Buyer’s Guide: Notable Features to Look for Before Buying the Best Diamond Studs

Verified Authenticity

It would be smart to purchase diamonds from verified sellers specializing in jewelry, especially for those who plan to buy natural, authentic diamond studs. Most reputable brands and sellers would even include a Certificate of Authenticity along with your purchased item to guarantee your diamond’s genuineness. 

Grade and Quality

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

Colorless diamonds are considered pure, making them valuable. A diamond’s clarity or colorless property is rated from D-Z, with D as the highest grade, with it gradually colored to yellow or light brown. They are examined by comparing them to stones with known colors under precise viewing settings and controlled lighting. 

Suitable Diamond Size

Diamonds are measured in inches or millimeters through their diameter or their length and width dimensions. They usually range from 3-11mm cuts to be conveniently set on studs and earrings. The larger the crystal diamonds are, the more costly they would be, but they will also be more eye-catching, best used for formal events. 

Preferred Shape or Design

Various diamond studs are now being made with creative designs to match their elegance, such as halo, bar-lined, or various shaped diamond designs are emerging. However, some may still prefer a solitaire diamond stud’s simplicity, making their brilliance enough to be eye-catching. A rounded diamond is the most popular cut due to its maximized facets that make them shine the most. 

Classic solitaire studs are preferred for their simplicity and elegance. You can maximize a diamond’s worth by buying it in one piece and picking a great shape, cut, and setting that would match your style. The most popular setting is the four-prong solitaire diamond stud that is timeless and classic. Other popular cuts include the marquise, princess, cushion, pear, Asscher, oval, emerald, etc., while popular settings include bezel, scallop, kite, Milgrain, etc. 

Secure Locking Mechanism

Most earrings can have flimsy back locks that can be pushed back easily, or some even complain of very complicated or hard to open locks that would be an inconvenience if you were to remove them alone. Classic stud earrings would mostly feature the push-back lock due to their small body and relatively simple designs.

However, you may discover diamond earring backing locks that provide a secure hold or support for the back lock or a conveniently attached lever that would have an uncomplicated opening and locking mechanism that wouldn’t compromise the security of your diamonds hanging on your ears. These types of locking mechanisms would be more secure and convenient.

Durable Material

Ensure that your diamond crystals are protected with rims or plating, especially if they are situated near other pieces of jewelry, as they can scratch your other gemstones due to their superior hardness. They should be placed in secure settings such as four or six prong metal or a jump ring to secure them on your stud earrings. 

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

Good Reviews and Ratings

If you were to be meticulous in choosing your products before buying them, you would read reviews from verified purchasers who’ve already seen the product first-hand. You can assess noteworthy features and what makes diamond stud earrings worth your money through their testimonials. 

Within Your Budget

FAQs – Frequently Asked Questions

How can I care for my diamond stud earrings?

Proper and secure storage should be observed to ensure your earrings’ safety when they’re not used. It will also protect them from long exposures to some elements that can tarnish their metal material. You can also avoid exposing them to liquids or chemicals that may result in an unwanted reaction that would wear your diamond studs faster.

How can you effectively test synthetic diamonds from genuine ones?

You must remember that lab-created or synthetic diamonds can be classified as genuine diamonds too. They are designed with the same structure as natural diamonds. However, naturally occurring diamonds can still be distinguished from synthetic ones through a couple of tests that make them more valuable. 

Thermal conductivity tests work for differentiating cubic zirconia, a diamond simulant, from a naturally occurring diamond. However, moissanite, a new diamond simulant, can only be differentiated with a natural diamond using electrical conductivity tests. Diamonds have the hardest bonding pattern making them the hardest mineral in the Mohs Scale of hardness. Only a naturally occurring genuine diamond can scratch another natural diamond.

Are diamonds a good investment?

Yes. Precious metals and stones such as diamonds increase in value through time. With the depletion of their raw materials on the Earth, they become rarer and harder to 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, diamonds would also make a good investment given for your loved ones. You would want to establish a good relationship with them and appreciate how you send them a message that they are valuable and a precious investment for you.

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.
