Most blue sapphires on the market today are natural gemstones that have undergone heat treatment, a widely accepted industry practice. This process involves exposing the sapphire to high temperatures to enhance its color and clarity, mimicking the natural conditions under which sapphires form deep within the earth. Heat treatment is considered permanent and stable, and it does not require any special care beyond whats recommended for untreated sapphires. It is important to note that heat treatment is not considered deceptive -- reputable jewelers disclose it and consumers recognize it as a standard enhancement that adds beauty and value.

In contrast, untreated blue sapphires -- those that have not undergone any enhancements -- are extremely rare and often command significantly higher prices due to their natural, unaltered state. For collectors and purists, untreated sapphires may hold additional appeal, but they are not necessarily more durable or better suited for daily wear than their heat-treated counterparts. In fact, the vast majority of fine-quality sapphires seen in engagement rings and high-end jewelry are heat treated, offering vibrant color and excellent clarity at a more accessible price point.

There are, however, other treatments beyond heating that are sometimes applied to sapphires -- and buyers should be cautious about these. Diffusion treatment, for example, involves adding coloring agents like beryllium or titanium during heating to artificially alter the sapphire's color. This process often results in surface-level color that doesnt extend throughout the stone, and the effect may not be permanent. Such sapphires are often less valuable, and diffusion treatment is not widely accepted in the fine jewelry industry. At MyJewelrySource, we do not use diffusion-treated sapphires we are committed to offering only traditionally heat-treated or untreated stones with full disclosure.

When choosing a sapphire, color is the most important factor. Blue sapphires come in a range of hues, from the palest baby or periwinkle blue to the deepest darkest navy blue. Sapphires actually are found in every color of the rainbow. The most prized stones often have a velvety or royal blue color with strong saturation and excellent transparency. Pale or overly dark sapphires tend to be less valuable. What matters most, though, is that the color appeals to you -- beauty is personal, and each sapphire is unique.

Clarity is also a consideration, though not as strict as it is with diamonds. Most sapphires have some natural inclusions, and these are generally acceptable as long as they dont affect the gems beauty or durability. At MyJewelrySource.com, we focus on offering sapphires that are eye-clean and nearly loupe clean in most cases; inclusions aren't visible without magnification. A clean appearance enhances the stones brilliance and overall appeal.

Next is cut, which greatly impacts how lively the sapphire appears. While diamonds are cut to precise standards, sapphires are typically cut to maximize color and retain carat weight. A well-cut sapphire will reflect light evenly across the surface, without windows (dull areas) or overly deep pavilions. Look for symmetrical outlines and good proportions -- even if the gem isnt perfectly calibrated. In short, the cut should showcase the color beautifully and create a pleasing sparkle.

Carat weight affects price significantly, but its not just about size. Sapphires over 1 carat are considered important, and as size increases, prices rise steeply -- especially if the quality is high. When choosing the right size, think about your lifestyle, budget, and preferences. Some clients prefer a bold, statement piece; others value practicality or subtle elegance. The best investment is one that balances beauty, wearability, and personal significance to you.

You'll also want to consider whether the sapphire has been treated. The vast majority of sapphires are heat treated to improve their color and clarity a permanent and widely accepted enhancement. However, you should avoid sapphires that have been diffusion treated or filled, as these are less stable and much lower in value. At MyJewelrySource.com, we fully disclose any treatments and only offer stones that meet high standards for authenticity, durability, and long-term beauty.

Finally, choosing the right sapphire comes down to your priorities. Are you drawn to a specific color hue? Do you prefer classic or modern settings? Are you shopping for a symbolic occasion or just because you love beautiful jewelry? Sapphires are incredibly versatile, durable, and meaningful -- whether you're buying a ring to wear every day or a once-in-a-lifetime gift. When you choose a sapphire that speaks to your heart and fits your lifestyle, youll treasure it for years to come.

Blue sapphires are incredibly stable and do not fade over time under normal wear and care. Unlike lower-quality gems or heavily treated stones, natural sapphires especially those that are heat-treated only retain their color and brilliance for a lifetime. They are resistant to light, heat, and most environmental factors, which makes them an ideal choice for everyday wear. You can confidently wear a blue sapphire ring daily without worrying that its color will dull or wash out.

That said, extremely rare exceptions do exist. Some low-quality or artificially treated sapphires, such as those altered with irradiation or certain types of diffusion, may not be fully stable and could show color changes over time. These are not the types of sapphires we offer. The sapphires at MyJewelrySource.com are either untreated or traditionally heat-treated, and are selected specifically for their long-term beauty and durability.

Sapphires also do not become cloudy over time unless they accumulate residue from daily wear. Buildup from hand lotion, soap, or hard water can temporarily dull a sapphires surface, giving it a hazy or cloudy appearance. This is easily resolved with gentle cleaning using warm water, mild soap, and a soft brush. With minimal maintenance, your sapphire will remain bright, clean, and beautiful for generations to come.
