Synthetic Sapphire and, particularly, Synthetic Ruby materials are quickly becoming the jewels of the industry.

For companies who are producing a specific product, these materials make an immediate statement about quality. For instance, watches often feature, on their face, that all movements are fully jeweled. Furthermore, many ball point companies exclusively use ruby ball tips which offer a smoother and finer writing quality.
