Freshwater Pearls

Cultured freshwater pearls are pearls that are farmed and created using freshwater mussels. Quality of cultured freshwater pearls is evaluated through a grading system of a series of values, based on luster, shape, surface, color and matching. The process begins by choosing a suitable donor mussel and cutting a strip of tissue from the mantle is known as GRAFTING. This strip of tissue is then cut into 3mm squares. These squares are delivered to a technician who performs the operation. Unlike saltwater bead nucleation, this process is not considered difficult, and technicians need only minimum training to perform the operation. After the maximum numbers of grafts have been performed, the mussel is flipped, and the procedure is performed once again on the other valve of the shell.

Freshwater pearl harvests are typically bought while still in the shell. After harvest the pearls are delivered to a first-stage factory, which is responsible for cleaning and sorting the pearls by size and shape. After the pearls are treated, they are drilled and then polished with a mixture of cornmeal and wax.

Akoya Saltwater Pearls

If you’re looking for the classic set of pearls, look to Saltwater Akoya cultured pearls. These pearls were first to ever be cultured in the early 1900s. For the past 100 years, Akoya pearls have been synonymous with classic beauty and elegance. They are the roundest of all pearl varieties, and are known for their sharp luster and pink overtones.

The Akoya oyster is the smallest pearl-producing oyster used in pearl culture today, so Akoya pearls also tend to be small, ranging in size from just 2 mm to about 11 mm in size. The average pearl size is harvested at about 7.5mm in diameter.

Almost all pearls available in the market are cultured. Most natural pearls are odd-shaped because the irritants that caused the oyster to begin creating the pearl are not round. Beautifully round, lustrous natural pearls would cost many hundreds of thousands of dollars a strand.

South Sea Pearls

South Sea cultured pearls are exceptional quality pearls with a whitish, almost silver color. It is much larger than the average pearl. The smoothness and roundness of these pearls are exceptional. These are the rarest and extraordinary pearls you will find in jewelry.

South Sea pearls come from the white-lipped variety of the pinctada maxima oyster. This oyster is much larger than the oysters that produce Akoya and Freshwater pearls, so the pearl that it produces is much larger as well. Because of the rarity and sensitivity of this type of oyster, cultivation of these pearls is much more difficult, making them more expensive.

The average size of a South Sea pearl is 13 mm, with most harvests producing a range of sizes from 9 mm to 20 mm. The South Seas lie between the northern coast of Australia and the southern coast of China. These waters are the native habitat of a large oyster known as Pinctada maxima. This oyster grows up to 12 inches in diameter, and can be nucleated with a much larger bead than other saltwater oysters such as the Akoya.

Company Claims to Have Produced 5 Carat Synthetic Diamond

Featured

A Russian laboratory-grown diamond manufacturer, New Diamond Technology, is claiming it has produced a 5.11-ct diamond, the largest man-made, polished, near-colorless stone ever produced.

Synthetic-diamondAccording to the manufacturer, the unenhanced radiant-cut type ‘IIa’ diamond, produced by the high-pressure, high temperature method (HPHT) bears a K SI grade but hasn’t yet been sent to a lab.

This process is called Microwave Plasma Chemical Vapor Deposition, where carbon atoms are layered on top of an initial diamond ‘seed,’ fast-tracking a natural process lasting many millennia to a matter of months. And because these stones are lab-made, they’re good for the environment and are free of the ‘blood diamonds’ stigma that’s so tainted their traditionally-mined counterparts.

Diamond Experts familiar with diamond growing, say that it is an impressive achievement, but wondered whether it could be repeatable and also questioned what the stone would fetch commercially.

New Diamond Technology says it has a “new approach” that allows it to produce lab-grown gems with higher colors and clarity from its factories in Russia and Hong Kong. It said that it can produce gems ranging from 4 to 11 carats.

Company President Tamazi Khikhinashvili says that their diamonds are “more affordable” as compared to natural diamonds. He says the company has sold lab-grown gems to customers in Europe, Asia, and the United States.

It was a lucky day for Mr. Dean Filppula, an offshore steward from Shreveport, LA who visited the park during vacation after a rainstorm. He found “wedge-shaped light yellow stone about the size of an English pea” in the West Drain area of the park. He is calling this 2.01 Ct diamond after his mother’s initials as “Merf Diamond”.

Park interpreter Wayman Cox says Mr. Filppula was at right place at right time. It rained heavily before his visit, which washed loose soil from surface uncovering the large yellow gem. His store is very familiar to many visitors in past who have found diamonds.

Mr. Filppula found his 20th diamond, but it is largest one found so far in 2015. He is planning to sell the diamond.

Topaz, November’s primary birthstone, has one of the most confusing histories. The name is thought to have come from an island, Topazos, in the Red Sea, where both Topaz and Citrine were found. Since the two gems were alike in color they were often mixed up.
