Rutile topaz, and its applications
Rutile is a mineral that is mostly composed of titanium dioxide
Rutile can be found in other minerals, one of which is quartz
Low amounts of needles in the form of needles give three star marks on sapphires and pomegranates, which are called star rubies and star pomegranates
This means that this type of jewelry on its surface reflects a star sign
Rutile is an immaturity that increases the value of the gemstone instead of reducing it because it has an attractive and unusual appearance
Some call it the hair of Venus, and some consider it to look like a mat, and some compare it to golden beads or yellowish-brown needles
Because the immaturity of rutile topaz is very similar to that of rutile quartz, it is assumed that they are made of the same material
Therefore, rutile topaz is a term used for brownish-yellow topazes with immaturity
Thus, in 1987, the American Institute of Gemology (GIA) examined rutile topaz rocks under a microscope
Given the structure of the inconsistencies, the GIA concluded that they were not rutile but limonite stains that filled in the voids
Limonite is a yellow or brown iron ore that was originally used as a dye
One of the famous products of limonite is yellow iron ore in Cyprus
The results show that it is better to call rutile topaz limonite topaz, but the name rutile topaz fits in, so it is known by the same name
Identification of rutile topaz
Rutile topaz is similar to rutile quartz, but rutile topaz can be distinguished by its strength and hardness
Topaz has a resistance of 8Mohs while it is 7 for quartz
Also, quartz has no gaps while topaz has a complete gap
Rutile quartz usually has more patterns than rutile topaz. Rutile topaz defects are more common
Rutile Topaz, Origin and Sources
Topaz reservoirs have been found in Brazil, Afghanistan, Australia, Myanmar, China, Germany, Japan, Madagascar, Mexico, Namibia, Nigeria, Pakistan, Russia, Zimbabwe, Sri Lanka, Ukraine and the United States
The natural color blue topaz is found in Northern Ireland and England
Numerous crystals of topaz have been found in Brazil and Ukraine
Rutile topaz is usually colorless and has golden discoloration
These defects can be scattered and occupy one or two parts or be close to each other
Rutile topaz incontinence varies from golden yellow to yellowish brown
In very rare cases, band-shaped defects can be silver or even rainbow
The reason for this color is limonite combined with other minerals
Because topaz has other colors such as orange, pink, blue, green and even purple, rutile topaz is available in the same colors
However it is mostly colorless
Transparency and radiance of Rutile Topaz
Rutile topaz varies from clear to opaque. Topaz has low transparency with low inclusions, so topazes can be examined with the naked eye
However, in the case of rutile topaz, infertility is valuable
Topaz is very popular because of the brightness and transparency of its glass
Cut and shape of topaz rutile
Topaz is a very widely used substance
So there are different shapes of it like square, circle, octagon, pear shape, oval, heart and so on
The jeweler must carefully cut the rutile topaz so that the imperfections of the limonite inside it are clearly visible, because more or less of them depends on the viewer’s point of view
Topaz resistance makes it resistant to scratches
However, care must be taken to create gaps that increase the refraction of light
Preparation and manufacture of Rutile Topaz
While topaz colors can be changed, colorless topaz is an example of naturally occurring as a result of limonite anomalies
Therefore, rutile topaz with its natural color can not be made or optimized
Features of Rutile Topaz gemology
Chemical formula: Al2SiO4 (F, OH) 2Fluor containing aluminum silicate
Crystalline structure: rhombus straight, prism with polygonal and octagonal poles in sections

Transparency: Transparent and opaque
Double refraction or double-sided failure: 0.008 to 0.016
Luminosity: Glass
Night exposure: Under long UV wavelengths, white and blue turn pale yellow or greenish
Brown, pink and yellow can have a strong orange-yellow glow, red has a weak yellow-brown glow
Rutile Topaz: Similar Gemstones
Topaz is chemically related to sillimanite, andalocytes, canonite, cyanite and molite
Rutile topaz is similar to rutile quartz, but rutile quartz has a different composition with limonite anomalies, which is slightly softer and has a Mohs resistance of 7
Rutile topaz is more valuable than rutile quartz, so the difference between the two should be noted
Limonite aneurysms can also be found in other gemstones, such as Yemeni quartz, which is golden in color and contains needle grains
Rutile Topaz Gemstone and Jewelry Design Ideas
Rutile topaz can be used to make all kinds of jewelry due to its high versatility
This stone is a good choice for rings, necklaces, bracelets and brooches and can come in any shape
Like diamonds, rutile topaz should not be hit hard. Because it is crushed with one blow
Rutile topaz has high hardness and is scratch resistant
It must be carefully cut so that the limestone imperfections show their best appearance
Tip: Buy colored gemstones according to their size, not carat weight
Colored stones vary in size and weight
Some stones are larger and some are smaller in weight than diamonds
Maintenance and cleaning of Rutile Topaz gemstone
Like rutile diamond, topaz is very slippery, meaning it can be crushed with just one blow
Therefore, you must be very careful when turning and use the appropriate cutting edges
The hardness of rutile topaz makes it durable and does not scratch quickly
To clean it, use a soft cloth and soap and water and then thoroughly clean the soaps
Like many gemstones, chemical and steam cleaners are not a good choice
Take it off before exercising or doing physical activity
Rutile topaz should be kept separate from other jewelry to avoid scratches
It is better to put it in a wrapped cloth and inside a jewelry box
