Aquamarines shine over an extraordinarily beautiful range of mainly light blue colours

Aquamarine

Aquamarine is a relatively common gemstone, and is affordable in lighter colors. Deeper colors can command high prices. Some enormous transparent crystal masses of Aquamarine have been found, and exquisite gems weighing thousands of carats have been cut from them.

The light blue to blue-green color of Aquamarine may fade upon prolonged exposure to light, so it is especially important to purchase this gem from a reliable dealer. Aquamarine is a hard and durable gem, but it may develop internal cracks if banged hard.

Light blue Topaz is easily mistaken for Aquamarine. The colors of these two gems can be identical, and their physical properties are very similar. Topaz is generally less expensive, and some fraudulent dealers may sell their Topaz as Aquamarine.

Unlike Emerald, Aquamarine gems are often completely flawless. Aquamarines with visible flaws are rarely seen. The costs of producing synthetic Aquamarine are very high when compared to the relative abundance of this gem, so synthetic Aquamarine is generally not produced for the gemstone market.

Morganite is the stone of Divine Love

Morganite is the stone of Divine Love. This delicate yet powerful stone opens one to the frequency of the universal heart.

Alongside emerald and aquamarine, morganite is certainly the best known gemstone from the colourful group of the beryls. Women the world over love morganite for its fine pink tones which radiate charm, esprit and tenderness.

Moganite is a silicate mineral with the chemical formula SiO2 (silicon dioxide) that was discovered in 1984. It crystallises in the monoclinic crystal system. Moganite is considered a polymorph of quartz: it has the same chemical composition as quartz, but a different crystal structure.

In 1994, the International Mineralogical Association (IMA) had disapproved it as being a separate species because it was not clearly distinguishable from quartz. It has only recently been approved as a valid species by the CNMNC, the Commission on New Minerals, Nomenclature and Classification (part of the IMA).

This mineral is “virtually indistinguishable” from chalcedony which is made up of both moganite and quartz. It has been mainly found in dry locales such as Gran Canaria and Lake Magadi. It has been reported from a variety of locations in Europe, India and the United States. It was named for the municipality of Mogán on Gran Canaria. Physically, it has a hardness of about 6, a dull luster and appears gray in color but transparent.
