Which gemstone is rarer than diamonds?

While diamonds are iconic, colored gemstones such as alexandrite, padparadscha sapphire, and Burmese ruby are significantly rarer in fine qualities.

What determines the value of a gemstone?

Value is driven by color, clarity, cut, and carat weight, along with origin, rarity, and demand in the collector market.

Are rare gemstones a good investment?

Fine untreated gemstones with strong provenance hold enduring value and often appreciate over time due to their scarcity.

How long does a bespoke jewelry commission take at Caram?

A typical Caram bespoke commission takes 8 to 14 weeks from first consultation to unveiling, depending on the gemstone selection process and design complexity.

Can I redesign an inherited piece into a bespoke jewel?

Yes. Many bespoke commissions begin with an inherited jewel. Caram assesses the existing stones, proposes a new design, and either resets or recuts the piece as required.

Do I need to choose a gemstone before starting a bespoke design?

Not always, though it usually shortens the process. The character of the gem often shapes the design. If no stone is yet in mind, Caram guides selection during the first consultation.
