Imperial Topaz, Brazil.
The stone
When people think of topaz they think of an inexpensive blue stone. That is ordinary topaz. Imperial topaz is something else entirely — and one of the rarest gemstones in the world.
Its warm orange, shot through with pink and peach, is unique. The finest examples shift colour in the light in a way that recalls a sunset. And it is traded entirely untreated.
Origins
- Ouro Preto (Brazil)
- The historic gold-rush town in Minas Gerais is the only relevant source. The mines are small, worked by hand, and yield limited quantities. No industrial extraction, no large reserves in waiting.
- The colour range
- The most coveted colours run from warm sherry orange through salmon and peach to a rare, intense pink-orange — “imperial pink”, which commands the highest prices.
Imperial Topaz as an investment
Imperial topaz is a niche market with potential. Appreciation runs at 4 to 7 per cent a year and is trending upward as awareness among collectors grows.
- Only one relevant source worldwide
- No industrial mining; annual production is limited
- Still moderate prices compared with the great four
- Entirely untreated — no treatment discussion at all
- Growing recognition at international auction
- Its low profile is the opportunity
Quality criteria
- Colour
- Intense orange-pink through to imperial pink commands the highest prices. Pale yellow-orange is worth considerably less; saturation makes the difference.
- Origin
- Practically always Ouro Preto. Other origins are extremely rare and not relevant for investment.
- Clarity
- Imperial topaz is often very clean. Eye-clean is the standard; included stones are of little interest for investment.
- Treatment
- A significant advantage: imperial topaz is almost never treated. Irradiation and heating do not occur in genuine material.
- Size
- Above 5 carats in fine colour it becomes interesting. Stones above 10 carats in imperial pink are decidedly rare.
- Certificate
- GIA, Gübelin or SSEF. An origin report is advisable, even though the source is effectively unambiguous.
