Stellar Jewelry: Shop by Material Type

Diamonds
The mineral diamond is a crystalline form of carbon. It is one of the most known and most useful of more than 3,000 known minerals. Diamonds are renowned for their superlative physical qualities, especially their hardness […] and their high dispersion of light. more...

The standard quality diamonds we use at Stellar Jewelry are all genuine diamonds SI to VS clarity and GHI color unless noted otherwise.

Upon customer request, the diamond clarity may be substituted for I (Included), VVS (Very Very Slightly Included), IF (Internally Flawless), or Fl (Flawless) diamonds. The 4 C’s of a diamond

Moissanite
Moissanite is a silicon carbide similar to diamond in several ways. Naturally occurring moissanite is extremely rare within the Earth. In 1998, C3, Inc. (Charles and Colvard) introduced gem-quality synthetic silicon carbide onto the market under the name "moissanite," marketing it as a lower-cost alternative to diamond. more…

Even though moissanite is a lower-cost alternative to diamond, there are three main factors preventing moissanite from dethroning cubic zirconia as queen of diamond simulants: dispersion, color, and cost.

Dispersion
Moissanite has a dispersive power nearly 2.5 times greater than diamond (0.104 vs. 0.044), which means the 'fire' of moissanite may be viewed as too excessive.

Color
All moissanites have been plagued by a muddy tinge, usually green or gray. Lacking the brilliant whiteness of cubic zirconia, most moissanites would grade within the I-K color range of diamond.

Cost
Due to its relatively expensive manufacturing process, moissanite is much more expensive than cubic zirconia.

Cubic Zirconium (CZ), Cubic Zirconia [pl.]
Cubic Zirconia (or CZ) is zirconium oxide (ZrO2), a mineral that is extremely rare in nature but is widely synthesized for use as a diamond simulant. The synthesized material is hard, optically flawless and usually colorless, but may be made in a variety of different colors. more…

When Cubic Zirconia (CZ) is used, it will be clearly mentioned in our product description.

10K, 14K, and 18K | Yellow Gold, White Gold, Two-Tone Gold, or Tri-color Gold
Karat (K) is a measure of the purity of gold. One Karat is one twenty-fourth purity by weight. Therefore 24-Karat gold is pure gold, 12-Karat gold is 50% purity, etc. more…

Colors of Gold
The metal added to gold to make an alloy is varied to control the color and mechanical properties of the alloy. Frequently added metals are Silver, Copper, Palladium, Nickel and seldom small quantities of Aluminum, Zinc, Iron or Manganese. The most common colors of gold are yellow, red and white. Rarely used are the green, purple and blue gold, some of which are obtained by creating a special oxide surface layer. For further reading, visit the World gold association.

Yellow Gold
The natural color of gold is bright yellow. The base system used for making yellow gold lower than 24K is Gold-Silver-Copper. Different ratios of Silver and Copper are used to determine the color tendency towards red or greenish. For example, one of the common European standards for 18K yellow gold is 75% gold and equal shares of Silver and Copper, 12.5% each.

Red Gold
A gold alloy with high Copper content. The higher the Copper concentration, the more red the gold alloy becomes.

White Gold
When metals with typical white brightness are added to gold, the result is an alloy with a white color tendency. Base system compositions used for obtaining white gold are the Gold-Palladium-Silver and the Gold-Copper-Nickel-Zinc systems. Nickel is a metal capable of penetrating the blood circulation through the skin and causing severe allergic symptoms. If you decide on wearing white-gold jewelry, it is highly recommended that you verify that the white gold is Nickel-free.

Nickel content in Stellar Jewelry 14KW Gold: 12.73%
Nickel content in Stellar Jewelry 18KW Gold: 10%
Nickel content in Stellar Jewelry 14KY Gold: 0%
Nickel content in Stellar Jewelry 18KY Gold: 0%
Nickel content in Stellar Jewelry 18K Palladium: 0%

Gold plated
A term often used for a base metal plated with a fine layer of Gold. The plating layer is typically very thin with a thickness of several tens of microns (1 micron = 0.001 millimeter). When purchasing gold-plated jewelry, one has to take into account that the gold layer might be scratched or pealed off with time.

Gold filled
The name speaks for itself: Goldfilled is gold, filled with base metal. The result material is base metal in the metal interior and gold on the exterior. In contrast to gold plating, the gold in goldfilled metal is a substantial part of the metal, typically 5%. This is a relatively thick gold layer that wouldn't scratch or get off under normal use and care of goldfilled jewelry. We use 14K Goldfilled, namely 14K Gold forming the external 5% of the metal. Goldfilled jewelry is an excellent solution for those of us who like the look of Gold but not its price.

14K. Unless noted otherwise, Stellar Jewelry’s quoted prices are for 14 Karat (14K) gold. In most instances, our prices for 14K white gold are close to those of 14K yellow gold. Should the price be different, it will be clearly noted in the product description or shopping cart options.

18K. Almost all items may be upgraded to 18 Karat (18K) yellow or white gold. Please contact Us for a price quote.

10K. 10K gold is also available upon customer request.

Many items are also available in two-tone gold or Tri-color gold. 1 DWT is equivalent to 1.555 grams of gold.

Pearl
Pearls are an organic gem, created when an oyster covers a foreign object with beautiful layers of nacre. Today pearls are cultured by man: shell beads are placed inside an oyster and the oyster is returned to the water. When the pearls are later harvested, the oyster has covered the bead with layers of nacre. more...

Sterling Silver and 999 Silver
Sterling Silver is a soft white lustrous transition metal that has the highest electrical and thermal conductivity of any metal and occurs in minerals and in free form. This metal is used in coins, jewelry, tableware, and photography. more...

Sterling Silver, or 925 Silver is the standard used in the jewelry industry. Since pure Silver is too soft for standard jewelry work, Copper is added to the Silver alloy to generate the required mechanical strength. Sterling Silver alloy contains 92.5% Silver and 7.5% Copper.

999 Silver, or fine Silver, is pure Silver or more accurately 99.9% Silver. It is a very soft Silver metal used generally in wire jewelry and stone wrapping.
