Gems and Precious Stones

Diamonds are mined, not quarried. Diamond mining involves extracting diamonds from the earth's crust, typically through open-pit or underground mining operations. Quarries, on the other hand, are used to extract building materials like stone, sand, and gravel.

Gemologists, geologists, miners, and collectors typically seek out precious stones in various locations such as mines, rivers, and gemstone markets. These individuals often have specialized knowledge and tools to identify, extract, and evaluate precious stones.

Opal is a gemstone because of its distinctive play-of-color, which is a unique iridescence that reflects a rainbow of colors. It is formed from silica-rich solutions that fill cavities in rock formations, resulting in its characteristic color display. Opal is valued for its beauty and rarity, making it a sought-after gemstone in jewelry.

It is, so diamond will become graphite over time. The structure of diamond hinders the necessary kinetics, so the process is very slow, unnoticeable most of the time.

It's because the standard enthalpy of formation of graphite is 0; but diamonds is not equal to 0.

According to Wikipedia:

Black opal can be very expensive, only low grade black opal is sold by kilo weight. This low grade is called potch and colour which means that maybe bit of colour might be in this rough black opal I have seen parcels sold for $200 per kilo but it has no colour. Good kilo bucket of rough black opal would cost around $5,000 .00 Black opal is rated by body tone N1 for deep black colour, and N4 for light black colour. So for $5000 per kilo, dont expect N1 body tone. Black opal is sold by carat, and rare patterns are worth $5,000 to $20,000 per carat; especially red fire harlequin pattern n1 body tone, and over brighness rating of 4.

Yes, a laser cutter can cut diamond because diamond is a carbon-based material, and carbon can be vaporized by a high-powered laser. However, the process can be challenging due to diamond's exceptional hardness, which can damage the laser cutter's lenses and mirrors. Specialized techniques and equipment are required for cutting diamonds with a laser cutter.

Diamonds are measured in carats, which is a unit of weight equal to 200 milligrams. This weight measurement is used to determine the size and value of a diamond.

It depends on the cut, clarity, color, size, and other factors. A large, single emerald is worth more than a collection of stones that total six carats. Emeralds are worth less if they are heavily flawed or treated to hide flaws. A single stone of this size may be worth very little compared to a perfect emerald one-tenth the size.

The price of turquoise can vary depending on the quality, size, and origin of the stone. On average, turquoise can range from $1 to $10 per carat for lower-grade stones, and up to several hundred dollars per carat for high-quality, rare turquoise. Specialty or artisan pieces can command even higher prices.

The value of a 40 carat uncut aquamarine can vary greatly depending on its clarity, color, and overall quality. Generally, uncut gemstones are valued lower than cut and polished stones. On average, a 40 carat uncut aquamarine may be valued between $500 to $1500 per carat, but prices can fluctuate significantly.

For diamonds, carat is the weight. I suspect that your 1.0 stone is a 1 carat stone.

Milliliters (ml) is a measure of liquid volume, which doesn't apply to diamonds, since they are not liquid.

To determine the estimated value of an opal necklace and earrings surrounded by small diamonds, you can take them to a trusted jeweler for appraisal. They will assess the quality and characteristics of the opals, diamonds, and settings to provide an estimated value based on current market trends. Make sure to get a written appraisal for insurance purposes.

One way to differentiate between a diamond and glass is through their hardness level. Diamonds are one of the hardest natural substances, so they can scratch glass, while glass cannot scratch a diamond. Another method is through their refractive index; diamonds have a higher refractive index than glass, leading to more sparkle and brilliance in a diamond compared to glass. Consulting a professional jeweler or gemologist is the most accurate way to determine if a stone is a diamond or glass.

No, emeralds are not hard enough to cut glass.

Diamonds cut glass and they are the only gemstone with this capability.

Yes, blue sapphire and pearl can be worn together as they complement each other well. Blue sapphire is associated with wisdom and protection, while pearl symbolizes purity and emotional balance. When worn together, they can create a harmonious and balanced energy.

An authentication process for a diamond is usually formalized on paper. You can find an example, below.

Any mark stamped into the jewelry metal cannot authentically reflect the stones set into the metal, since the metal and the stones can easily become separated.

Any laser mark on a diamond will be an identification mark for the stone. The stone's authenticity, then, must be pursued through the holder of the mark and paper authentication obtained through them.

Since not all of the diamonds in the earth have been unearthed, it is not possible to post a number that has any validity.

Natural red diamonds, however, are the most rare of naturally coloured diamonds.

It could be worth nothing or a great deal - depending on the form it takes. Compare a perfect 8 oz. Herkimer quartz crystal versus 8 oz. of silica sand. Great difference in worth. Quartz is the most common mineral on Earth, so when dealing in ounces only a good specimen will have value for the most part.

Diamonds and gemstones are not renewable resources, so there is a finite supply in the earth. However, the rate at which they are mined and used is carefully managed by the industry to ensure sustainable sourcing practices. While they won't "run out" per se, there may come a time when certain types of gems are harder to find and become more expensive.

Stone is typically obtained from quarries where rocks are extracted and then cut into desired shapes and sizes for various uses in construction or landscaping. Slate is a type of stone that is formed from compressed layers of sedimentary rock and is usually mined from quarries in large blocks that are then split into thinner sheets for use in roofing, flooring, and other applications.

A person who makes and sells articles of gold is known as a goldsmith or jeweler. They typically work with gold to create jewelry, such as rings, necklaces, bracelets, and other accessories. Goldsmiths may also offer customization services for clients looking to create unique pieces.
