The Ultimate Lab-Grown Engagament Ring Guide

At Charles & Colvard®, we believe your love story deserves a ring that reflects your commitment and values. Our Caydia® lab-grown diamonds and Forever One™ moissanite offer stunning brilliance, sustainable sourcing, and exceptional quality—without the environmental or ethical concerns of mined diamonds. This guide will help you find the perfect engagement ring while highlighting all the benefits of lab-grown jewelry.

Why Choose Lab-Grown Diamonds & Moissanite?

  • ETHICALLY SOURCED:
    No mining means no environmental destruction or human rights concerns.

  • EXCEPTIONAL VALUE:
    Enjoy a larger, more brilliant gem, no matter your budget.

  • SUSTAINABLY MADE:
    Our gems are created in controlled environments with minimal environmental impact.

  • UNPARALLELED BEAUTY:
    Lab-grown diamonds are chemically, optically, and physically the same as mined diamonds; the only difference is their origin. With a high refractive index of 2.65, moissanite is the world’s most brilliant gem™.
