What is a diamond?

Diamonds are crystals comprised of carbon atoms arranged in a cubic matrix. As diamonds grow, they usually encounter some heat, pressure, and other elements, all of which can alter what would otherwise be a perfectly octahedral shape. How the crystal withstands these forces determines its color, clarity, and shape.

Should I buy from a diamond warehouse that does not offer certification?

A diamond certificate is legal proof that a diamond has been inspected by a professional and verified to have the level of quality the retailer claims. Uncertified diamonds are not necessarily inferior to certified diamonds, but without a certificate, you have no way of knowing the diamond's cut, color, clarity, and carat weight with certainty. Most diamond experts advise consumers to buy from retailers that offer certificates from the GIA or AGS.

Is it safe to buy from an online diamond warehouse?

The diamond warehouse from which you buy should offer a secure and encrypted ordering process, as with any online retailer. Also pay particular attention to how the retailer ships your diamond. The retailer should use an insured carrier for its packages and should insure every shipment for its full value. A good diamond seller will explain their shipment and insurance policies somewhere on their site.

What determines a diamond's value?

Carat weight plays a major role in determining a diamond's price, but color, clarity, and cut also affect the stone's value. The most expensive diamonds are large, clear, colorless, and cut to maximize brilliance. Diamonds that meet these criteria are rare, which is why they tend to be more expensive.

Should I purchase the largest carat weight diamond that I can afford?

Buying the largest diamond that your budget allows isn't always advisable. For one, a large diamond may not suit the preferences or lifestyle of the intended wearer. Some people may prefer smaller stones. Secondly, the bone structure of the wearer is also an important consideration. If the wearer of the diamond has a slight build, a massive stone will look gaudy and out of place. Your diamond warehouse can advise you further on the ideal carat weight for your diamond.

How much should I spend on a diamond engagement ring?

The rule of thumb is to spend one to two month's salary on the ring. This guideline originated from diamond company De Beers' marketing campaign.
