Metal: platinum (PT900) Center Stone: 7.72 ct rectangular step-cut bi-color tourmaline (green-to-copper zoning) Side Stones: 0.68 ctw near-colorless square step-cut diamonds, G–H color, VS clarity Setting Type: four-prong center with bezel-style protective rails; bar-set side diamonds Design Type: three-stone statement ring with open cathedral gallery Ring Size: US 5.5 (hallmarked) Gross Weight: 7.8 g
The ring is fabricated in high-polish PT900 and showcases a 7.72 carat rectangular step-cut tourmaline exhibiting distinct green and copper pleochroism. Four corner prongs with platinum rails secure the gem while minimizing exposure of vulnerable edges. Flanking the tourmaline are two square step-cut diamonds totaling 0.68 ctw, bar-set for a seamless profile that protects the stones and offers crisp geometric contrast. A solid cathedral gallery distributes stress and keeps the tourmaline elevated for optimal light return. The shank is flat-sided and tapers slightly toward the base, providing balance to the sizeable center.
