Platinum Rhodolite Garnet RingThis rhodolite garnet has a sparkling plum colour that is deep and intense. Garnet is the birthstone for January and while many people are familiar with the reddish brown variety, garnets come in a wide variety of colours from yellow and orange, through red, purple and pink to green. We love the bright flashes of vibrant red in this gemstone. It is octagonal cut which is rectangular with the corners cut off to give it eight sides. It measures 7. 6mm
