The front is a large, rectangular slab set with dozens of small stones. The clear stones work like rock crystal, while the black ones create a deep, mirror-like mesh.
The thick silver bezel (approximately 80%) has retained its natural patina and subtle traces of hand-setting. This isn't "lined" jewelry—it shows the craftsmanship.
The contrast of light and black does the trick. This ring doesn't need any company—it completes the look on its own, whether paired with black denim or a white shirt.
For the record: the clear stones are quartz (rock crystal), the black ones are most likely spinel; the terms onyx/black agate are also commonly used.
