FREQUENTLY ASKED
When choosing the right metal for a luxury diamond ring, we suggest prioritizing precious metals like 18K gold or platinum. Cheaper metals like bronze, zinc, copper, or nickel can be irritating for sensitive skin. Silver and gold-plated rings are known to tarnish or fade over time, reducing the aesthetic appeal and longevity of the piece. At Diamonds by Avi & Co., we craft our elegant diamond rings from only the finest metals. Our selection of 18K white gold, 18K yellow gold, and platinum rings are hypoallergenic and pure, making them safe to wear and ideal for lifelong heirlooms that you hope to pass down for generations to come.
Eternity bands and engagement rings showcase two popular luxury diamond ring styles. An engagement ring is typically designed around a prominent center stone. While there may be other stones on the ring, the center stone is usually the largest and stands out from the rest. An eternity band, on the other hand, features an unbroken line of diamonds that continue around the entire circumference of the band. These stones are typically equal in size, leading to an appearance of infinite diamonds encircling the finger. While an engagement ring is usually given to mark a proposal, an eternity band may be given to celebrate a number of different milestones, including marriage, the birth of a child, or even a major anniversary or birthday.
Every diamond cut has advantages and drawbacks, and finding the best diamond for your ring is a matter of personal preference and taste. That said, there are some diamond cuts that tend to appear larger even at the same carat weight as another cut. Elongated shapes like a marquise cut, oval cut, pear cut, or elongated emerald cut take up more real estate on the finger, making the stone appear larger. On the other hand, round, Asscher, and cushion-cut diamonds may have more of the diamond’s weight on the lower half, making them deeper yet less wide or long. These differences create an optical illusion that makes certain diamond cuts appear larger, even when they weigh in at the same carat weight.
The round brilliant cut diamond has long been the most popular, timeless cut for engagement rings and continues to account for about 70% of all engagement rings sold. However, other diamond cuts are climbing up the rankings as modern brides look for unconventional appeal and unique rings that are full of personality. Other popular diamond shapes for engagement rings include oval cut, cushion cut, emerald cut, and princess cut. In recent years, the marquise cut diamond has also gained attention and has been a favorite of some prominent celebrities.
A solitaire ring setting features one central diamond. It might sit on a pavé diamond band or an unadorned precious metal band. The solitaire ring setting allows large diamonds to shine and show off their prowess and impact. With a halo ring setting, the central diamond is surrounded by a “halo” of smaller diamonds. This creates an optical illusion that can make the central stone appear significantly larger. The halo setting is also common for colored “fancy” diamonds, offering aesthetic contrast that makes the brightly colored stone pop even more. Both of these settings are common in luxury diamond jewelry and make for excellent options for the sophisticated modern woman.
