Birthstones

Ruby is the birthstone for July. This priceless diamond is distinguished by its deep hue, which stands for daring, passion, and love. The presence of chromium gives rubies, a kind of the mineral corundum, their distinctive colour. The world's best rubies are found in Myanmar, but they can also be found in Thailand, Sri Lanka. Due to their strength and rubies are one of the toughest gemstones, second only to diamonds, and are frequently used in engagement rings.

The March birthstone is aquamarine, which is typically a pale blue or greenish-blue color.

Garnet is January's birthstone because it is believed to symbolize friendship, trust, and loyalty. It is associated with qualities that are commonly valued in the month of January, such as starting the new year with strong relationships and a sense of stability. Additionally, garnet's deep red color aligns well with the themes of warmth and vitality often linked to the winter season.

It is difficult to provide an exact number of people born on June 4th, but statistically around 0.274% of the world's population is born on this date each year.

Sapphire itself is not waterproof as it is a type of gemstone. However, sapphire is often used as a watch crystal due to its hardness and scratch resistance, which can provide some level of water resistance for the watch it is used in. It is the construction and engineering of the watch case and seals that determine its waterproof qualities.

"835" stamped on a ring refers to the silver purity level, indicating that the ring is made of 83.5% pure silver. This is a common silver content used in jewelry making, especially in European countries such as Germany.

Kristen Stewart's birthstone is April's birthstone, which is diamond.

The birthstone for the month of February is Amethyst.

There is no birthstone for birthdays, only birthstones. But November's birthstone is Citrine.

Birthstones get their color from the presence of specific trace elements or impurities within the crystal structure of the gemstone. These elements interact with light in various ways, such as absorbing certain wavelengths and reflecting others, resulting in the unique color of the birthstone. The specific chemical composition and crystal lattice structure of the gemstone determine the color it exhibits.

Cancer - the Zodiac Sign - is from June 22 to July 22. However Birthstones are listed monthly. So the June birthstone is Pearl (white) and the July birthstone is Ruby (red). Hmmm...now you can also use Rhodalite or Alexandrite for June or Moonstone. Probably (in my very humble opinion)the best color for Cancer birthstone would be Red.

Opal & Pink Tourmaline are October birthstones. Opal is a traditional October birthstone and tourmaline is the modern birthstone for October.

The tourmaline is a semi-precious gemstone that is known for its vast variety of colors. As October is, however, the month of pink everything, the pink tourmaline is normally the preferred choice of Tourmalines. Pink tourmaline comes from a variety of crystalline boron silicate minerals, also known as rubellite. It has a sister stone that comes in the shade of blue, the Paraiba tourmaline. Comparatively, pink tourmaline has graced the market for a longer period of time than Paraiba.

Opals, known significantly for their dramatic play of color, or shifting hues depending on light, are as magical as everyone claims them to be. Opal too comes in a rainbow variety of shades, ranging from whites to blacks to greens, giving us a huge collection to choose from. Opal comes from a hydrated amorphous form of silica, and due to its amorphous form, it is known as a mineraloid.

The Density of an Amethyst Rock is 2.65 according to many sites.

In Spain, France, Scotland, Russia, and Brazil

Opal is known for its cleavage, which is the tendency of the stone to break along certain planes due to its crystal structure. This can give opal a characteristic pattern of fractures or cleavage surfaces when it is damaged or cut.

Aquamarine typically ranges in color from light blue to greenish-blue. While blue is the most common color, some can exhibit greenish tones due to trace amounts of iron.

To convert grams to carats for a ruby stone, you would multiply the weight in grams by 5. Carats = grams x 5. Thus, for an 8.5 gram ruby stone, the weight in carats would be 8.5 x 5 = 42.5 carats.

The Pearl River is named for the pearl-colored shells that were once found along its banks. The name comes from the Chinese word "zhujiang," which means "Pearl River."

The most common cuts for amethyst gemstones are oval, round, cushion, and emerald cuts. These cuts are popular for showcasing the deep purple color and natural brilliance of the stone.

There are several birthstones for each month. It just depends on which source you choose to use your birthstone from. The Traditional birthstones are the birthstones assigned by the Tiffany Co. in 1870. The Modern list was made by the Jewelers of America association in 1912 and last updated in 2002.
Here is a list of birthstones for October from different sources:

Traditional: Tourmaline, Aquamarine
Modern: Opal, Tourmaline
Mystical: Jasper
Ayurvedic: Opal

Amethyst is a variety of the colorless mineral quartz whose chemical formula is SiO2 (silicon dioxide). Its purple hue comes from minuscule amounts of impurities. It is a 7 on the hardness scale.

Alexandrite is a variety of the mineral chrysoberyl whose chemical formula is BeAl2O4 (an oxide of beryllium and aluminum). It is considered a green to yellowish green mineral in natural daylight, but its color appears dark pink to purple/cherry in artificial incandescent light. This property comes from minuscule impurities of Cr(III) (chromium in the +3 oxidation state) that reflect the excess green wavelengths found in the spectrum of natural sunlight and reflect the excess red found in the spectrum of incandescent light. Ordinary chrysoberyl does not demonstrate this so-called alexandrite effect. It is an 8.5 on the hardness scale.

The two mineral species also occupy different crystal systems, broadly defined by the symmetry of their atomic arrangements. Quartz, and thus amethyst, belongs to the trigonal system, and chrysoberyl, and thus alexandrite, belongs to the orthorhombic system.

Quartz is one of the most common minerals on earth (think of sand), though amethyst is far more rare, and chrysoberyl is also a relative rarity. Natural alexandrite on the other hand, comes from less than a couple of dozen localities in the world, and this scarcity drives its high price. Artificial or synthetic alexandrites are marketed commonly because of the high price of the natural ones. The only similarities shared by amethyst and alexandrite are that they are birthstones and that they are valuable because they are durable, scarce, and attractive.

Well, they are woth something, the specific answer being specific to the individual piece of jewelry. In general, larger diamonds are rarer and thus more valuable, so a cluster containing larger diamonds is generally worth more per carat than one with smaller diamonds, and not as much as one single diamond of that same weight. Diamonds really need to be over a carat in weight before they have a significant resale value. Most places that buy inexpensive clusters from the public will probably offer 100.00 a carat or less.

In Pokemon Sapphire, you can find a Corphish, the pre-evolved form of Crawdaunt which is the Hoenn region's equivalent of Crabby, in various locations such as the Petalburg city water routes, Lilycove city water routes, or Mossdeep city water routes by fishing with a Super Rod. Level it up to level 30 to evolve it into Crawdaunt, the Pokemon similar to Krabby.
