This is a K10 ring from Gravi, a sister brand of Sirena Azzurro. It features a garnet and a diamond inside, with a swing design that sparkles. This design is exclusive to Gravi. I purchased it and kept it in storage, unused. I ordered it in size 17 because I intended to wear it on any finger and stack it with other rings, but my body shape has changed, and it no longer fits. I am selling it. Please refer to the photos and purchase with your understanding. It will be shipped in a Gravi box.
