FREQUENTLY ASKED QUESTIONS

Why are one-carat rubies considered an ideal investment size?

One-carat rubies represent an ideal investment threshold where the stone achieves substantial visual presence while remaining within a more accessible price range than larger specimens. These natural precious stones have historically maintained strong value retention, particularly flawless examples from prestigious mining regions. The purchase of a high-quality 1 ct ruby often marks a significant milestone for serious gemstone collectors.

How does color affect the worth of a 1 ct ruby?

Color is the primary value determinant for a 1 ct ruby, with vivid “pigeon’s blood” red commanding premium prices in the market. Natural color variations with purple or pink undertones affect worth significantly, with the most desirable being pure red with exceptional saturation. The cost of conflict-free one-carat rubies can vary dramatically based solely on subtle color distinctions visible to the trained eye.

What certification should accompany quality 1 carat rubies?

Quality one-carat rubies should be accompanied by respected laboratory certification like GIA or Gübelin that verifies origin, treatments, and natural status. These certificates provide crucial authentication of the stone’s genuine character and conflict-free provenance. The documentation serves as an essential component of the ruby’s value, particularly for investment-grade stones where origin often impacts price substantially.

Which shapes are most popular for 1 carat ruby gemstones?

Oval and cushion shapes remain the most popular choices for 1 ct ruby gemstones as they optimize the stone’s color while preserving carat weight. These classic cuts enhance the natural beauty of the precious stone while providing versatility for various jewelry settings. The aesthetic appeal of these shapes has remained consistent throughout jewelry history, making them excellent choices for both contemporary designs and future resale value.
