Antique Platinum Solitaire Ring with Olive Green Diamond

Few diamond rings are as mysterious and captivating as this antique piece. Crafted from solid platinum around the turn of the 20th century, it features a single old European-cut diamond weighing just over 1/2 carat. This unique diamond is not colorless; it is a rare fancy-colored stone that has been GIA-certified as having a fancy deep color with the rarest intensity. The diamond is described as “green-yellow,” showcasing a warm olive green hue. Under different lighting, it can appear more army green or take on a golden brown tint.

While it’s not a color-changing gemstone, this diamond exhibits an unusual color shift that is quite remarkable. The earthy green tone makes it a perfect neutral, making this ring an ideal alternative engagement option for someone seeking something exceptional. The ring is size eight but can easily be resized to fit any finger.
