About Tanzanite

Tanzanite is a rare gemstone found in only one place in the world—near Mount Kilimanjaro in Tanzania—making it far more limited in supply than most colored stones. Its signature blue-violet color is the result of natural trace elements and heat treatment, and the stone is prized for its pleochroism, meaning it can display different shades of blue, violet, and sometimes hints of burgundy depending on the viewing angle and light.

On the Mohs scale, tanzanite ranks **6 to 6.5 in hardness**, which makes it softer than sapphires and diamonds but still suitable for fine jewelry when thoughtfully set. Its **toughness is considered fair**, meaning it should be protected from sharp blows or daily impact. Tanzanite is best cared for by avoiding ultrasonic cleaners, steam cleaning, and harsh chemicals. Gentle cleaning with warm water, mild soap, and a soft brush is recommended, along with storing it separately to prevent scratches.

Beyond its physical qualities, tanzanite is often associated with insight, emotional balance, and personal transformation. It has long been connected to intuition and thoughtful clarity, making it a meaningful choice for custom jewelry tied to milestones or transitions. Whether selected for its rarity, its color, or its symbolism, tanzanite offers depth, individuality, and a sense of intention that feels especially fitting for a one-of-a-kind piece.

The experience was great thanks to Norrin. He was exceptional. We were about to walk out because one of the front desk employees told us no, but he came after us, took the time to help, and made everything work out. He went above and beyond, and we truly appreciate his assistance. He is the best!

It was definitely a pleasure working with Myah. I really hesitated to do this for someone else much less her 60th Wedding Anniversary. You know different taste or dissatisfaction about something, but thanks to Myah, everything worked out perfectly. And I know my sister so well. There was a great selection of bands with quality diamonds. Myah was so helpful in allowing me to take pictures for her. She and her husband live in Walterboro, SC. So it was very important for her to see the selection and make a decision. She is thrilled with the selection and looks forward to wearing it. It truly is a stunning ring! She has been wanting this type of ring for sometime so she decided their 60th was the appropriate time as it is known as the Diamond Anniversary. Myah, thank you so much for your help and patience. You are a Gem!!!
