Stones & Materials
We offer:
- Lab-grown diamonds (recommended)
- Natural diamonds (by request)
- Pink, champagne, and blue fancy lab-grown stones
- Aquamarine & colored gemstones
- Teal and blue stones in curated hues
Every stone is carefully inspected for brilliance, clarity, and sparkle.
Yes. Chemically, physically, and optically identical to mined diamonds — just ethically grown and more affordable.
They test as real diamonds and come with gemologist certification (0.7 ct+).
Due to their small size, melee diamonds (small accent diamonds typically under 0.01 carat each) do not come with individual gemologist certificates. However, any ECJ jewelry piece that contains a total diamond weight over 0.10 ct includes a Diatrue Diamond Scan Certificate.
We use the Diatrue Diamond Scanner, an advanced diamond-detection machine that accurately identifies natural diamonds, lab-grown diamonds, moissanite, and cubic zirconia (CZ). This ensures complete transparency and gives you confidence in exactly what you are receiving.
All jewelry is crafted in 14k,18k solid gold using SCS-certified recycled precious metals from United PM (Thailand) and Stuller (USA).
We can provide it upon request, but we encourage customers to choose lab-grown diamonds for long-term durability, value, and authenticity.
