Necklaces Platinum over Silver Simulated Diamond
Necklace & Bracelet Clasp Types
A clasp is more than a practical device used to fasten your jewelry. It is part of the overall design and can be a very important focal point. Be sure to consider if it will suit your needs of durability, fashion, comfort and peace of mind.
Lobster Claw Clasp: As a traditional clasp style found in bracelets and necklaces, the lobster claw is generally reserved for heavier styles that may need added strength. The closure's shape is more oblong, similar to a teardrop shape, and is controlled by a tip that opens and closes the spring in the clasp. This type is also considered a more expensive finding that can add to the overall value of the jewelry piece.
Magnetic Clasp: The popularity of the magnetic clasp has greatly increased in recent years. It is a quick and easy way to secure jewelry while not having to fuss with a tiny clasp, which can be difficult if you have long fingernails, arthritic hands or other mobility challenges. A magnetic clasp relies on a strong internal magnet that works to pull both ends of the clasp together. In most cases, a magnetic clasp is used for light to medium weight jewelry pieces that do not put excessive stress on the magnet.
Slide Insert Clasp: This type of clasp is exactly as it sounds. With a box-like shape that is hollow on the inside, the wearer will slide the nearly-flat tab into the box until it clicks, indicating a secure closure. On some jewelry, a slide insert clasp will be accompanied by a side safety catch, which adds strength and security to the clasp. Although this type of clasp is found on both bracelets and necklaces, it is particularly popular on bracelet styles. These types of clasps are often reserved for more expensive jewelry.
Spring Ring Clasp: One of the most common closure types, the spring ring clasp is typically used for light to medium weight bracelets or necklaces. It is round in its design and features a small tip which controls the opening and closing of the spring. The circle then closes around another smaller loop or link at the other end of the strand.
Toggle Clasp: A toggle clasp is a narrow piece of metal, usually designed in the shape of a bar, which is then pushed through a circular ring to act as a fastener. Unlike the lobster claw or spring ring clasps, a toggle clasp is not controlled by a spring. The pretty design is less secure than other closure types, but is usually meant to be a big part of the design and is meant to "show". The clasp is an attractive way to secure a chunkier link bracelet or necklace.
Platinum Plating
Platinum can be used as a finish coating over sterling silver or copper alloys. Its bright, pure luster enhances the brilliance of gemstones and does not discolor or oxidize. Platinum plating is also characterized by its good resistance to surface abrasion, making jewelry pieces more durable against everyday and long-term wear. Over time, platinum plating will wear off and therefore will require re-plating.
Platinum Embraced
Our Platinum Embraced collections feature layers of precious platinum over sterling silver or bronze for a rich, lustrous, radiant finish everywhere you look and touch.
To care for your plated jewelry items:
Remove jewelry before bathing, swimming, washing hands, putting on make-up, lotions, perfumes, and/or working with household chemicals, cleaners, or acidic liquids.
Do not clean plated jewelry in an ultrasonic cleaner or in silver cleaning solutions, as it could completely remove the plating finish from your item.
Ensure your jewelry item is thoroughly dry before storing. Moisture in an enclosed space can increase tarnishing.
Store your plated jewelry in a jewelry box lined with felt or anti-tarnish material. Items should not be stacked as this may cause damage to the plating surface.
Do not use excessive pressure when cleaning with a polishing cloth or soft brush, as this may cause damage to the plating.
Over time your plated items will need to be re-plated. Contact your local jeweler for information on plating services.
On the Mohs Scale, which measures the hardness of minerals, simulated diamonds are an 8.0 to 8.5. Ruby, sapphire and diamond are all harder substances, but simulated stones are still very durable. It is important to understand that hardness is not necessarily related to durability. Even though diamond is the hardest mineral (10.0 on the Mohs Scale), it can still be chipped or broken.
The only ways to tell the difference between simulated diamonds and diamonds are by use of a thermal probe, by weighing the loose stone or by microscopic examination of surface features and inclusions. Simulated diamonds weigh approximately 65% more than diamonds. Therefore, while a 6.25 mm round diamond weighs about 1.00 carat, the same size simulated diamond weighs about 1.65 carats. If you know the weight of a simulated diamond, you can figure out the diamond weight equivalent by multiplying its weight by 0.6, or 60%.

Dispersion: Flashes of rainbow colors. Also called “fire.”
Hardness: Resistance to scratching. The higher the number, the more resistant.
Luster: The shininess of a jewel.
Toughness: Resistance to breakage.
