18kt gold


Today, there are many choices of metals for an engagement ring.  Over the years, engagement ring settings have become just as important as the diamond itself.  Gone are the days of the traditional yellow gold four prong solitaire style rings.  These days, settings are more elaborate and stylish.

Platinum is rare, pure and known for its durability.  Platinum is 95% pure and will not fade or tarnish keeping its rich white color for a lifetime.  With everyday wear platinum will develop a patina overtime.  Platinum is extremely strong and will hold precious stones firmly and securely in place.  Platinum will scratch, but unlike other metals no metal is lost it is just displaced.  Platinum is hypoallergenic and is a great choice for someone with sensitive skin.

Palladium is part of the platinum family and has a grayish white tone.  It is 10% stronger than platinum and consists of 95% palladium and 5% ruthenium which makes it more scratch resistant than platinum.   Palladium is also a hypoallergenic metal.

White Gold, available in 10kt, 14kt or 18kt, is pure gold alloyed with palladium, zinc or nickel.  The alloys in white gold make it stronger than yellow gold.  To mask the slightly yellowish tone in white gold it is rhodium plated giving it a bright white finish.

Yellow Gold, available in 10kt, 14kt or 18kt, is pure gold alloyed with copper and silver.  Its color looks great with all skin tones and gemstones.

Rose Gold, available in 10kt, 14kt or 18kt, is pure gold alloyed with copper.  Rose Gold has a soft tone that compliments the skin’s natural coloring.  Rose Gold comes in a variety of shades from reddish to a soft pink.  Rose Gold is not recommended for individuals with metal allergies because of its copper alloy.

Two-tone is a combination of two different color metals.  The most common two-tone rings are either platinum or white gold with either yellow gold or rose gold.

The purity of gold is described as karat (US) or fineness (Europe).  Pure gold is alloyed (combined) with other metals to make it more affordable, durable, and to change its color.   The minimum karat weight that can be sold differs from country to country.  In France and Italy gold must be at least 18kt to be called gold.  In the US and Japan gold must be over 10kt to be considered legal.  The two most common karat marks are 14kt and 18kt.  18kt is considered the international and US standard for high quality jewelry.  In India 22kt gold is popular because it is considered a monetary investment and the deep yellow color is more popular over the lighter alloyed shades of gold.
