Gems and Precious Stones

JWBR is likely a jewelry manufacturer's stamp or brand. It does not indicate metal purity like traditional hallmarks. It could be the maker's mark that represents the company or designer who crafted the ring.

A created opal is a type of synthetic opal that is made in a laboratory. It is created using a combination of silica spheres and a polymer resin material to mimic the appearance of natural opal. Created opals can display similar color play and patterns to genuine opals.

The breastplate worn by priests in ancient times, as described in the Bible, consisted of 12 stones representing the 12 tribes of Israel. Each stone was associated with a different tribe and symbolized various attributes or characteristics. The stones were considered to bring divine protection and guidance to the wearer during religious ceremonies.

I know that it was ages ago that you asked your question, but I just stumbled across Pink Fiord on eBay and wondered the same thing. I found this on a website:

Those of us who love Scottish jewelry are particularly fond of the quartz gemstones, for so many examples are set with the best-known of the quartzes, amethyst and citrine, both native to Scotland. In the past, when we thought of pink quartz, we thought of the opaque rose quartz. Now from Norway comes this beautiful transparent light pink quartz, known as Pink Fjord.

Hope that helps--yet another beautiful quartz!

Brilliant Cut, or Round Brilliant cut as it can also be called, is a round diamond ;its the generic and most common shape you will see for a diamond in jewellery, especially engagement solitaire rings.

Opal has a unique luster known as opalescence, which is a play of colors that appears to change and move as the gemstone is viewed from different angles. This luster is caused by the diffraction of light through the tiny spherical silica structures within the opal.

A mineral that is rare and can be cut and polished is called a gemstone. Gemstones are typically prized for their beauty, rarity, and durability, making them valuable for use in jewelry and other decorative items. Examples of gemstones include diamonds, rubies, emeralds, and sapphires.

The specific gravity of turquoise typically ranges from 2.60 to 2.85. This can vary depending on the specific composition and origin of the turquoise. Specific gravity is a measure of the density of a material compared to the density of water.

The stamp "18k HGE" usually indicates that the ring is gold plated with a heavy layer of 18 karat gold. The stones could be real or synthetic, but the stamp primarily refers to the gold content of the ring. It's best to consult a jeweler for a professional assessment of the stones.

The plural of topaz is topazes.

Pink tourmaline has a glass-like, "vitreous" luster.

An opal is considered to be a mineraloid, meaning that it has all of the properties of a mineral-- solid, inorganic, naturally forming, has a chemical composition-- but does not demonstrate crystallinity. Other examples of mineraloids include obsidian, an amorphous glass (that is not a crystal).

Most substances will react with some acid or another. Even glass will be dissolved by hydroflouric acid and even gold will dissolve in aqua regia. As for regular acids, I have put a sample of topaz in a hydrochloric acid solution and after three weeks, it was unchanged.

The density of topaz varies depending on its color and composition, but typically falls between 3.4 to 3.6 grams per cubic centimeter. This places it in a similar density range as minerals like quartz and feldspar.

Rhodolite garnet typically exhibits a pinkish-red to purplish-red color. It is known for its vibrant and rich hue, which can vary from a deep red to a lighter pink depending on the lighting conditions. Overall, rhodolite garnet is valued for its striking and intense coloration.

The Gachala Emerald is estimated to be worth around $1.15 million per carat due to its exceptional color and clarity. The exact value can vary depending on market demand and the specific characteristics of the individual stone.

A ruby has a lot of variables , that can determine the price. Clarity is a big factor. If it's really clear then you can get a lot of money for it. If it's blurry, then you could probably get $50 USD for it.

The other birthstone for October is the tourmaline, which comes in a variety of colors such as pink, green, and watermelon. It is believed to have calming and balancing properties, bringing a sense of harmony to the wearer.

Turquoise is neither precious or semi precious. It is not a gem, but rather a Phosphate mineral. It is included in birthstones and jewelry making as a stone, but is not.
It's a semi precious gemstone. cuz it's hardness is soft then precious.

A low quality diamond is often referred to as an industrial-grade diamond or a diamond with industrial use, sometimes known as bort. These diamonds are not used for jewelry due to their lower clarity and color grades.

The diamond-like gemstone found in some meteorites is called moissanite. It is composed of silicon carbide and is formed under high pressure and temperature conditions in outer space. Moissanite is known for its brilliance and durability, making it a popular choice for jewelry.
