Sample-certificate Copy of Gems[/caption]Details:
Among the gemstones that display special optical phenomena, cat's eye gems are particularly interesting, in part because the effect is found in so many different gem varieties. The technical term for the cat's eye effect is chatoyancy, derived from the French for eye of the cat ("oeil de chat").
The chatoyant effect resembles, appropriately enough, the slit eye of a cat. The effect is caused by the reflection of light by parallel fibers, needles or channels in the gemstone. Usually the gemstone needs to be cut en cabochon with the base parallel to the fibers for this effect to be displayed. When the gem is rotated, the cat's eye appears to glide over the surface. The chatoyant effect is similar to asterism (the star effect), except there is one straight ray instead of four or six. Occasionally a cat's eye with two parallel rays can be seen.
Cat’s Eye gets its unique look due to the presence of fibrous mineral inclusions. The fibers in a Cat’s Eye form tubes that are parallel to one another deep within the quartz stone. These fibers are not that pronounced when in a square or rectangular form, however when in a sphere or oval shape, the fibers are more pronounced and extremely fascinating to look at.
The Cat’s Eye comes in many different colors such as gray, grayish green, yellow, red, blue, brown, black and white. The luster of the Cat’s Eye gives it a chatoyant or vitreous look and it is usually opaque or translucent in transparency.
The Cat’s Eye is usually rounded, oval or spherish, and quite attractive on many types of ornamental jewelry.

Emerald - 7.9 carat , Rs 18500[/caption]Information about Emerald
Refractive Index: 1.566 - 1.602
Specific Gravity: 2.67 - 2.78
Has hexagonal crystals. Base of such crystals is usually flat.
Cleavage: 3,1 - basal
Emerald is a gemstone, and a variety of the mineral beryl (Be3Al2(SiO3)6) colored green by trace amounts of chromium and sometimes vanadium. Pure Beryl is colourless.
Green color due to: With less than one percent chromium (or vanadium).
The beryl family includes pale blue aquamarines, pink morganites, golden heliodors, red beryls, and pale green beryls. Beryls are silicates which comprise the largest class of minerals, yet Emeralds are only a very small fraction of this class.
Beryl has a hardness of 7.5–8 on the 10-point Mohs scale of mineral hardness.
Most emeralds are highly included (some form of impurities), so their toughness (resistance to breakage) is classified as generally poor.
Colour
Color is divided into three components: hue, saturation and tone.
Emeralds occur in hues ranging from yellow-green to blue-green, with the primary hue necessarily being green. Yellow and blue are the normal secondary hues found in emeralds. Only gems that are medium to dark in tone are considered emerald; light-toned gems are known instead by the species name green beryl. The finest emerald are approximately 75% tone on a scale where 0% tone would be colorless and 100% would be opaque black.
In addition, a fine stone should be well saturated; the hue of an emerald should be bright (vivid). Gray is the normal saturation modifier or mask found in emerald; a grayish-green hue is a dull green hue.
Emeralds are green by definition (the name is derived from the Greek word "smaragdus", meaning green). Emeralds are the green variety of beryl, a mineral which comes in many other colors that are sometimes also used as gems, such as blue aquamarine, yellow heliodor, pink morganite, red red beryl or bixbite, not to be confused with bixbyite, and colorless goshenite.
Clarity
Emerald tends to have numerous inclusions (visible impurities or invisible under eye) and surface breaking fissures. Unlike diamond, where 10× magnification, is used to grade clarity, emerald is graded by eye. Thus, if an emerald has no visible inclusions to the eye (assuming normal visual acuity) it is considered flawless.
Stones that lack surface breaking fissures are extremely rare and therefore almost all emeralds are treated ("oiled") to enhance the apparent clarity. The inclusions and fissures within an emerald are sometime described as 'the garden', because of their mossy appearance.These imperfections within the stone are unique to each emerald and can be used to identify a particular stone.
Eye-clean stones of a vivid primary green hue with no more than 15% of any secondary hue or combination (either blue or yellow) of a medium-dark tone command the highest prices.This relative crystal non-uniformity makes emeralds more likely than other gemstones to be cut into cabochons (A cabochon, from the Middle French caboche (head), is a gemstone which has been shaped and polished as opposed to faceted), rather than faceted shapes.
Faceted Emeralds are most commonly given the Oval cut, or the signature Emerald cut, a rectangular cut with facets around the top edge.
Treatments
Most emeralds are oiled in order to fill in surface reaching cracks, improving their clarity and stability. Cedar oil, having a similar refractive index, is often used in this generally accepted practice. Other liquids, including synthetic oils and polymers with refractive indexes close to that of emerald such as Opticon, are also used.
The use of oil is traditional and largely accepted by the gem trade, although oil treated emeralds are worth much less than un-treated emeralds of similar quality. Other treatments, for example the use of green-tinted oil, are not acceptable in the trade.
Gems are graded on a four step scale; none, minor, moderate and highly enhanced. Note that these categories reflect levels of enhancement, not clarity. A gem graded none on the enhancement scale may still exhibit visible inclusions.
Given that the vast majority of all emeralds are treated as described above, and the fact that two stones that appear visually similar may actually be quite far apart in treatment level and therefore in value, a consumer considering a purchase of an expensive emerald is well advised to insist upon a treatment report from a reputable gemological laboratory. All other factors being equal, a high quality emerald with moderate enhancement should cost severely less than an identical stone graded none.

