The ruby is one of the most significant colored stones. This red gemstone is a variety of  the  mineral corundum (aluminium oxide). The red color is caused mainly by the presence of the element chromium. Its name is derived from ruber, Latin for red.

The demand for rubies is as great today as it was hundreds of years ago. Rubies can command the highest per-carat price of all colored stones. The ruby is also popular because of its hardness (9 on Mohr Scale) that makes it durable enough to be used in frequently worn jewelry. The presence of silk (a network of fine, included rutile needles, intersecting at 60 degree angles commonly found in natural rubies) or inclusions is an indication that the gem has not been treated and adds to its value.

Red indicates our most intense emotions like love and passion and that make rubies ideal romantic gifts.  Rubies appear as accent stones in engagement rings more often than any other colored gems and have traditionally been a symbol of commitment and a promise of the heart.  Rubies symbolize success, devotion and integrity. Ruby is the birthstone for July. The ruby is also the gemstone for commemorating a 40th wedding anniversary.
