Gemstones

Sapphire (Mohs 9) and ruby (also corundum, Mohs 9) are the most popular durable choices for daily-wear rings. Spinel (Mohs 8) and moissanite (Mohs 9.25) also hold up well. Emerald (Mohs 7.5–8) is beautiful but often included and can be brittle—protect it in a bezel or halo setting. Softer gems like opal, pearl, and tanzanite are better suited to earrings, pendants, or occasional-wear rings. We match stone choice to how you actually use your hands.

Most colored gems on the market have been enhanced in some way. Heat treatment is standard for sapphires and rubies and is widely accepted when disclosed. Emeralds are often oiled to improve clarity appearance. Other treatments—irradiation, diffusion, fracture filling—vary in stability and value impact. A reputable seller always discloses treatments. We explain what you are buying, how it affects long-term care, and how it compares to untreated stones at a similar price point.

Unlike diamonds, there is no single universal grading scale for every gem species. We evaluate hue (the color itself), tone (how light or dark), and saturation (intensity of color)—the three components of color quality. Clarity, cut, and carat weight matter too, but the right balance depends on the gem: a slightly included emerald can still be stunning if the color is exceptional. Origin (Kashmir sapphire, Colombian emerald) can add premium value but is not the only path to a beautiful stone.

Not at all. Sapphire is corundum in every color except red—red corundum is ruby. You will find sapphires in pink, yellow, green, purple, orange, and colorless ("white sapphire"). Padparadscha sapphires—a rare pink-orange blend—are among the most sought-after. Parti sapphires show two or more colors in a single stone. Blue remains the classic, but fancy-color sapphires offer personality at a wide range of price points.

Emeralds form with natural inclusions—often called jardin (French for garden)—that give each stone character but can also create internal stress. Many emeralds are treated with oil or resin to minimize the appearance of fractures. Ultrasonic cleaners, steam, and harsh chemicals can strip these fillers or worsen existing fractures. Clean emeralds gently with warm water, mild soap, and a soft brush. Choose protective settings (bezel, halo) for rings you will wear daily.

For certain gems, yes—origin can affect rarity and price. A Kashmir sapphire, Burmese ruby, or Colombian emerald carries provenance premiums when verified by a lab. But origin is not the whole story: a beautifully cut, richly colored stone from a lesser-known source can outperform a famous-origin gem with mediocre color. We help you weigh origin against the visual qualities you will actually see on your hand.

Lab-grown gems—synthetic corundum, emerald, alexandrite, and others—have the same chemical composition as their natural counterparts but are created in a controlled environment. They are typically more affordable and free of the ethical sourcing concerns some buyers worry about with certain natural origins. They lack the geological rarity of natural stones, which matters to some collectors and not at all to others. We carry both and can help you compare options side by side.

For significant purchases—especially untreated stones, high-value rubies and sapphires, or gems where origin matters—a report from GIA, Gübelin, AGL, or GRS provides independent verification of species, treatment, and sometimes origin. For smaller accent stones or fashion jewelry, a report may not be necessary. We provide documentation appropriate to the stone and are always transparent about what has and has not been tested.

Absolutely—birthstone engagement rings are increasingly popular and deeply personal. Harder birthstones (sapphire for September, ruby for July, spinel as an August alternative) work well in daily-wear rings. Softer birthstones (pearl for June, opal for October) are better in pendants or earrings, or in rings reserved for special occasions. We can help you find a birthstone that fits both the sentiment and the setting style you have in mind.

Yes, but differently. Colored stones are often cut to maximize color rather than brilliance—a shallow cut can make a sapphire look lighter; a deep cut can darken it. Windowing (a see-through patch in the center) means light leaks out instead of returning color to your eye. Well-cut gems show even color face-up and hold their hue from multiple angles. Always view colored stones in person or via video under different lighting before deciding.
