Elegance and Uniqueness comprise Tension Rings

It is their smooth, sleek lines and natural elegance that accentuates the beauty of tension rings. The tension settings have become the ultimate in contemporary engagement ring design. In a tension ring, the perfection and beauty of the diamond or any other gemstone would be highlighted rather than adding any distracting embellishments. Tension settings have become an instant classic in the contemporary ring designs owing to its minimal and elegant look.

In a tension ring setting, the diamond or other gemstone appears to be floating or suspended in the mid air within the band of the ring itself. This setting uses specially treated metals that have an inherent springiness nature to hold the ring in place. The entire band of the ring acts as two large prongs to hold the stone in place with small carved niches that fit around the stone’s girdle. The stone is help securely in place in a unique floating illusion with a great tensile strength.

Initially couples were having concern over the safety of the stone as it is held in place through two points of contact rather than the typical four or six prongs settings. This concern is however quite contrary. Tensions rings can be considered as one among the safest pieces of jewelry available. Since the band metal is stronger than that used for prongs and more of the metal is in contact with the stone than through narrow prongs, the stone in a tension setting is held more securely. Thus the stone achieves a stronger and tighter fit. The quality and craftsmanship of Novori engagement rings is backed up with the lifetime warranty.
Titanium is the most common metal used for tensions rings due to its natural strength and durability. At Novori jewelry there are designs in white gold, yellow gold and platinum. Couples even have the choice of selecting multi tone rings typically with an inset of a contrasting metal. We offer exquisite designs of tension rings in dual metal setting combining white and yellow gold.

The tension rings calls for talented workmanship and hence only a few exclusive jewelers would be able to create a quality tension ring setting. At Novori you can find customized one-of-a-kind rings that are examples of excellent craftsmanship. Customers would be overjoyed to find out that we also offer matching tension ring wedding bands at our jewelry store. Thus you can complete your engagement and wedding band set with style and elegance which is exclusive for tension rings.

Diamond Ring

In mineralogy, diamond  is an allotrope of carbon, where the carbon atoms are arranged in a variation of the face-centered cubic crystal structure called a diamond lattice. Diamond is less stable than graphite, but the conversion rate from diamond to graphite is negligible at ambient conditions. Diamond is renowned as a material with superlative physical qualities, most of which originate from the strong covalent bonding between its atoms. In particular, diamond has the highest hardness and thermal conductivity of any bulk material. Those properties determine the major industrial application of diamond in cutting and polishing tools.
Diamond has remarkable optical characteristics. Because of its extremely rigid lattice, it can be contaminated by very few types of impurities, such as boron and nitrogen. Combined with wide transparency, this results in the clear, colorless appearance of most natural diamonds. Small amounts of defects or impurities color diamond blue (boron), yellow (nitrogen), brown (lattice defects), green, purple, pink, orange or red. Diamond also has relatively high optical dispersion (ability to disperse light of different colors), which results in its characteristic luster. Excellent optical and mechanical properties, combined with efficient marketing, make diamond the most popular gemstone.

Most natural diamonds are formed at high-pressure high-temperature conditions existing at depths of 140 to 190 kilometers (87 to 120 mi) in the Earth mantle. Carbon-containing minerals provide the carbon source, and the growth occurs over periods from 1 billion to 3.3 billion years (25% to 75% of the age of the Earth). Diamonds are brought close to the Earth surface through deep volcanic eruptions by a magma, which cools into igneous rocks known as kimberlites and lamproites. Diamonds can also be produced synthetically in a high-pressure high-temperature process which approximately simulates the conditions in the Earth mantle.

An alternative, and completely different growth technique is chemical vapor deposition (CVD). Several non-diamond materials, which include cubic zirconia and silicon carbide and are often called diamond simulants, resemble diamond in appearance and many properties. Special gemological techniques have been specially developed to distinguish natural and synthetic diamonds and diamond simulants.
