Buyer’s Guide: Features to Look Out for Before Buying the Best Diamond Pendant

Verified Authenticity

It would be best to get diamonds from verified vendors or sellers specializing in jewelry for those who plan to buy natural, authentic diamond pendants. Reputable brands and sellers would even include a Certificate of Authenticity with your pendant item of purchase to guarantee your diamond’s legitimacy.

Grade and Quality

Diamonds are usually valued and priced based on how little imperfections dominate their surface or how clear and colorless they are. VS1-VS2 diamonds are flawless to the naked eye and are just a fraction less valuable than a truly flawless diamond. SI1-SI2s are diamonds with little inclusions that won’t be noticeable for a casual observer. However, for larger diamonds with more evident inclusions, VS2s at least would be the safest choice.

Colorless diamonds are considered the purest, making them more valuable. A diamond’s clarity is rated from D-Z, with D being the clearest, with it gradually being colored to yellow or light brown. They are color-graded by comparing them to stones with known colors under controlled lighting and precise viewing settings.

Suitable Diamond Size

Diamonds are usually measured in inches or millimeters through their diameter. They range from 3-11mm cuts to be conveniently strung into pendants or necklaces. The larger its size is, the more costly it would be, but it will also be more eye-catching, best used for formal events.

Preferred Shape or Design

Various diamond pendants are now being made with creative designs to match their elegance, such as halo, bar-lined, or heart-shaped diamond designs are emerging. However, some may still prefer the simplicity of a center strung diamond pendant that makes their brilliance enough for an eye-catching moment. A rounded-cut diamond is the most popular for its cut due to its maximized facets that make them shine the most. 

However, the classic solitaires are mostly preferred for their simplicity yet elegance they bring. They also maximize a diamond’s worth by buying it in one piece and simply picking a great shape, cut, and setting. The most popular cut is the four-prong solitaire diamond pendant that is timeless and classic. Other popular cuts are the marquise, princess, cushion, pear, Asscher, oval, emerald, etc. Other popular settings include bezel, scallop, kite, Milgrain, etc. 

Pendant Necklace Length

You need to match the pendant’s metal chain length with the width of your neck and how you’d like your pendant necklace to appear, hanging from your neck. Usually, diamond pendants that measure 16in around at most would most likely appear as chokers or leave minimal space, while 18in pendant chain lengths or more would drape down with enough space for your neck.

Durable Material

Ensure that your diamonds are protected with rims or plating, especially if they are situated near other gemstones, as they can scratch your other pieces of jewelry due to their superior hardness. They should be placed in a secure setting such as four or six prong metal or a jump ring to secure them on your pendant. The most secure setting for a well-protected diamond crystal would be the bezel type.

For the metal clasps or other metal strings or chains attached to your diamond pendant, ensure that they have a high-quality metal material to match the elegance of your diamonds. Most reputable diamond pendants would use white, rose, or yellow gold metal clasps or chains with some protective plating to make them resistant to tarnishing. 

A pendant would be more flexible to its metal chain material as it can easily switch with another without the hassle of removing your diamond crystal from its setting. In this case, you have a more flexible choice and freedom in choosing or replacing your metal chains from time to time.

Secure Metal Clasp

Most pendants can have flimsy clasps that can be severed easily, or some even complain of very complicated or hard to open clasps that would be an inconvenience if you were to remove them alone. You can discover other diamond pendants that provide a secure clasp that would have an uncomplicated opening and locking mechanism that wouldn’t compromise the security of your diamonds hanging on your neck. 

Though a pendant’s metal chain would be flexible as it is attached to a metal chain that can be easily replaced, it is still best to consider buying a high-quality metal clasp and chain as well to get the most out of your purchase.

FAQs – Frequently Asked Questions

How can you effectively test synthetic diamonds from genuine ones?

You must remember that lab-created or synthetic diamonds can also be classified as genuine diamonds and are valuable as well as they are made with the same structure as natural diamonds. However, naturally occurring diamonds can be distinguished from synthetic ones through a couple of tests that makes them extremely valuable. 

Thermal conductivity tests work for differentiating diamond simulants such as cubic zirconia from the naturally occurring diamond. However, a new diamond simulant called moissanite can only be differentiated using electrical conductivity tests. A naturally occurring diamond also has the hardest bonding pattern making it the hardest mineral in the Mohs Scale of hardness. Only a natural diamond can scratch another natural diamond.

How are naturally occurring diamonds formed, and where do they come from?

Diamonds are formed from the element carbon upon millions of years of exposure to extreme pressure and temperature, making them the strongest mineral or gemstone in the industry. This process means that they are found deep within the Earth’s subsurface and can be mined out through pipes that extend deep under the ground, such as kimberlites. 

The incredibly long and hard process for their formation and the complicated way of mining them out from the Earth’s surface makes them extremely rare, making them one of the most valuable and beautiful gemstones in the market.

Are diamonds a good investment?

Yes. Precious metals and stones increase in value as time progress. With the depletion of their raw materials on the Earth, they become rarer and harder to find and obtain. With the increasing demands of modern society, it wouldn’t be a surprise if a couple of years from now, your diamond has multiplied in value. 

As a gift, it would also be a good investment given to your loved ones. You would want to build a good relationship with them and appreciate how you send them a message that they are valuable to you.
