Calcite is a carbonate mineral and is the most stable form of calcium carbonate. With a hardness of only 3 on the Mohs scale, it can only be used in jewelry that won't be subject to knocks or scratches, such as earrings and pendants. Its hardness is similar to that of gems like amber, coral and chrysocolla. Though calcite is not an especially durable material, it does take an excellent polish. Many historical artifacts identified as alabaster are in fact made from calcite.
In what colors are Calcite Gemstones available?
Pure calcium carbonate is colorless, but calcite is often colored by various impurities, including iron, magnesium, manganese, zinc or cobalt. Thus you will find calcite in a range of colors including white, gray, yellow, green, red and blue.
I’ve made several purchases from Gemselect over the past few years since I began making jewelry. I have been always pleased with the website and quality of stones and shipping. I will keep coming back to shop here.
Everything was right there - The site provided the exact minerals I was looking for. The search for items filtered easily, with results showing pictures of exactly what I bought, at reasonable prices. It doesn't get any better than this. Well, the shipping charges could have been lower, but they weren't outrageous.
I decided recently to start a gemstone collection! I searched online for a reputable gem merchant and found gem select! Their selection is gorgeous and I'm excited to receive my first package! Checkout was a breeze!
For gem web photos - - it would help some inexperienced gem buyers like me to show the gem next to a common object such as a US dime for example. Two of the blue star sapphires I purchased are not suited for ring mounting - - way too small. Now I know to purchase a caret weight of about 12 to 20 carets.
Completely would recommend this company to any gem collector, jewelry store, or someone looking for a gemstone to repair their jewelry. There is an abundance of choices at great prices! If you dona't see what you need exactly the customer service department will go above and beyond to meet your needs. Shipping is very reasonable! The gemstones always arrive well before the expected arrival date. This company has very high standards of meeting their customers needs! They are the number 1 company I go to when looking for any gemstone. They are also very detailed in their descriptions so there is no confusion at all as what you are purchasing! Highly recommended!!!!
