Q: Can gemstones get scratched?

Yes, some gemstones are more durable than others. For everyday wear, we recommend stones with a high hardness rating. Diamonds, moissanite, sapphires, rubies, topaz, aquamarine, and morganite can withstand frequent wear without worry. Amethyst, garnet, and tanzanite are beautiful, but they deserve more careful handling. We recommend moonstone and opal for occasional wear.

Q: Which gemstone to choose for an engagement ring?

Most people choose a diamond, sapphire, or moissanite. A diamond is a timeless classic, a sapphire stands out for its color and elegance, and moissanite offers a striking sparkle at a more affordable price. These stones are also among the most durable. However, you can choose any gemstone from our selection. With proper care, most stones can withstand daily wear; we only recommend extra caution with softer stones.

Q: How to properly care for a ring with a gemstone?

To keep your jewelry beautiful for a long time, clean it regularly with lukewarm water and a drop of dish soap, then wipe it dry with a soft cloth. Be sure to remove it before showering, exercising, gardening, or coming into contact with chemicals (creams, perfumes, detergents). Ideally, put it on as the last thing before leaving the house and take it off again upon your return.

Q: What is the difference between natural and lab-grown gemstones?

The main difference lies in their origin and price. Natural gemstones form in the Earth's crust, while lab-grown gemstones are created in a laboratory. Both types have the same chemical composition and physical properties, making them virtually indistinguishable. While lab-grown stones tend to be more affordable, they fully match natural stones in terms of quality, durability, and beauty.

Q: Moissanite vs. Diamond – How do they differ?

Moissanite is a genuine gemstone, not a diamond imitation. With a hardness of 9.25 and a high refractive index, it sparkles brilliantly and closely resembles a diamond at first glance. However, moissanite is distinguished by its characteristic iridescent flashes. It is produced exclusively in a laboratory, is significantly more affordable, and is therefore a popular alternative to diamonds.

Q: What is a salt & pepper diamond?

Salt & pepper diamonds are natural diamonds with visible inclusions – dark and light imperfections that resemble salt and pepper. Each stone is completely unique. These gemstones are prized for their unique, raw appearance, offering an interesting alternative to traditional clear diamonds. They retain the full hardness and durability of a diamond, often at a more affordable price.

Q: Sapphire vs. Moissanite – How to Choose?

Both gemstones are very durable and suitable for everyday wear. Sapphire stands out for its color and depth of hue; you'll most often find it in blue, but it also comes in pink, yellow, or colorless varieties. Moissanite, on the other hand, is known for its intense sparkle and colorless appearance, reminiscent of a diamond.

Q: Why do gemstone prices vary so much?

The price of gemstones depends on several factors — in particular size (carats), color, clarity, cut quality, and origin. For natural gemstones, rarity also plays a major role, which is why some types are significantly more expensive.

Q: Are lab-grown gemstones cheaper, and why?

Yes, lab-grown gemstones tend to be more affordable because their creation is controlled and does not depend on natural conditions or limited resources.
