At Octa Pearl, we specialize in high-quality lab-created stones such as moissanite and cubic zirconia (CZ). However, for custom requests, we also offer a limited selection of certified natural and lab-grown diamonds through partnerships with trusted organizations like the Asian Gem Society Laboratories (AGSL).
Founded in 1978, AGSL is a respected gemological laboratory known for promoting consumer protection and diamond grading standards. Their certification process rigorously evaluates each diamond based on the “4 Cs”: Cut, Color, Clarity, and Carat weight.
Cut: AGSL evaluates every diamond's proportions, symmetry, and light performance to ensure maximum brilliance.
Color: Each stone is graded under standardized lighting to determine its exact color on the official diamond scale.
Clarity: High-powered microscopes are used to identify any internal or surface imperfections that may affect the stone’s beauty or value.
When requested, Octa Pearl works with AGSL-certified stones to offer custom engagement rings and fine jewelry with full transparency. Explore our engagement ring collection.
Certified diamonds give you peace of mind. Every AGSL-certified diamond is accompanied by a detailed grading report, helping you make a confident, informed purchase.
Whether you choose moissanite, CZ, or a certified diamond, you can trust Octa Pearl for craftsmanship, ethical sourcing, and lasting brilliance.
If you have questions about certification, sourcing, or custom designs, please contact us. We’re here to help you find your perfect piece.
