DECIDE HOW MUCH YOU WANT TO SPEND
To make the process easier have a price range in mind before you start to shop. Going in with fairly specific parameters will help your jeweller find the right engagement ring to fit your budget.
DO YOUR HOMEWORK
Before you even set foot in a jewelry store there is a lot to learn about diamonds. A good place to start is with the 4Cs – Color, Clarity, Cut and Carat Weight – so you understand how each influences the value of the diamond and adds to the overall appearance of the stone. In doing this you can decide which is the most important to you.
UNDERSTAND HER TASTE IN JEWELleRY
If you pay attention to the kind of jewellery she already wears it could go a long way in helping you pick out the perfect ring. Does she wear more white metals or yellow gold? Do her pieces tend to be more delicate or chunky? Sleek or ornate? Have these preferences in mind when you set out to shop. If you buy something similar to what she already likes, you can't go wrong.
KNOW HER RING SIZE
If she wears rings, borrow one she already owns. Trace the inner circle on a piece of paper, or press the ring into a bar of soap for an impression. You can also slide it down one of your own fingers and draw a line where it stops. A jeweller can use these measurements to identify her approximate ring size.
If she doesn't wear rings you can estimate in the following manner: The average ring size in Canada is 6 (based on the 'average' Canadian female being 5'4" tall and weighing 140 lbs.) If she's more slender, or fine-boned, her ring size is probably in the 4 1/2 to 5 1/2 range. If she is heavier, larger-boned or taller, her ring size is probably in the 6 1/2 to 7 1/2 range. It's always better to buy a ring a bit bigger than you think she'll need, because sizing a ring down is much easier than increasing its size.
KNOW HER FAVORITE SHAPE AND CUTTING STYLE
If she hasn't made it easy for you by already voicing an opinion or showing you a picture in online, in a magazine (or admiring someone else's engagement ring), keep these thoughts in mind when considering shape.
She will be wearing the ring every day of your married life. She will want it to go with everything from jeans to evening wear. If you're uncertain about her diamond shape preference, it's sensible to stick to the classics, such as a round or square shape. They became classics because they are the most popular for most people.
Certain shapes pair more successfully with other shapes in multi-stone rings. Round, oval and marquise shapes work well sitting side-by-side. Pear and heart shapes are more challenging.
