Birthstone for July
The Ruby gemstone is one of the most coveted gemstones. The rich red of a Ruby gemstone comes from trace amounts of the element chromium mixed with a variety of the mineral corundum. Some Rubies get their deep read from being heat treated, this makes the gemstone softer and less durable. Rubies can command the highest per-carat price of any colored stone. This makes ruby one of the most important gems in the colored stone market. In its purest form, the mineral corundum is colorless. Trace elements that become part of the mineral’s crystal structure cause variations in its color. Chromium is the trace element that causes ruby’s red color. The Ruby is the birthstone for July.
