Century Diamonds - Metal Type Guide

Gold

Gold is a jewelry staple for most fine jewelry pieces. In its purest form (24-karat), gold is too soft for use in wearable jewelry. When used to make rings, earrings, pendants and other jewelry gold is typically alloyed with other metals like silver, nickel, copper and zinc to add strength and durability. The ratio of alloy added to gold content is what determines the gold’s purity or carat weight. A gold purity of less than 14K or greater than 18K is not recommended for use in high-quality jewelry. At Century Diamonds, all of our jewelry pieces are offered in either 14K gold, 18K gold, or platinum.

18K Gold

18K gold consists of 75% gold and 25% alloy metals. Most jewelry experts consider this karat weight to possess the ideal balance of metal purity and strength. For those who prefer yellow gold, 18K exhibits a deeper, richer coloring than 14K yellow gold.

14K Gold

14K gold consists of 58.3% gold and 41.7% alloy metals. Priced moderately less than 18K gold, it’s a popular choice for those shopping on a budget. For those who prefer white gold, 14K offers a whiter coloring than 18K white gold.

 

White Gold vs. Yellow Gold

At Century Diamonds we do not charge extra for white and yellow gold and they possess the same levels of durability and gold content. If you’re pondering whether to choose white or yellow gold, here are a few suggestions to help with your decision:

Yellow Gold

If you (or the person you are buying the jewelry for)  typically wear mainly yellow gold jewelry, choosing that metal for will compliment her current style. Yellow gold is a classic choice for jewelry, complimenting those with warmer skin tones.

White Gold

If she currently wears white gold, platinum or sterling silver jewelry, a white gold engagement ring may be a wise choice. White gold offers a smooth, contemporary appeal and blends well with other jewelry pieces and clothing colors. 

 

Two-Tone Gold

Two-tone gold jewelry is the combination of both yellow and white gold in one ring. Century Diamonds offers 14k two-tone settings with the following guidelines (please contact us if you are interested in 18k two-tone): 

White Shank/Yellow Setting

This combines a white gold ring with a yellow gold setting. Ideal for diamonds with a bit more color to them.

Yellow Shank/White Setting

This combines a yellow gold ring with a white gold setting. Ideal for someone who wants a yellow gold ring, but doesn't want a colorless diamond to appear yellow due to the setting.

Platinum

Quickly growing in popularity, platinum is the most precious and rare of metals used in jewelry settings. Its highly durable and tarnish resistant. This makes for a worry-free choice for those who are very active or work often with their hands. Platinum is 95% pure, and its hypoallergenic qualities make it ideal for those with sensitive skin. The rarity of platinum enhances its appeal and its market value.


Platinum vs. White Gold

While white gold and platinum are both white metals that beautifully reflect light, there are some fundamental differences between the two. If you’re leaning toward a white precious metal and are undecided between platinum and white gold, here are a few points that may help with your decision. Platinum is 95% pure, while white gold is 58.3-75% pure. If allergies or skin sensitivities are a concern, platinum is more hypoallergenic. Platinum is harder and more durable than 18K white gold (although platinum can be scratched, so is not entirely damage-proof). While platinum retains its solid white coloring permanently, white gold can begin to exhibit a slight yellow hue over time as the outer layers of metal wear off. At Century Diamonds, we coat each of our white gold jewelry pieces with a protective layer of Rhodium, a metal that creates a white, gleaming look similar to platinum. White gold should be re-coated in Rhodium periodically to help maintain its original luster. For those who prefer the look of platinum but need an economical alternative, white gold offers much of the same visual appeal at a significantly lower price. Whatever metal you choose, most of the engagement rings offered at Century Diamonds are designed with a platinum head, ensuring a secure setting for your center certified diamond.
