Diamonds

The color of the streak on a diamond is usually white. When a diamond is scratched against a hard surface, it leaves a white streak due to the light reflecting off its facets.

Diamonds formed underground have more time to grow and develop under high pressure and temperature, leading to larger crystals. In a laboratory, diamonds are typically created using a faster process that may not allow for the same level of crystal growth, resulting in smaller sizes.

Generally yes.

If two diamonds, with similar carat weight, similar clarity and similar quality of cut are compared, the brown diamond will generally be less expensive than a white diamond.

Yellow diamonds, like all colored diamonds, get their color due to impurities or structural defects in the diamond crystal lattice during formation. In the case of yellow diamonds, nitrogen atoms are present in the crystal lattice, absorbing blue light and resulting in a yellow hue. The intensity of the yellow color can vary depending on the amount and distribution of nitrogen in the diamond.

Diamonds are adamantine to waxy in luster. Diamonds come in all colours, and varying shades of colours, including yellows, browns, grays, and also white, blue, black, reddish, greenish and colorless.

Industrial diamonds have been manufactured since the mid-1950s. These resources are produced from carbon under ultra high pressure and extreme temperatures in technical laboratories.

Every individual diamond may or may not have a natural fluorescence.

This characteristic is both a scientific factor and an emotional -- eye candy -- factor in a diamond.

Diamond is valued for its hardness, making it ideal for cutting, grinding, and polishing other materials. It is also used in jewelry as a precious gemstone due to its clarity, brilliance, and rarity. In industrial applications, diamond is used in drills, saw blades, and other tools for their high durability and strength.

A diamond with a color grade of I-J falls within the near-colorless range. This means the diamond will have a slight hint of yellow or brown tint, which may be noticeable to the naked eye. The overall quality and beauty of a diamond depend on factors such as cut, clarity, and carat weight, in addition to color.

If a ring is marked with 925, it typically means that the metal is sterling silver, not that the diamond is real. To determine if the diamond is real, consider factors like clarity, color, cut, and carat weight. It's best to seek a professional appraisal or diamond testing from a jeweler.

A real diamond is primarily composed of carbon arranged in a crystal lattice structure. To create a synthetic diamond, various methods can be used such as high pressure-high temperature (HPHT) or chemical vapor deposition (CVD) to replicate the conditions in which natural diamonds form. These methods require a carbon source, a catalyst, and high pressure or high temperature conditions.

You can purchase a diamond today from Blue Nile, of about this carat weight, with SI2 flaws and spend between US$4,178 and US$8,576, depending on the cut and clarity that you want.

Please note that an SI3 diamond borders on being less than gem-stone quality, since this elevated number of Inclusions may cause the stone to split or otherwise suffer a non-recoverable fatality with ordinary wear.

Best practices dictate that you work with a certified gemologist to evaluate any diamond purchase, especially an anticipated purchase of an SI3 diamond.

It's rather opposite. Although, moissanite is much rarer than diamond, but in real scenario most of the moissanites that you find in jewelry market are synthetic. These synthetic moissanites can be easily processed in lab and are also cheap.

So, it can be said that moissanite jewelry is actually cheaper than real diamond jewelry.

Diamond is the hardest naturally occurring material known, ranking as a 10 on the Mohs scale of mineral hardness. This means it is extremely durable and resistant to scratching or abrasion.

Diamonds are prized for their rarity, durability, and brilliance, making them highly valuable in jewelry and industrial applications. They are also symbolic of lasting love and commitment, often used in engagement rings. Additionally, diamonds have cultural significance in many societies and are seen as a status symbol.

To verify if a diamond ring contains real diamonds, you can have it examined by a professional jeweler who can assess the authenticity of the stones using specialized tools. A jeweler can perform various tests, like checking for diamond clarity and hardness, to confirm if the stones are genuine diamonds.

Since diamonds hold enormous value for their size, any metal used to set a diamond should be able to resist casual bumps and bangs, sufficient to protect the diamond.

Usually, diamonds are set in high-carat gold, 14 karat or 18 karat (higher karat gold is too soft), or platinum. Diamonds are also set in palladium, steel and other metals, but not typically in jewelery that will be bumped or banged.

No, diamonds cannot be made directly from human ashes. While it is possible to create memorial diamonds using carbon extracted from cremated remains, the process involves high pressure and high temperature treatments in a lab setting, rather than simply transforming ashes into diamonds.

Diamonds are formed deep within the Earth's mantle layer, around 150 to 200 kilometers below the surface. They are brought closer to the surface through volcanic activity and then mined for various industrial and jewelry purposes.

It is not typically possible to find diamonds in a coal mine. Diamonds are typically formed in the Earth's mantle, while coal is formed from plant material that has been subjected to high pressure and heat over time. The two processes occur in different geological settings.

Yes, diamonds are the hardest known natural material on Earth with a Mohs hardness scale of 10. However, it is important to note that hardness and toughness are two different properties. Toughness refers to a material's ability to resist breaking or shattering under force, and in this regard, some materials like metals may exhibit better toughness than diamonds.

When a diamond is cut or set, it is possible to do so with its flaws presented in a way that makes the diamond vulnerable to chipping. Either of these situations is rare if the diamond is cut or set by knowledgeable workers.

A less flawed diamond is less susceptible to chipping.

No, crushed calcite is not hard enough to grind or form facets on a diamond. Diamonds are the hardest natural material on the Mohs scale, while calcite has a much lower hardness rating. Specialized tools with materials of equal or greater hardness, such as diamond powder or industrial diamond grit, are typically used to cut and shape diamonds.
