Blue Calcite Crystal
Authentic natural minerals, thoughtfully sourced and individually photographed.
Blue Calcite is a calcium carbonate mineral with the formula CaCO₃, crystallizing in the trigonal system. Its soft, icy blue color — ranging from pale sky blue to a deeper steel-blue — is attributed to trace amounts of various impurities during formation. Like all calcite varieties, blue calcite has a Mohs hardness of 3, making it relatively soft and best suited for display rather than heavy wear. The most prolific sources of blue calcite are Mexico, Madagascar, and South Africa.
Blue calcite shares the remarkable optical properties of the calcite family, including strong double refraction and a perfect rhombohedral cleavage that produces clean, geometric fracture surfaces. Among collectors, blue calcite is valued for its calming color, its accessibility as an affordable mineral, and its availability in large, polished display formats. Raw blue calcite masses from Mexico are particularly popular for their size and vivid coloring. The stone also fluoresces under ultraviolet light, often producing a bright blue or white glow — making it a favorite among fluorescent mineral collectors.
Our blue calcite collection includes:
- Raw masses and specimens
- Polished spheres, hearts, and freeforms
- Tumbled stones and palm stones
- Bracelets and jewelry

LOVE IT. Colors are absolutely beautiful, the fit is perfect, and I'm so glad to say that I'm happy with the size of the crystals - I was afraid I wouldn't like to smaller size as I'm used to 8 mm.
This necklace is beautiful. They were out of it, but I love the substitution. All their jewelry is beautiful.
Love it so much! Looks and feels wonderful.
It's incredibly beautiful. Love that different aspects of it are highlighted in different lighting - in a bright setting you see a million tiny quartz on top that you would never know were there in the lower lighting setting. My favorite is the amazing combination of sections that sparkle and sections that are smooth and gleaming. Looks and feels wonderful. Perfectly packed too.
Love the scent, it's wonderful, and thank goodness for it as it gets rid of the odors that come in from outside, and is healthy because of the materials. Looks nice too.
Smells dreamy, is super relaxing, and is healthy because of the materials. Looks nice too.
Perfect and lovely way to appreciate these beautiful crystals - nature's jewels - and also have a place to store rings or bracelets.
