Round D-Block Tanzanite & Diamond 18K Ring

Write a Review

Talk about sparkle! This beautiful gemstone ring has one of the most sought-after gemstones – a round brilliant cut natural Tanzanite. Round cuts are rare with this gemstone as the cutting of all rough Tanzanite is to ensure maximum carat weight. There is a lot of carat weight waste with a round cut over 2 carats, which is why this is unusual to see.

We put this beautiful gemstone in our baguette setting design - with many baguettes on both sides of the gemstone and diamonds on the setting basket for sparkle everywhere. The diamonds are clean and colorless, and are set in 18K white gold that just complements this beautiful gemstone.

This gemstone is AAA (best) quality (best color, clarity), and from D-Block.

As usual with California Girl Jewelry, the sizing is complementary, the shipping is free and the ring comes for presentation in a beautiful rosewood gift box.

AAA Top Gem

Zoisite (the scientific name for Tanzanite) is often called a “Single Generation Gemstone”. Most gemologists agree that this gemstone will be extinct in approximately 24 months. It is found in only one spot on earth, Tanzania Africa, and they are on their last area to mine it ('D' Block). No other sources for this beautiful gemstone have been found, making it a solid investment.

A truly one-of-a-kind Designer Ring from California Girl Jewelry!

Tanzanite Legend and Lore*

Tanzanite is purported to be a wonderful tool to encourage recovery from severe illness or stress. Some believe it strengthens the immune system, regenerates cells, and treats the heart, spleen, pancreas, lungs, head, throat, and chest. The stone is also thought by some to be a great detoxifier. Others believe it has the ability to neutralize over acidification and reduce inflammation, stimulates fertility and heals diseases of the ovaries. It has been said that it is extremely beneficial to wear or place the tanzanite on the body in direct contact with the skin, where appropriate for long periods of time, as it is a slow acting stone.
