We’re always happy to discuss bespoke variations, gemstone options, or small design refinements to make your piece even more personal.

We endeavor to provide the best possible images of our work to support your decision. Many of the gemstones we use, especially Australian sapphires, have unique and complex colors. As with all natural gemstones, tone can appear slightly different across lighting conditions and screens; this variation is part of what makes each stone distinctive. If you’re looking for a particular color direction, please let us know. We’re happy to share additional photos or videos, and provide images of individual stones before setting.

It is common practice for the majority of sapphires used in jewelry to be heat-treated to enhance color and clarity. This is a permanent, irreversible treatment with no radiation, chemicals, or health risks. We use both untreated and heat-treated natural sapphires and will specifically note if we can confirm a sapphire is unheated. We do not use sapphires treated by diffusion, beryllium treatment, or other artificial enhancement methods. Our work uses only ethically sourced gemstones and high-quality diamonds. We only source conflict-free diamonds that comply with the UN Kimberley Process. Wherever possible, we use recycled precious metals and responsibly refined alloys.

Luke Hammond Jewelry is a fine jewelry brand based in Columbus, Ohio, with over a decade of experience creating jewelry in Australia and New York City. Our collections comprise rare, carefully crafted fine jewelry and objects that reimagine biological form to explore themes of impermanence, consciousness, and the connection between all living things. Each piece is produced in limited quantities, with an emphasis on sculptural detail and enduring craftsmanship.

Inspired by Luke’s work in biomedical imaging and neuroscience research, these organic designs draw on biophilia and our innate attraction to living systems to encourage reflection on what lies below the surface of our beings. The work invites a quieter kind of attention - to structure, to pattern, and to the living forms we’re shaped by.

Our mission is to create meaningful, lasting pieces that celebrate moments of love, union, and personal expression. Each piece is uniquely handcrafted using ethically sourced materials, with a focus on sublimely colored sapphires mined in Australia and the USA. We value provenance and thoughtful sourcing, and we design each piece to be worn and kept for generations.
