Natural Emerald Rings
Natural emerald rings go through no process to alter the quality of the natural emerald stone. These are the most rare emerald rings, and most valuable.
Heat Treated Emerald Rings
Jewelers often heat emeralds to enhance their appearance to the naked eye. These are heat treated emerald rings and are not as valuable as natural emerald rings.
Diffusion Treated Emerald Rings
Diffusion is a step further than heat treated. Diffused emerald rings are typically heat treated first, and then enhanced with another mineral.
Lab Created Emerald Rings
Lab created, or synthetic, emerald rings are exactly that, not natural. The emeralds are grown in labs over a certain period of time. This process is not inexpensive (it might knock half the price off the retail cost of a middle of the road emerald ring), but the resale value is typically very low.
