Marquise diamonds are having a moment. This historic shape is one of the “spreadiest” options, because its tapered ends create more surface area.
When choosing between marquise, you will want to consider the ratio of each stone. A lower ratio means a shorter and wider stone; a higher ratio means a thinner and longer stone.
You should also check that a “bow tie” is not overly prominent. Due to its elongated shape, most marquise will have some degree of a bow tie in their center, but if the bow tie is too dark and wide, it will detract from the overall look of the stone.
The pointed tips of the marquise, although beautiful, are the diamond’s most vulnerable points. Consider choosing a setting that covers both tips with secure prongs.
No matter what shape of diamond you’re looking at, these are a few other considerations to take into account:
- Who certified the diamond? Some companies sell diamonds that were graded by in-house gemologists; we strongly believe it is best if a diamond is graded by a third-party lab such as GIA, IGI, or GCAL. GIA tends to have stricter standards than the other two labs. This does not mean non-GIA graded diamonds are undesirable, but rather it just means you may not be comparing apples to apples if you’re looking at stones graded by different labs.
- Are any inclusions visible to the eye? In diamonds with VS2, SI1 and SI2 (and below) clarity grades, there may be small imperfections that are visible without a loupe. The details of those inclusions matter. if they’re in a corner that can be covered by a prong, for example, or if the inclusion is a white feather, it won’t impact the final look of your ring and that stone is likely a great buy.
- Is there fluorescence present? Generally with higher colors, it is better to have less fluorescence, because fluorescence often results in a less lively stone. However, fluorescence can also help warmer colors look whiter on their face.
- How is the symmetry and polish graded? A top grade on both will contribute towards the diamond’s overall brilliance and shine.
