At Everglow Jewelry, we believe in transparency, education, and helping you make confident, informed choices about your jewelry. Whether you're selecting a custom engagement ring, a gemstone bracelet, or heirloom redesign, understanding gemstone treatments and types is key to choosing a piece you'll love for a lifetime.
Let’s explore the different gemstone categories and common enhancements so you can shop with clarity and confidence.
💎 Natural Untreated Gemstones
What it means:
These are gemstones that are formed in nature and cut and polished without any enhancements or treatments. They are the rarest and often the most valuable because they are completely natural in color and clarity.
Examples:
• Some sapphires, emeralds, and spinels
• Natural diamonds without clarity or color treatment
Why choose it:
You're getting a rare, one-of-a-kind stone with natural beauty. These are ideal for collectors or those who value purity and origin.
💎 Natural Treated Gemstones
What it means:
These are real, natural gemstones that have undergone treatments to improve their color or clarity. Treatments may include heating, irradiation, oiling, dyeing, or fracture filling.
Common Treatments:
Heat treatment (common in rubies, sapphires, aquamarine)
The heat treatment of gems is the most common treatment technique used on gems. Reference to heat treatment of gems is found in gemological literature dating back thousands of years. However, widespread use started in the 20th century. This treatment is usually detectable in many gems. Heat treated gems are stable and the treatment is usually permanent. The vast majority of gemstones are heated to alter their color. In ruby and sapphire the treatment is often performed to improve color and clarity.
Oiling (used in emeralds to fill fractures)
Oiling refers to a filling of surface reaching cracks or fissures in a gem with a colorless oil or resin, wax or other substance except glass or plastic, to improve the gemstone’s appearance. The purpose is to diminish the visibly of fractures and thus improve transparency in the stone. The treatment is usually not permanent.
Irradiation & diffusion (used in topaz, some sapphires)
Irradiation refers to the use of neutrons, gamma, and/or electron bombardment to alter a gemstone’s color. The irradiation stage of the process is then usually followed by a heating phase to effect the change. Blue topaz is typically produced by irradiation.
Why choose it:
They're more affordable than untreated gems and often more vibrant. As long as treatments are disclosed—like we do at Everglow Jewelry—there’s no downside if you love the look.
💎 Lab-Grown Gemstones
What it means:
Lab-grown stones are created in a laboratory using advanced technology that replicates the natural conditions under which gemstones form. They are chemically, physically, and visually identical to natural stones.
Popular lab-grown stones:
Lab-grown diamonds
Moissanite
Lab-created sapphires and rubies
Why choose it:
They’re eco-friendly, conflict-free, and often more affordable. Perfect for customers who prioritize sustainability and value.
💡 At Everglow Jewelry, we specialize in custom rings with lab-grown diamonds and moissanite, ideal for ethical engagement rings without compromising beauty or brilliance.
💎 Synthetic Gemstones
What it means:
Synthetic stones are also created in a lab, but not all are identical to their natural counterparts. Some are simulants or look-alikes that imitate natural stones.
Examples:
Cubic zirconia (CZ) is a synthetic substitute for diamonds
Synthetic corundum (lab-made sapphire and ruby)
Why choose it:
They're very affordable and often used in fashion jewelry or statement pieces.
💎 Imitation Gemstones
What it means:
These are materials (often glass or plastic) made to look like real gemstones, but they do not share any of the same chemical or physical properties.
Examples:
Colored glass to imitate emeralds or garnets
Foiled-back crystals
Why choose it:
They’re budget-friendly and great for trendy pieces or casual wear, but they lack durability and long-term value.
