- Size does matter
A round brilliant cut will give the best sparkle however they are expensive. A princess cut diamond gives a good balance of brilliant sparkle and cheaper costs as it even looks bigger than a round brilliant cut of the same carat.
- Be shy of whole numbers
Carat is the metric system for measuring gemstones weight. Higher carat equals greater weight and size. Choose carats according to your requirement. Keep in mind that every jump in the carat rating to a whole number or an exact half entails a significant jump in the costs as well, so buy shy of a full carat or an exact half.
- Acceptable imperfections
Normally earrings do not come under close scrutiny as would a ring and it is quite acceptable to have lower clarity ratings for them. Remember clarity ratings do not affect the sparkle as well but bear in mind that inclusions can weaken diamonds so do not go too low.
- Get her a Stud
The all time best selling diamond earring is the stud diamond earring style. If you are buying diamond earrings as a gift and uncertain of which type to get, sticking to the classic style is your safest bet. Better still observe the kind of earrings she prefers to wear and buy a diamond earring of that type of style.
- Trust but verify
Always make sure the diamonds for your earrings come with a report document and it is recommended to get your diamonds appraised by an independent appraiser. Also ask for a return policy and understand the terms in it.
- Metal gear
Recommended earring metals for diamonds are platinum or white gold as they compliment the diamonds and make them seemingly larger. Some people are allergic to white gold due to the nickel alloy usually present in 14K white gold. Silver metal is also a good choice for earrings but fine or pure silver (99.99 %) rather than sterling silver is recommend as some people can develop an allergic reaction to the alloy in sterling silver.
- Diamonds and rust
Well, diamonds don’t rust thankfully but they do get dirty and they need to be cleaned to maintain their sparkle. Also diamonds can scratch each other and this is a common issue with diamond earrings as they usually are kept together. Therefore when you buy diamond earrings, be sure to ask and learn how to care, clean and store them properly.
