FREQUENTLY ASKED QUESTIONS

Why is the one-carat threshold particularly significant in gemstone valuation?

The one-carat milestone represents a psychological benchmark where gemstones achieve undeniable presence and significance. This crucial weight threshold triggers substantial per-carat price increases – typically 20-30% over similar-quality stones just below one carat. Natural, high-quality precious stones at exactly one carat offer perfect balance between impressive size and wearable proportions, making them consistently desirable in both retail and investment markets.

How does a one-carat gemstone compare visually to smaller sizes?

One-carat gemstones command attention without overwhelming – creating approximately 50% more visual impact than 0.75 carat stones despite only 25% greater weight. Their perfect proportions achieve ideal light performance, with enough depth for optimal color saturation while maintaining face-up presence. For conflict-free, GIA-certified colored stones, this size category perfectly balances impressive aesthetics with wearable comfort for signature jewelry pieces.

What makes one-carat stones particularly desirable for investment purposes?

One-carat precious stones consistently outperform smaller sizes in long-term value appreciation, maintaining stronger demand through market fluctuations. Their perfect combination of substantial presence and wearable proportions ensures enduring desirability regardless of changing fashion trends. Natural, untreated gemstones of exceptional quality at precisely one carat represent perhaps the most liquid gemstone investment category, combining meaningful size with maximum marketability and established valuation parameters.
