Metal Options

We are dedicated to creating high quality custom jewelry pieces with the potential to become family heirlooms that are passed down for generations. Because of this commitment, we work only with precious metals which, due to their higher luster and ductility, are the preferred metals for use in art and jewelry.

Silver, gold, platinum, and palladium are the most well-known precious metals and also the best of the group to use for making jewelry. These precious metals are also considered to be "noble" metals, meaning they are resistant to corrosion and oxidation in moist air, unlike most base metals. We offer all of these precious metal options to our clients but, we do usually recommend the more durable gold or platinum options instead of sterling silver for your wedding jewelry, since wedding bands and engagement rings tend to be worn every day over a lifetime. Of course, we are happy to work with whichever precious metal you prefer.


Takayas & Co. offers 14K and 18K gold in 4 different color varieties: yellow gold, rose gold, white gold, and gold plated with black rhodium.

White gold's bright, silvery color is improved with various alloys like nickel that are mixed in to help give it a more intense white sheen. As a final step, it is also plated with rhodium, an extremely hard and rare metal, which serves to improve white gold's durability and color. From time to time, you will have to re-plate the rhodium to restore your white gold's previous silver-white luster.

For customers who are interested in a black metal look for their jewelry piece, we can use black rhodium (plated over white gold) to give their jewelry a dark, rich color. Like regular rhodium, this black rhodium will need to be re-plated periodically over time.

Gold purity is measured in karats (which are different from carats, the standard gem weight measurement). 24K (twenty-four karat) gold is pure gold, however, because it is so soft and easily damaged, we do not recommend it for jewelry. 22K gold is also rarely used because its purity makes it too malleable and prone to scratching or bending. However, we are happy to offer 14K and 18K gold in our designs as they are the best balance between budget, strength, and gold content.



Platinum's rareness and durability makes it one of the most popular metals for jewelry like engagement rings and wedding bands that are designed to be worn everyday for a lifetime. Unlike sterling silver, platinum's naturally white sheen will never fade as it does not tarnish or oxidize and, unlike white gold, it will not require re-plating over the years.

Platinum is also 90%–95% pure and naturally hypoallergenic which makes it a great choice for anyone with metal sensitivities. While we recommend periodically bringing in all jewelry for cleaning and upkeep due to normal, everyday wear and tear, platinum requires the least amount of maintenance of all the precious metals.



Palladium is a rare silver-white metal that belongs to the platinum family. Like platinum, it also possesses a superior ability to withstand corrosion and oxidation and, as a result, palladium will retain its naturally white color without requiring re-plating.

Similar to platinum, one of the benefits of this 95% pure precious metal is that people with metal allergies find that their skin doesn't react negatively to it. Palladium also has a lower metal density which makes it a great choice to lighten up heavier jewelry pieces.

Sterling Silver


Sterling silver is the most affordable of the precious metals, and it is a beautiful, popular choice for those who love the white metal look but may be interested in something a little more modestly priced than platinum.

Of all the metals, silver is intrinsically more prone to tarnish, however, its brilliance is easily restored. If your silver jewelry piece begins to show signs of tarnish, this tarnish can be easily removed with silver polish and a polishing cloth available at any jewelry store.

Because pure silver is relatively soft and easily damaged, it is typically mixed with other metal alloys like copper and nickel to improve its hardness and durability. For some people with metal allergies, these alloys can irritate the wearer's skin. If you have any metal sensitivities, we usually recommend a purer metal like platinum or palladium for your jewelry.

Industrial Metals

Due to the intricate, three-dimensional nature of the designs Takayas creates, industrial metals such as stainless steel, titanium, or tungsten are typically not an option because his designs require precious metals which can be shaped by hand. Unfortunately, industrial strength metals can only be made into simple flat bands because they have to be cut in a factory with specialized machinery. This is also why rings made out of stainless steel, titanium, or tungsten are not resizable.
