HOW TO CHOOSE

A key point in choosing a ruby is how well its quality matches the conception of the jewelry it is set in. The overall class of a ring with a Mong Hsu ruby set as the main stone invariably will be judged by the quality of the ruby, so an impressive gem-quality ruby or a carefully selected jewelry-quality ruby is recommended. In a style that uses a number of small gemstones, it is important that they match each other in terms of color tone and quality level.

As with any other gemstone, Mong Hsu rubies with a slightly lighter tone (about level 4) will reveal their beauty even when worn under weak lighting, so it is wise to choose a beautiful stone that is a bit light in tone over a darker stone.

The value of a one-carat-size, heat-treated Mong Hsu ruby of jewelry quality is approximately US $2,000 for the stone alone. (2001)
