An Art Deco jelly opal ring in a diamond surround, in platinum.

The term jelly opal refers to a variety of precious opal prized for its exceptional translucency, which allows its spectral colors to appear suspended within the stone rather than confined to its surface. In this ring, the cabochon cut accentuates this effect, lending the gem a luminous, almost liquid appearance. Vivid flashes of red, green, blue, and orange appear to float within the stone, shifting gently at any movement. The opal is framed by a continuous border of old-cut diamonds, their brilliant white appearance providing a striking contrast to the opal's ethereal quality.