Pukhraj 9.5 carat Rs 85,000[/caption]Cost: Rs 85,000Information About Sapphire:
Sapphire has derived from the word which means "hard stone". In some other languages it means gem. Sapphire belongs to the Corundum family.
It is found in different colors from yellow to blue, green, orange, pink, purple etc.
Structure of Sapphire:
It has a trigonal structure
It has no cleavage planes (Cleavage planes is the tendency of crystalline materials to split along definite crystallographic structural planes For more details about clevage plane click here).
It has conchoidal fracture. Conchoidal fracture describes the way that brittle materials break when they do not follow any natural planes of separation. Exhibits rhombohedral and basal parting.
Commonly forms hexagonal barrel-shaped prisms that taper at both ends or as thin tabular hexagonal plates.
Specific gravity: 3.95 - 4.10
Chemical Composition: Aluminium Oxide. Sapphire is the crystalline form of Aluminium oxide.
Refractive Index: 1.76 - 1.77
Hardness level : 9 on Mho scale
Double refraction: 0.008
Inclusions / Impurities
The various impurities are known as inclusions. Inclusions can moisture, feather, silk fibre or any other substance.
Colour:
Pure corundum is colourless and clear if transparent or pale white if opaque. This mineral also has low dispersion so the value of the stones comes not from fire generated (as in diamond), but rather from the intensity of colours seen.
The vivid colours of corundum gem varieties, such as ruby and sapphire, arise primarily from elemental substitution in the Al site by transition metal elements. The most common cations to substitute are Fe+2, Fe+3, Ti+4, Cr+3, and V+3.
A continuum of colour saturation exists between pink sapphire and ruby that is correlated with trace amounts of Cr. There is no official cutoff for the amount of Cr needed for ruby, but usually rubies will have up to ~1 wt% of Cr2O3.
When Cr is introduced into corundum it makes the mineral fluorescent under UV light. This means that UV energy from normal light is accepted into the crystal and then re-emitted at a lower energy level - conveniently in the red region, thus amplifying the intensity of red in ruby under daylight conditions. However, if any iron is present it will usually absorb the red fluorescence from UV light. Thus, the finest rubies are those that have little to no iron in their crystal structure.
Blue sapphires are generated primarily from pairs of Fe+2 and Ti+4 substituting into the crystal structure for Al+3. The process of intervalence charge transfer (essentially continual swapping of electrons, bouncing back and forth) occurs between the Fe and Ti and all colours except blue are absorbed. So that generates the beautiful blues in sapphires.
Other colours are generated from a combination of these elements, as well as other minor cations and defects in the crystals. Also, a single corundum gemstone can be multi-coloured from different concentrations of metals in different parts of the crystal - this is called zoning.
Some sapphires also show an optical characteristic called asterism, which is most commonly seen as a six or twelve pointed star. These "arms" of the star are generated from oriented inclusions of long and skinny minerals (almost always the mineral rutile, a titanium oxide, TiO2). Specimens found with these inclusions are often cut and polished in a rounded and polished cabochon style to emphasize the nature of this optical effect.
Sources of Sapphire:
At present most common sources are Lanka, Burma,Thailand, Australia, Madagascar, Tanzania, Zambia , Brazil.
As per mineralogy Ruby and Sapphire are scientifically the same mineral but just different colors. Ruby is the red variety, and Sapphire is the variety that encompasses all other colors, although the most popular and valued color of Sapphire is blue. Sapphire is also only used to describe the gem variety, otherwise it is simply called Corundum. For all practical purposes, it is the hardest mineral after Diamond, making it the second hardest mineral. It is also unaffected by acids and most environments.
Common Treatments for Corundum
At any gem corundum mine, most of the material found is not of gem quality. As a consequence, much effort has been directed to improving the quality of mined stones ever since mining of corundum began. Almost all (~99%) sapphires and rubies are heat treated to change colours, intensify them, and increase clarity.The solid inclusions that detract from a stone's clarity are usually comprised of elements that, coincidently, can be incorporated into corundum's crystal structure. These inclusions are commonly rutile (TiO2), spinel (ideally MgAl2O4, but often "impure"), and iron titanium oxides such as ilmenite (FeTiO3). Corundum's melting point (~2000 °C) is higher than most of its common inclusions. Thus, heating allows the solid inclusions to resorb or "melt" back into the corundum's crystal structure without melting the corundum.
Heating improves clarity by "removing" the opaque inclusions, but also by allowing chromophore-type elements, such as Ti and Fe, to become part of the corundum crystal and help colour the stone. Under the right conditions, Fe can be chemically "persuaded" to acquire a charge of either +2 or +3 which will also affect the resulting colour. Fluid inclusions and fracture-type inclusions won't add to a stone during heat treatment, but these features can be annealed or healed to make them "disappear". Consequently, the clarity of the treated stone can increase dramatically.
Corundum also commonly undergoes diffusion treatment where an element not associated with the crystal is forced into the structure via heat, pressure, and chemical gradients. This allows the "treater" or chemist, to impart a variety of colours to the original crystal. Diffusion is most commonly used to change colourless sapphires into Padparadscha sapphires with the diffusion of beryllium (Be).
Treatment to corundum is typically done to rough stones that have not yet been cut since exposure to the high heat can also cause new fractures to form. Otherwise, a faceted stone could lose considerable value if it broke during the heat treatment process.

- 1 tola = 12 masha or 11.67 gram
- 1 masha = 8 ratti or 0.97 gram
- 1 tank = 4 mashas or 3.88 gram
- 1 Ratti = 0.91 Carat
- 8 Ratti = 1 Gram
- 1 carat = 1.0989 ratti
