Once you've determined what cut, color, and clarity grade you're looking for in a diamond, it's easy to determine the carat weight of diamond that will fit within your budget.
When diamonds are mined, large gems are discovered much less frequently than small ones, which makes large diamonds much more valuable. In fact, diamond prices rise exponentially with carat weight. So, a 2-carat diamond of a given quality is always worth more than two 1-carat diamonds of the same quality.
What Size is Best?
To choose the best carat weight of diamond, consider her style, the size of her finger, the size of your setting, and your budget.
If you have a set budget, explore all your options and you'll find that there is a wide range of diamond carat weights and qualities available in your price range.
If your recipient is very active or not used to wearing jewelry, she may find herself bumping or nicking her new ring. Consider a setting that protects her diamond from getting knocked against doors and counters.
Also keep in mind that the smaller the finger, the larger the diamond will appear. A 1½-carat diamond solitaire looks much larger on a size 4 finger than a size 8.
If you have already chosen a setting, make sure you choose a diamond to fit. Ask us about the diamond size specifications for your ring. Some settings can hold a variety of sizes and shapes, however some are limited to stones within a .2mm variance.
But the best way to determine what size is best is by getting an idea of what she is expecting. If you plan carefully, you can get some answers without even raising her suspicions. Make comments on other people's rings and see what she has to say. Make comments on the large number of jewellery ads you see every Christmas or Valentine's Day and listen carefully.
