Buying guide

Independent certification ensures that the diamond you're buying is of good quality and has been precisely graded without any bias. At Amour, all our diamonds are graded and checked for quality by the Gemmological Institute of America (GIA), which is one of the leading and most accurate diamond labs in the world. We encourage you to review the Diamond Grading Report or Diamond Dossier of any diamond to be sure of its quality before making a purchase. For every pendant, custom-made ring, or pair of earrings you buy from our store, you also get an appraisal that includes the item's retail replacement value that you can use to file an insurance claim.

Buying a diamond can be one of the biggest investments you will ever make in your life. Diamond certification (or diamond grading) is, therefore, extremely crucial when buying a diamond. The GIA provides two reports on any diamond they evaluate (i) the Diamond Dossier and (ii) Diamond Grading Report. Although both are similar in many ways, they have their unique differences.

• Diamond Grading Report: This report provides information about the diamond's 4 Cs, namely cut, clarity, colour, and carat. It also lets you know the shape and exact measurements of a diamond, as well as a map or plot of the stone's unique characteristics. The diamond grading report will also reveal whether the gem comes with a girdle inscription and discuss other important characteristics beyond the 4C.
• Diamond Dossier®: The diamond dossier contains almost the same information as the diamond grading report. The only difference is that it does not include the plotted diagram. The dossier also features the laser inscription number on the diamond's girdle to show that it's authentic.

Get to know the look and orientation of a Diamond Grading report from the GIA. Amour customers get a GIA grading report for every loose diamond they buy from us, but you may also download a sample below. Check the 4Cs, plotted diagram, as well as the mapping of the diamond's proportion. Each product page of each loose diamond on our website will include a GIA grading report.

Yes, it's extremely important that you get a certification when you buy a diamond. In fact, it is often called the 5th C. Buying diamonds with a GIA grading report will help you later on if you want to:

• Check your diamond's quality.
• Help to verify ownership for repair or insurance purposes.
• Be useful if you wish to resell the diamond.

You can always use our printable ring sizer to measure the size of a ring quickly. Just print out the guide and put one of the wearer's current rings over the circles, matching the shank of the ring to the circle closest to it in size. In case the ring falls between two circle sizes, select the bigger size.

Our guide also comes with a ring size chart including exact diameter measurements and their respective ring sizes, together with international ring sizes. Using our online ring sizer, you can easily and quickly find the right ring size for you or the recipient.

If you are buying a diamond for another person, the simplest and faster way to know his or her ring size is by asking. But if you want to surprise them, you can get assistance from family and friends. There are ways they can help you ask without raising suspicion. Generally, women's average ring size is between size 3 and size 9. The most commonly bought women's rings range from size 5 to size 7, while the most popular is size 6. On the other hand, men's average ring size is between size 6 and size 13. The most commonly bought women's rings range from size 8 to 10 -1/2, and The most popular is size 9. When looking to buy a ring, these standard ring sizes can assist you in making the right choice. In case you can't find the size you want, reach out to our experts for assistance placing a custom offer. That said, there are also many ways to find your ring size at home.

1. Wrap a paper or string around the base of your finger
2. Use a pen to mark where both ends meet
3. Use a ruler (mm) to measure the paper or string. Divide what you get by 3.14 (or Pi) to know the diameter of the ring
4. Choose the nearest measurement on the ring size chart to know your ring size

1. Calculate the diameter of another ring that fits you using our printable ring size or a tape measure.
2. The ring has to fit your finger perfectly. That is, it should be tight enough not to fall off but also loose enough to be easy to remove.
3. If the base of your finger is smaller than your knuckle, make sure to measure both places and choose a size that falls between the two.
4. You should measure your ring size in the evening when your fingers are not cold. Finger size varies based on the weather and the time of the day. Your fingers are smaller in the first hours of the morning and when the weather is cold. Note that the fingers on the hand you use the most are likely to be bigger.
5. Repeat the measurement 3 to 4 times for more accuracy

1. In some cases, your ring may need to be resized to get the perfect fit. The resizing process involves removing or adding a small amount of metal based on the difference between the size of the ring you buy and the new size you asked for. Therefore, your ring might be a bit thinner or thicker once it is resized. However, these changes are not usually noticeable to the naked eye.
2. The expert jewellers at Amour follow stringent quality standards to ensure that your resized ring fits well and sparkles brilliantly. Once the band is resized, the jeweller will clean and polish the ring before sending it back to you.

No worries. Amour will resize it for you free of charge as long as the wedding band or engagement ring is within the manufacturer's recommended sizing range and was bought no longer than one year ago. If you want another ring, we will also allow you to swap them within 30 days of purchase.

The design of some ring styles makes it impossible to resize them. You will find an icon on the product detail page for such rings.

Examples of rings that cannot be resized include silver rings, rings with alternative metals like Tungsten, milgrain or ornate bands, or gemstone and diamond eternity rings that have a certain number of gemstones per finger size.

At Amour, we offer a 30-day exchange policy if the ring is not the right size. Bear in mind that if you opt for a ring exchange, your new ring may or may not have the same number of diamonds, gemstones, or precious metal weight as the previous one, which can affect the price.

One of the most important factors to consider when choosing a diamond to buy is the cut. A diamond's cut does not mean the shape of the stone. It refers to the symmetry, polish, and balance of proportion achieved by the gem cutter. A diamond's cut quality determines how beautiful it is overall. The better the diamond cut, the better the diamond's ability to refract and reflect light. Today's diamond cutters have a good understanding of how light passes through diamonds and have created some ideal proportions and angles to cut a diamond to best optimize its innate brilliance.

In their natural state, diamonds look like two square pyramids that are arranged into an octahedron with eight sides. A point–cut diamond is a diamond that has been polished but still retains its natural octahedron shape. Although still attractive, this does not optimize the effects of light passing through the diamond.

A diamond's table, width and depth are the three main factors that determine its ability to reflect light properly. The light return from a diamond depends on the table size and depth of the stone in relation to the width. The proper width also ensures that light is refracted at the critical angle.

A properly cut diamond design is proportioned to ensure that most of the light that enters the stone goes back out through the crown of the diamond, creating a balance between the white light (brilliance ) and intense flashes of fire (different colours – known as dispersion).

However, if a diamond is cut even slightly out of proportion, it can cause the stone to tunnel light direct light out of the pavilion instead of redirecting it back up towards the diamond table. This phenomenon is called light leakage. The result is a dull-looking diamond with poor light performance and a dark centre that conceals the diamond's innate sparkle.
