Everlūm
Lab-Grown
Diamonds


We’re redefining one of life’s most important traditions to be a better reflection of your love story and values. Sustainability is our passion, and Everlūm™ lab-created diamonds are an investment in a more socially and environmentally responsible future. We’re helping to push an antiquated industry forward so that your heirloom can be a true symbol of love, compassion, and integrity — without sacrificing on beauty or quality.

Believe
in Better

Only the finest lab-grown diamonds meet the Everlūm™ standards, and we don’t cut corners. We offer a curated selection of the highest quality white diamonds from the best growers worldwide.

Our Everlūm™ colored diamonds are custom grown and cut to exacting standards exclusively for Kristin Coffin Jewelry®. Available in colors you can’t find elsewhere, our colored diamonds are worthy of our exceptional rings.

We understand that a diamond is more than just its grading report. We go above and beyond just looking at the 4 C’s during our selection process. Each diamond is personally hand-selected and inspected by Kristin, and only a tiny fraction of the diamonds that pass through her hands meet the Everlūm™ standards.

We don’t believe in settling, and you shouldn’t either. Everlūm™ diamonds don’t skimp on sparkle or quality, nor do they compromise your values.

Science
Meets
Symbolism

Lab-created diamonds have the exact same chemical, optical, and physical properties as mined diamonds — all without the environmental or humanitarian costs of mining. Cultured diamonds are grown in laboratories that recreate the same environment that causes diamonds to form in the earth, which means your Everlūm™ diamond is every bit as real.
