Pt900 Platinum Natural Ruby & Diamond Ring | Ruby 0.59ct | Diamond 0.28ct | Japanese Ring Size 17 | IDI Certified
This refined platinum ring is set with a vivid natural ruby of 0.59 carats, cut in an oval mixed cut that beautifully showcases the stone's deep crimson hue. Flanking the center stone on either side are two square princess-cut natural diamonds totaling 0.28 carats, providing a brilliant contrast that enhances the richness of the ruby.
The band is crafted in Pt900 platinum, a material prized in Japanese fine jewelry for its purity, durability, and naturally white luster that complements both colored gemstones and diamonds without competing with their brilliance. The interior of the shank is engraved with the hallmarks Pt900, D0.28, and 0.59ct, attesting to the materials and specifications of the piece.
Ruby has been revered across cultures for millennia as the "king of gemstones," symbolizing passion, vitality, and protection. Natural rubies of clean clarity and vivid color are among the most sought-after colored gemstones in the world. This stone's rich, saturated tone and excellent cut make it a compelling centerpiece for this elegant three-stone design.
The ring is accompanied by a gemological identification certificate issued by IDI (International Diamond Laboratory), confirming both the natural ruby and natural diamond.
