Cartier Maillon Panthère 18K Yellow Gold Diamond Band Ring, 1.40ct, Original Box

Three rows of bead-set diamonds run the full width of this Cartier Maillon Panthère band, each link articulated so the ring flexes slightly rather than sitting as a rigid hoop; a signature of the Maillon construction, borrowed from Cartier's link-bracelet designs. Ninety round brilliant diamonds, F color and VS1 clarity, pack the surface edge to edge, giving the piece a continuous, unbroken sparkle rather than a bordered pavé pattern. At 8mm wide, this reads as a substantial, architectural band rather than a delicate accent ring. The reverse carries Cartier's full authentication: the maker's signature, French "750" gold fineness mark, eagle's head import hallmark, and individual serial number, alongside the original Cartier presentation box.

Excellent condition; no visible wear, damage, or loose stones in photographs. Note: this ring cannot be sized up, only down, due to its articulated link construction. Stamped Cartier, 750, serial 732999. Size 6. Weighs 9.36 grams total.
