White gold and rhodium

Rhodium, white gold

Did you know…Rhodium and white gold.

First and foremost, please understand that white gold does not exist in nature; white gold is a man-made product. Pure gold is 24kt and is a very bright yellow, not white. So what is white gold?
Imagine 24 identically sized bb’s of pure gold. If you melt all 24 of them together, you will have a blob of 24kt gold. If you remove one 24kt bb and replace it with another bb of any other metal (remember, there always has to be 24 bb’s when you melt them down) you will have 23kt gold.
Okay, follow the math here; if you take 10 of the 24kt bb’s away and replace them with 10 bb’s of nickel or zinc and melt all 24 of them together, you will have 14kt white gold. Therein lies the problem. You have 10 white bb’s and 14 bright yellow bb’s, thus, 14k white gold will always have that slight yellow sheen.
10kt white gold on the other hand contains 14 parts white to 10 parts yellow. 18kt white gold…well, it should be outlawed in my opinion because its 18 parts yellow and 6 parts white…aka…Slight Yellow Gold!
Rhodium on the other hand is a naturally occurring bright white member of the platinum family that lends itself very well as a plating material. Since its naturally bright white, when you use rhodium to plate a ‘whitish’ metal like 14kt white gold, it brightens it up and makes it appear whiter. Lotions, hand sanitizers and other materials cause the rhodium to dull over time, showing the slight yellow sheen. The process is not permanent and will need to be repeated sometime in the future.

November Birthstone, Part 1


Sunny and affordable, citrine blends especially well with the yellow gleam of polished gold. This yellow to gold quartz is readily available; in fact the largest faceted gemstone in the record book is a 19,548 carat citrine.

Named from the French term for lemon, citron, many citrines have a juicy “lemon” color.

In ancient times, citrine was carried as a protection against snake venom and evil thoughts.

Sometimes you will hear citrine incorrectly referred to as topaz quartz. Since topaz is different mineral, the industry has ruled to eliminate this name.

Along with topaz, citrine is one of the US birthstones for November.

Citrine includes transparent quart from yellow to “honey” to orangy brown.

Although the darker orangy brown to reddish orange color, called Madeira citrine, has traditionally been the most valued, recently the bright “lemon” color has been more popular.

Citrine is generally more affordable that amethyst, its quartz sibling. Like all quartz gems, citrine is relatively plentiful and is available in a wide range fo sizes and shapes, including very large sizes. Citrine is also popular for designer cuts and carvings.

Most citrine on the market began as amethyst that was heated to turn its color to “gold”

Citrine has a hardness of 7 on the Mohs scale, It’s durable and great for everyday wear.

Clean citrine with mild dish soap: use a soft toothbrush to gently scrub behind the stone where dust can collect.

Citrine jewelry should be kept away from prolonged exposure to strong light or heat.
