“Callisto” Colorless Round Lab-Grown Diamond Engagement Ring
Callisto centers a brilliant round colorless lab-grown diamond framed by a row of round accent diamonds, set in your choice of 14K white gold, 18K white gold, or platinum. Choose a 2 ct or 3 ct center for a clean, timeless silhouette that draws light from every angle.
For every occasion. Callisto is made for the milestones—engagements, anniversaries, and celebrations worth remembering—yet its understated brilliance makes it just as natural worn every day. Let it be the focal point of a dressed-up evening look, or add quiet sparkle to jeans, a knit, and everyday wear. It is designed to be lived in, not saved only for special occasions.
Why lab-grown
Callisto’s diamonds are lab-grown and IGI certified—chemically, physically, and optically identical to mined diamonds, with the same fire, brilliance, and durability. The result is modern, ethically created luxury and remarkable value: a larger, higher-quality center stone you can wear and enjoy with complete confidence, every single day.
Lab-grown value
A comparable 2 ct colorless natural diamond of this clarity and cut would typically cost $30,000 or more on its own. Callisto delivers that same colorless, brilliant presence—as a complete ring—starting at $2,670. The 3 ct center offers a scale of diamond that is genuinely rare in nature, at a fraction of the natural-market price.
