Lab‑Grown vs Natural: Your Choice, Your Values
Lab‑Grown Diamonds
- Real diamonds grown with advanced technology (same crystal structure and brilliance).
- Often priced lower for comparable size and quality.
- Reliable traceability and modern, innovative appeal.
Natural Diamonds
- Formed over billions of years—each stone is a one‑of‑a‑kind timepiece of nature.
- Enduring tradition with global desirability.
- Responsibly sourced through vetted supply chains.
Diamond Education: The 4Cs
Cut
The most important C for sparkle. Excellent/Ideal cuts maximize brilliance and fire.
Color
Near‑colorless (G–J) offers great value; D–F is icy white. Match to metal tone and preference.
Clarity
VS–SI stones often appear eye‑clean. Focus on how the diamond looks, not just the grade.
Carat
Size affects presence and price. Balance with cut quality for the best overall beauty.
Shapes
Round, oval, emerald, cushion, pear, marquise, radiant, princess and more—each brings a unique personality.
Metals
18k yellow, white, or rose gold, and platinum. We also offer recycled precious metals upon request.
Certification
Every center stone ships with an independent grading report from respected laboratories.
