Topaz Buying Guide - What Factors to Look Out For When Shopping

Color

When it comes to colored gemstones, color takes center stage in determining value, and topaz is no exception. In its natural form, topaz often appears colorless, pale yellow, or brown, but it occurs in a broad spectrum of hues. The blue varieties - think London Blue, Swiss Blue, and Sky Blue - are the most widespread and beloved, thanks to enhancement processes. On the pricier side, the warm golden tones of Imperial Topaz stand out as the premium option. And hey, if you're after a budget-friendly alternative to diamonds, clear topaz fits the bill nicely.

Clarity

Most cut and polished topaz gems achieve at least eye-clean status, meaning no obvious inclusions or flaws show up to the naked eye. Given its abundance and low cost, there's really no reason to settle for anything less than top-notch clarity. That said, untreated Imperial Topaz might have some internal features, but its scarcity keeps it highly prized regardless.

Carat

Topaz ranks among the largest gemstones commonly available, with pieces exceeding 5 or 10 carats being standard and surprisingly affordable. Aside from the elusive Imperial Topaz, the cost per carat stays fairly consistent, even as sizes increase.

Cut and Shape

No matter the color, topaz appears in every standard gem shape imaginable - from ovals, rounds, and pears to intricate carvings. Steady supplies and generous sizes allow cutters to experiment freely, often prioritizing the desired form over material conservation.

Jewelry Uses

Topaz checks nearly every box for jewelry applications: vibrant hues, diverse cuts and shapes, strong durability, and plentiful large sizes. It's especially suited for standout pieces like bold pendants or eye-catching brooches, though it works well in rings, earrings, and more.

Treatments

Techniques like heating and irradiation have propelled blue topaz varieties - Sky Blue, London Blue, and Swiss Blue - into global popularity. These methods ensure a reliable supply and uniform colors that jewelers can count on.

Price

Even with its impressive appearance, topaz remains one of the most budget-friendly gemstones out there. High-quality blue, pink, and white specimens come at modest prices, while Imperial Topaz commands a higher premium due to its rarity.

Birthstone

Topaz serves as the official birthstone for November, with blue topaz also acting as an alternate for December birthdays.

Wedding Gemstone

Tradition calls for topaz as a gift on the 4th wedding anniversary, while Imperial Topaz marks the 23rd milestone.

Durability

With a rating of 8 on the Mohs hardness scale, topaz offers excellent resistance to scratches and wear, making it a solid pick for daily jewelry.

Summary

Overall, topaz delivers great value as a widely available and cost-effective gem. For the best bang for your buck, go for a vivid blue stone with flawless clarity, weighing at least 4 or 5 carats, in shapes like oval, round, or pear. If you're aiming for something truly showstopping, consider a massive 20- or 30-carat piece - or larger - for an unforgettable pendant.
