Tsavorite Alternate Birthstone for May A Variety of Grossular Garnet Tsavorite is a variety of green grossular garnet. It is one of the newest of the precious gemstones discovered in 1967. It occurs in shades of green ranging from spring-like pale green to intensely bluish green to deep forest green. Often compared to emerald, tsavorite is a superior choice in many ways. Tsavorite is not only more durable than emeralds, it is also more highly dispersive and refractive. Tsavorites are not treated with oils or resins as emeralds typically are.

Pearl Information

 Like the "four Cs" of diamond quality, shopping for pearls involves paying attention to a few important elements. High-quality pearl jewelry should consist of pearls of high luster and good surface quality, and the pearls should match in terms of color, shape and size. 

 Pearls come in a variety of different colors, from silvery white, to pinkish, to black. The consistency of the color affects the value; however, fashion trends and color demands also affect prices. 

 Luster is the shine and glow of the pearl, and a very important factor when it comes to judging beauty. The intensity of a pearl's luster is determined by its nacre, the layers of calcium carbonate that make up the pearl. The longer a pearl is left in the oyster, the thicker the nacre. The luster of a good quality pearl should be bright and not dull. 

 Pearls come in many shapes, depending on how they are formed within the mollusk. Because most people expect pearls to be round, and round pearls are very rare, they tend to be much more expensive than other shapes. 

 Surface quality refers to the topography of the pearl. Pearls are natural, so when you look at them closely, many tend to have imperfections such as tiny spots, bumps, or wrinkles. A pearl with fewer surface markings is more rare and valuable. 

 Pearl size refers to the pearl's diameter, which is measured in millimeters. Normally, the larger the pearl, the more rare it is and the more valuable. Keep in mind that pearl strands also have a length, which also affects price because of the number of pearls needed to create that particular necklace length.
