brown, tan, brown

Brown, brown, and brown gemstones are attractive in chic and calm colors. These include brown diamond, smoky quartz, topaz, sphene, andalusite, axinite, and brown zircon. The impression changes depending on the shade, and you can feel the individuality. There are some that have a unique appearance, such as fire agate, and I think the colors are surprisingly deep.
