The World of Blue Gemstone Jewelry

We believe sapphire is the best everyday choice. It comes in a wide range of sizes, shapes, and price points, and with reasonable care it can be worn daily and still look wonderful fifty or even a hundred years from now. Aquamarine isn't recommended for a ring you'll wear every day since it's softer and more prone to scratch. Blue topaz makes a lovely ring for every day, casual style, though it doesn't carry quite the same formal, classic feel as sapphire.

Blue topaz can be mixed with other colors, paired with citrine or blended with amethyst, and worn to pick up the colors already in an outfit. It is easy to wear, because it can be styled for everyday or a memorable pop of color.

Blue sapphire, on the other hand, works almost like a neutral, the jewelry equivalent of a little black dress, so a navy sapphire piece goes with nearly everything and isn't limited to being worn with other sapphire. Sapphires can be found in studs, eternity bands, flexible bracelets and dramatic necklaces.

The answer is all of them. White gold and platinum enhance crisp, cool blue tones, while yellow gold creates warmth and contrast.

Blue topaz is our best seller by volume. Its price point makes it an easy, versatile choice, and it comes in three distinct shades, sky, Swiss, and London Blue. Sapphire is where EFG Designs has built its reputation. We've worked with ruby, sapphire, and emerald for decades, and sapphire remains the stone people trust us to get right, whether that's a first pair of earrings or a serious engagement ring.

Almost all sapphire has been heat-treated, a practice going back thousands of years that brings out a richer, more even blue and doesn't affect the stone's durability and does not require special care. It's a completely standard, disclosed practice in the trade. Sapphires that do not have heat treatment are rare.

Look for color that is evenly distributed throughout the stone, not just in one area.

Topaz occurs naturally in a number of colors, but the vivid blues we sell, Swiss, sky, and London Blue, are achieved through a safe, government-regulated process of heating and irradiation. It's a well-established, completely standard practice in the industry, similar to how the great majority of sapphires are heat-treated to bring out their finest color.

Sapphire comes in nearly every color except red: deep navy, medium and pale blues, and rarer yellow, pink, green, and purple tones. Within blue alone there's real variation. Some stones show an even, uniform color, while others display natural banding, called color zoning, that's worth looking for when you're comparing stones.

Sapphire rainbow jewelry uses the full range of natural sapphire colors together in a single piece, not just blue. It was especially popular in years past and remains a beautiful, if less common, style today. Typically from dark blue through to pink.

Yes, and it's one of the things we love doing most. A sapphire ring or aquamarine pendant that's been sitting in a drawer for years can usually be reset into something you'll actually reach for, while keeping the stone that made it meaningful in the first place. If you have a blue gemstone piece you've inherited or outgrown, reach out and we can talk through what's possible.
