What is the best cut or shape for Montana sapphire?

Montana Sapphires: Choosing the Right Shape and Cut

Montana sapphires are prized gemstones found in various colors, from blue to green, pink, and yellow. When it comes to buying a Montana sapphire, one of the most frequently asked questions is, “What is the best cut or shape for Montana sapphire?” In this article, we’ll explore some key considerations when choosing the right shape and cut for your Montana sapphire.

Shape: A Personal Preference

The shape is one of the most important considerations when selecting a sapphire. Most buyers express shape preferences before anything else and often before seeing any stones. Decisions about color, clarity, and size are usually not finalized until after they have examined a number of gemstones. The shape must be both fundamentally important and personal.

There is no one “best” shape for Montana sapphire or any sapphire from any other source. The best shape in each case must be the one each buyer is drawn to for known and unknown reasons. Some people prefer curved shapes like round brilliants, ovals, and trillions, while others prefer straight lines like emeralds, hexagons, and princess shapes. Some people like brilliance and a lot of sparkle, while others prefer a more laid-back, softer, and more restful look.

Rough Shape Variance

It is fortuitous that different people have different shape preferences because rough sapphires mined in Montana, like sapphires mined elsewhere, do not all have the same shape. Sapphires have a definite shape (hexagonal) when they are formed. However, in the interval between being formed and mined, they are subjected to a great many geological events. Some of these events cause almost all sapphires to be broken into fragments. They are often broken to such an extent that their original crystal structure is not recognizable. Consequently, some are relatively flat; others are round or elongated with either blunt or pointed ends.

This means that every rough crystal will not be cut into the same shape. Each rough stone will be preformed and cut into the shape that either creates the best-looking stone and/or the most polished weight. Consequently, a variety of shapes are produced, and as mentioned earlier, this is fortuitous because not everyone wants the same shape.

Cut Quality: The Key to Beauty

Cut quality is a function of lapidary skill and the will to apply it. Unfortunately, commercial considerations usually trump the will to apply the skill to produce a quality cut. The principal commercial consideration is that quality cutting usually sacrifices weight. The average consumer is more influenced by weight than cut quality because the former is more transparent than the latter. It is for these reasons that, given a choice, sellers most often will choose weight retention over quality cutting.

However, the beauty of any shape will depend on the quality of the cut. This is where the true value of a Montana sapphire lies. The best value is acquired when the sapphire reflects the best cutting, regardless of its shape or size.

Conflicting Preferences

Shape preferences can sometimes conflict with other preferences. For instance, someone who prefers a round shape and a darker tone color may find that the appeal of the round brilliant is often the brilliance, liveliness, and scintillation that the round shape produces. Unfortunately, the darker the tone of the color, the less brilliant the stone will be. The difference can be very noticeable. Diamonds are one of the most brilliant gemstones, but black diamonds have no brilliance. The same is true of sapphires, including those mined in Montana.

Cut vs. Shape

Sometimes, people use cut to refer to shape, and at other times, they use the word to refer to the process of changing a rough stone into a finished, polished, and marketable gemstone. When the word is used in this latter sense, the issues and concerns involve quality, as in the quality of the cut, and sometimes this can be what is intended in the question, “What is the best cut in sapphires?” This can be a complicated topic and deserves a discussion on its own.


Montana sapphires are unique and valuable gemstones that come in various colors and shapes. When choosing the right shape and cut for your Montana sapphire, it’s important to consider your personal preferences, the quality of the cut, and the overall value of the gemstone. To get the most out of your Montana sapphire, it’s essential to choose a seller who recognizes and values the importance of quality cutting. With these considerations in mind, you’ll be able to find the perfect Montana sapphire that matches your preferences and style.
