The natural unheated Burma rubies are a vivid red color, they are estimated to weigh 3.74 cts.

The double stems in the back are slightly curved so that they can both slide through fabric smoothly, and comfortable and easy to wear in the hair. The clip is also slightly curved so that it will hold any thickness of hair or fabric. The two pinstems squeeze together and each fit into its own holder making the barrettes quite comfortable.
