Natural pearls are rare, extremely rare and would be very expensive. Today, nearly all pearls sold are cultured, they can be cultivated in sea water or fresh water.Sea water pearls, perfectly round, cream color and lustrous, are higly prized. Mostly found in the seas of Japan.
Consider the famous Japonese Akoya Pearl, grown inside the oyster in cold water over a period of 8 to 24 months. These when finally harvested will become a stunning strand of pearl necklace or earrings.
Less perfect in shape are the fresh water pearls, they won't have the same luster either and are farless expensive. They are on the other hand very durable and perfect choice in designing pearl jewelry.
Sea water pearl is bead nucleated,and the bead nuclei helps as guide and forms a perfectly round pearl. Fresh water pearls is created by introducing a tiny piece of mantle tissue from a mussel,injecting it into the mollusk and returned to its natural habitat.
Characteristics of the pearl with which it is graded are: luster, surface clarity, nacre thickness,color, shape, and size. Pearls are graded against each other, for example South sea pearls are not graded against Akoya pearls.
Luster: is often spoken of when describing pearls, luster is the deep inner glow, the most important factor in evaluating a pearl's quality. Experts consider luster the heart and soul of a pearl.
Surface: refers to the abundance or absence of physical blemishes. The fewer the better, and more expensive.
Color: From silvery white to black and a rainbow of colors inbetween. Color is a personal preference. Color rarely affects the price.
Shape: simply put, the rounderand more spherical, symmetrical the pearl, the more valuable.
Size: measured by their diameter in millimeters. It can as small as one mmandaslarge as twenty mm.

There was a time when every green gemstone was considered an Emerald. You say the word emerald and visions of intense vivid greens come to flash before our mind's eye. It is a stone that has been used to make jewelry for as long as history. From the Egyptians to the Romans to modern day, Emerald much as many other gemstones, has great value and significance. From the ancient belief that it brings fertility and eternal youth to today's notion of its great exotic nature.
At Jewels Quest, we carry a few pieces of Emerald jewelry and often disclose much about it to our customers who desire to buy an Emerald. It is a beautiful stone and knowing and understanding fully the features of this gemstone before you buy it leaves customers better equipped to make their decision before buying it.
Let's begin with the 4 c's of Emerald, these are the same as diamonds, cut, clarity, color and carat weight. The difference is the importance of the order. In diamonds, you'd be more concerned with the clarity grade while with emeralds we look at color which is the most important aspect to consider with emeralds, while the carat weight will be the least important.
Tip#1: The darker the color, the more valuable: It would have to be a dark blue green while still brilliant and translucent, simply dark green opaque stones isn't enough to be considred valuable, these can be quite cheaper in fact.
Tip#2: Inclusions in the emerald are what cause the beautiful green color: Remember that point, and don't be surprised at how highly included these precious stones are. It is also the reason why the emerald rough must be cut away so much. This weight loss is the main reason of their high cost.
Tip#2: Symmetrical and uniform facets providing maximum color and brilliance are an Emerald's ideal cut: If the cut is too shallow, light will be lost at the bottom of the stone and the emerald will not have maximum brilliance. If the cut is too deep, the light will escape out of the sides and the emerald will appear dark.
Caution when cleaning your Emerald jewelry: Clean your emerald with a soft, dry cloth. Oil is used during the stone treatment, therfore you should never clean an emerald with an ultrasonic cleaner because this oil could be removed or damaged. In addition, do not clean emerald in hot soapy water since it too can remove this oil. Avoid sudden temperature changes as emeralds lose their color when strongly heated.
