The Ultimate Modern Locket
The Oval Locket with Diamond Border represents the apex of Monica Rich Kosann’s locket collection — everything the brand does well, amplified to its most luxurious expression. The 18K yellow gold locket body is familiar from the brand’s other offerings, as are the sapphire crystal windows and precision hinge mechanism. What elevates this piece is the frame of pavé-set diamonds that surrounds the locket, transforming it from a beautiful keepsake into a genuine fine jewelry statement piece.
Diamond Details
The approximately 0.45 carats of pavé diamonds are set with expert precision around the oval border, creating a continuous ring of sparkle that catches light from every angle. The diamonds serve a dual purpose: they add significant visual presence that makes the locket wearable as a standalone luxury pendant, and they frame the sapphire crystal windows in a way that draws the eye toward the photos within. The G-H color and VS clarity range ensures the diamonds read as bright and clean, complementing rather than competing with the warm 18K gold.
Heirloom Engineering
Like all Monica Rich Kosann lockets, the engineering here is designed for generational transfer. The sapphire crystal windows resist scratching from anything below 9 Mohs. The 18K gold will not tarnish or degrade. The hinge mechanism is built for decades of daily use. The included 18K gold chain matches the locket’s metal, ensuring consistent aging and patina development. Every element is calibrated for pieces that will be inherited, not discarded.
The Investment Case
At $1,650, this is the most expensive piece in Monica Rich Kosann’s locket line, and the investment demands consideration. The materials alone — 18K gold, 0.45 carats of diamonds, sapphire crystal — justify a substantial portion of the price. The craftsmanship and engineering justify more. And the emotional value, which accrues over years and decades as the locket carries increasingly precious memories, is genuinely priceless. For milestone moments that deserve a lasting marker, the Oval Locket with Diamond Border is an exceptional choice.
