old-mine-cut diamond
The old mine cut is a type of diamond cut that was popular in the 1700s and was most prevalent during the Georgian and Victorian eras. It is similar to today's cushion cut and is characterized by a squarish girdle with gently rounded corners, a high crown, a small table, and a large, flat culet.
Old mine cut diamonds are known for their antique charm and character, and they are often used in vintage-style jewelry. They have a softer, more romantic look than modern diamond cuts, which tend to have more precise geometry and a higher level of brilliance.
Old mine cut diamonds are typically less expensive than diamonds with more modern cuts because they require less labor and material to produce. They are often used as accent stones in jewelry designs or as the main gemstone in vintage-style pieces. Despite their lower price, old mine cut diamonds can still be beautiful and valuable, and they are a popular choice for those who appreciate the unique charm and character of antique jewelry.
onyx
Onyx is a type of chalcedony, which is a variety of quartz that is characterized by its fine grain and layered structure. Onyx is most commonly found in black and white bands, and it is known for its unique color pattern and ability to be carved into intricate designs.
Onyx has been used for centuries as a gemstone and has been prized for its beauty and versatility. It was especially popular in ancient times, when it was used to create cameos, which are small, carved gemstones that feature a raised design on a background of a different color. The layered structure of onyx made it especially well-suited for this purpose, as it allowed the engraver to cut the design in one color while creating a background of another color.
The term "onyx" is sometimes used to describe pure black gemstones, but this is technically incorrect. True onyx is always banded, with alternating layers of black and white (or sometimes other colors). Gemstones that are solid black are usually made of other materials, such as obsidian or black jade.
In addition to its use in jewelry, onyx is also used in various decorative objects and as a material for carving and engraving. It is a relatively hard and durable stone, and it is often used in jewelry and other decorative items that are subjected to wear and tear.
rose-cut diamond
The rose cut is a type of diamond cut that was popular in the 1500s and remained common during the Georgian and Victorian eras. It is characterized by a flat bottom with a dome-shaped crown that rises to a single apex, giving the diamond a shape that resembles a rose bud. Rose cut diamonds can have anywhere from 3 to 24 facets, which are small, flat surfaces that are cut into the diamond to create a specific shape and enhance its sparkle and brilliance.
Unlike modern diamond cuts, such as the round brilliant or princess cut, the rose cut has a lower crown and a less brilliant appearance. It is a more primitive diamond cut that was used before the development of more advanced cutting techniques. However, it is still a popular choice for collectors of antique jewelry and for those who appreciate the timeless beauty of vintage cuts.
Rose cut diamonds are typically less expensive than diamonds with more modern cuts because they require less labor and material to produce. They are often used as accent stones in jewelry designs or as the main gemstone in vintage-style pieces. Despite their lower price, rose cut diamonds can still be beautiful and valuable, and they are a popular choice for those who appreciate the unique charm and character of antique jewelry.
18k
18k gold is a type of gold alloy that is commonly used in jewelry making. It is made up of 75% gold and 25% other metals, such as copper, silver, or palladium. The addition of other metals helps to increase the durability and strength of the gold, making it more suitable for use in jewelry. 18k gold is softer and more prone to scratching than higher karat golds, such as 22k or 24k, but it is still a popular choice for jewelry because of its warm, yellow color and good resistance to tarnishing. It is also less expensive than higher karat golds due to the smaller amount of gold used in the alloy. 18k gold is a popular choice for engagement rings, wedding bands, and other fine jewelry items.
