Sometimes it is not the design that makes a piece of jewelry unique, but the material it is made from. Most gemstone jewelry uses material that can be found world-wide or at least in several different locations. Thus many times the same piece or variety of Agate or Jasper goes by various names. Other gemstones that are found world-wide, for instance Turquoise, is known by the same name eveywhere. And then there are a few gemstones that are unique to a single location. .
This necklace is such a design, The pear shapped Nevada Lapis pendant hanging from a string of Freshwater Pearls and Crystals, comes from a single location. The necklace is then highlighted by round and tube silver plated beads with a silvefr toggle clasp. French hook earrings with Freshwater Pearls and silver beads complete the set.

The second design below uses another Nevada Lapis oval pendant which has been wire-wrapped and hangs from a necklace of Opalite beads which are also used in the French Hook earrings.

Nevada Lapis is a interesting gemstone in the skarn family (A lime-bearing silicate derived from nearly pure limestone and dolomite with the introduction of large amounts of silicon, aluminum, iron, and magnesium). One dealer claims it is form of Chalcedony (a cryptocrysalline form of silica, composed of very fine intergrowths of the minerals Quartz and Morganite) from the Orient, varying in shades from pastel pink, green, beige, gray, yellow, and white. It other words, Nevada Lapis looks like an agate but in pastels. This dealer also says that the name Nevada Lapis is a misnomer, because it is neither from Nevada nor in the Lapis family of stones. It is likene to Unakite, but with different color scheme.

Then there is a report from a geologist that says the scientific name for Navada Lapis is “Thulite-Diopside Skarn”. It is a rock composed of at least ten distinct minerals including: Thulite, Diopside, Clinozoisite), Microcline, Sericite, Titanite, Epidote, Plagioclase Feldspar, Scapolite, Actinolite and Quartz. The pink color is due to the presence of Thulite and Clinozoisite, the green is due to Diopside, and the cream color is mostly due to the presence of Microcline and Scapolite. Navada Lapis is a skarn of hydrothermal origin, having been formed from a granite which is 171 million years old. Because of the hydrothermal origin, all of the minerals forming this "gem quality skarn" are silica rich, which gives Navada Lapis its hardness and ability to take a polish. Previously skarn had never before been found to occur as a gemstone. The general character of the Navada Lapis is very similar to that of the Yerington Batholith rocks composed from diorite in granite. This formation is only known to exist in the east side of the Pine Nut Range. These rocks are associated with the giant porphyry copper deposit in northwest Nevada near Yerington in Storey County, close to Douglas, Nevada. This type of skarn is known from various places around the world, especially in the Orient, but nowhere else is it found to occur as gem-quality material and as colorful as the Nevada Lapis. The brightness of the pink Thulite and green Diopside in combination is unique in the world.

Freshwater Pearls, abreviated FWP, are a kind of pearl that comes from freshwater mussels. They have been produced prodominently in Japan and the United States on a limited scale, but are now almost exclusive to China. The U.S. Federal Trade Commission requires that all freshwater pearls be referred to as "freshwater cultured pearls" in commerce settings.
.
Opalite is a stone mined in Utah that comes in varying shades of purple, lavender and creamy white with swirls of yellowish-brown and pink. Opalite is also referred to as Tiffany Stone. Opalite is also a trade name for synthetic opalized glass and various opal simulants. The name is also many times used to promote impure varieties of variously colored common opals.
