Whether you are purchasing it as a gift
Any gemstone can be judged by cut, colour, clarity and carat.
Cut (and Shape)
Don't know what shape to get? The same shapes that are used for diamonds
can be found in other gemstones as well. Non-diamond gemstones have another shape available to them: the cabochon .A cabochon is a stone that has been polished but not cut. (That is, it doesn't have facets.) Cabochons are frequently domed stones. They often have flat backs set in rings or pendants .Although usually used for opaque stones, a few of the translucent stones, especially members of the quartz family and amber, also look good as cabochons. Star sapphires must be polished as cabochons to make the asterism visible, and amber is often polished to show off any interesting inclusions.
Colour is another value-inducing factor of a gemstone
.It is not the colour itself that matters, but the quality of the colour, including hue (colour), tone (lightness or darkness), and saturation (purity).To accurately judge the hue of a gemstone, look at it in bright light against both black and white backgrounds. You want the gemstone to be even in hue without any cloudiness or brown or grey spots. The centre should not look pale or washed out in any way. Ideally, a quality gem will be darker rather than lighter, but it should not be darker than medium dark. Sometimes gemstone manufacturers use heat treatment to intensify or change the colour of a gemstone, but this will decrease its value and cost.
As with diamonds, clarity is measured on a scale of VVS1, VVS2, VS1, VS2, SI1, SI2, I1, I2, I3, with VVS1 being flawless and I3 being badly flawed. Spots, cracks, and inclusions (flaws) are all negative factors of clarity. Clarity and transparency is often fixed by oils, resins, and chemicals used by gemstone manufacturers. Some gemstones are more likely to possess and show flaws than others.
Most gemstone weights are measured in carats. Keep in mind that because of the different densities of different stones, a carat of one might not be the same diameter as the carat of another. When comparing many stones, use the length and width or the diameter (depending on the shape) to figure out the size of the stone.
Pearls are the ultimate classy necklace. Less showy and more feminine than diamonds, pearls make any woman more ladylike. Dress them up with a little black dress
The solitaire is another timeless classic. This look works with anything from a v-neck jumper
Whether it's a thick link bracelet
A women's watch isn't strictly for function, it can be a great piece of jewellery as well. If you are buying a watch for the professional woman, consider a nice silver
Whether a woman is high maintenance or no-fuss about her jewellery, a nice set of post earrings is great to have on hand. These can be dressed up or down, and come in simple styles such as cubic zirconia
Buying and giving jewellery as a gift can be a gruelling process. Women have different tastes, and knowing how to recognize quality is also an important skill that many people lack. Here are some tips on how to make the best purchase:
You might think that a rock is a rock is a rock, and you can basically clean all of your jewellery the same way--but you'd be wrong. Proper care for a given piece depends on the materials and the style of the piece. Use care! Methods that get great results for one kind of gem may be devastating to another. If you are uncertain about how to clean a particular piece of jewellery, ask the jeweller or have it professionally cleaned. Isn't your good jewellery worth it?
One more tip on general gemstone care: don't be fooled by the statement, "Diamonds are the hardest substance known to man." The hardness of a mineral refers to its ability to scratch or be scratched by other materials. Diamonds can't be scratched; however, they can be chipped, cracked, or even shattered by a sudden impact. This is true of any hard stone, but diamonds are particularly vulnerable to negligence because they are thought of as indestructible. Use care when handling and cleaning your jewellery and avoid dropping it or banging it on a surface.
