Kim Zolciak showed off her engagement ring on Twitter. Is it bigger than that other Kim's engagement ring?

Zolciak got engaged to Atlanta Falcons player Kroy Biermann earlier this year after giving birth to the couple’s son, Kroy Jagger. She’s been pretty mum on a lot of the details, though a ring photo tweeted on Tuesday shows she’s got major bling status right now.

At 10-carats, it’s not bigger than Kardashian’s ring -- but we have to say it looks better than Kimmie’s ring. The cut gives off a larger-than-life vibe -- fitting for Zolciak’s personality.

Titanium is versatile, lightweight and strong, with a silvery-white metallic color. This metal is as strong as steel but is 45% lighter in weight, and is similar to platinum in it’s resistance to tarnishing. This metal has many uses ranging from armor plating, spacecraft and aircraft parts, to jewelry design. Titanium’s strength, durability, and lustrous beauty make it an ideal choice for jewelry, especially for rings and bracelets that are subject to daily wear.

The standard for sterling silver has remained unchanged since 1300 when Edward I of England established an early trade practice rule for silversmiths, decreeing that sterling must consist of 92.5 percent pure silver alloyed with 7.6 percent copper. The term "sterling" refers to the composition of the metal, never to the weight of a finished item.

Silver is much more plentiful than gold; however, silver tends to tarnish, making it less popular in some forms of jewelry. Like gold, silver is too soft for use in its pure state and must be combined with other metals for durability. Jewelry made of silver parts and gold parts must carry dual designations such as "Sterling and 10K."

The most precious metal commonly found in jewelry is the silvery-white metal platinum. It is a relative newcomer to jewelry, having become popular in the past 200 years or so. Like gold, it is rare and heavy, but it is more durable than gold and is sold in purer form. It is sometimes mixed with a little bit of iridium and ruthenium, which are similar to platinum but much rarer, for added strength. Platinum is not sold according to karat weights. It is stamped PT or plat in the United States to indicate that it is platinum.

Because of its purity, platinum is excellent for people who are allergic to other metals. Its light color also makes it popular. Like white gold, it makes very white diamonds appear bright.

Platinum has enjoyed an enormous resurgence in popularity in recent years. It has a very understated and old-fashioned look that has come back into style, leading more jewelry designers to work with this metal.

White gold has the same properties as yellow gold, but it has been mixed with different metals to give it a white color. Instead of the copper and silver used in yellow gold, white gold contains such metals as nickel, zinc, or even platinum. However, white gold should not be confused with platinum, which is much rarer than gold and hence more valuable.

The karat weight system used in white gold is the same as that used in yellow gold. 18K yellow gold and 18K white gold contain the same proportion of gold; only the remaining 25% of the alloy is different. Sometimes, white gold is plated with an even whiter metal, such as rhodium (a very rare member of the platinum family), to enhance its appearance.

White gold was developed to give a different look to jewelry. The white color is an excellent setting for very white diamonds, and when used side by side with yellow gold, it creates a striking effect. Jewelry using both white and yellow gold is called "two-tone."
