All set in Platinum, Black Rhodium Plated around the top. 13mm Tahitian Black Pearl in Center with a Rose Overtone that compliments the Rubies beautifully! 32 Cabochon Shape Natural Red Rubies that weigh 2.18carats total. I call it Octopus Style because the smooth yet bumpy feel that the Cabs create remind me greatly of an Octopus tentacle. It's a totally Rad Ring that would be the greatest Cocktail ring!
