What is a lab-grown gemstone?

A genuine laboratory-grown gemstone is created in a controlled environment rather than mined. When it is a true counterpart of the named stone, it has essentially the same crystal structure and chemical, optical and physical properties. It is not a simulant, although its origin, growth features, rarity and value differ from a mined stone.

How they are grown

Colored laboratory-grown stones may be produced by flame fusion, flux or hydrothermal growth, depending on the material. Laboratory-grown diamonds are commonly produced by HPHT or CVD. The process is not the same for every gemstone.

A clearer comparison

Lab-grown vs. mined gemstones

Neither origin is automatically right for everyone. Compare what changes, what stays familiar and which details matter for your ring.

Consideration Laboratory-grown Mined
Origin Created in a controlled laboratory environment and clearly disclosed as not mined. Formed in the earth and recovered through mining.
Material A true laboratory-grown counterpart has essentially the same crystal structure and material properties as the named gemstone. The naturally formed version of the same gem material.
Appearance Color and clarity vary by growth method, batch and cut. It is not a simulant. Color, clarity and inclusions vary by deposit, treatment and cut.
Price and rarity Usually more accessible because production is repeatable and supply is less constrained. Price reflects natural rarity, origin, quality and market demand.
Reports Identification or grading report availability varies by stone and order. Identification, treatment and sometimes origin reports may be available.

What to expect from Orleone

A beautiful stone is only one part of the decision. Clear disclosure, the right setting and documentation matter too.

Choose an existing design or adjust the stone, shape, metal and setting through our custom process.

Clear material disclosure

Your order should identify the center stone as laboratory-grown wherever that description applies.

Documentation by order

Report availability varies by gemstone and order. Confirm included documentation before purchasing.

Care matched to the gem

We recommend wear and cleaning guidance based on the gemstone and setting, not one rule for every ring.

Before you choose

Lab-Grown Gemstone FAQ

Straight answers about origin, durability, reports, insurance and care.

Are lab-grown gemstones real or imitation?

A true laboratory-grown counterpart is genuine gem material with essentially the same crystal structure and material properties as the named mined gemstone. It is created in a laboratory, not mined, and it is not an imitation or simulant.

How are lab-grown gemstones made?

The method depends on the gemstone. Colored stones may be produced by flame fusion, flux or hydrothermal growth. Laboratory-grown diamonds are commonly produced by HPHT or CVD. Each method creates crystal growth under controlled conditions, but there is no single process used for every lab-grown gemstone.

What is the difference between lab-grown and mined gemstones?

The primary difference is origin: one grows in a controlled laboratory and the other forms in the earth. A true laboratory-grown counterpart has essentially the same material properties, while growth features, inclusions, rarity, supply and market value can differ.

Are lab-grown gemstones suitable for everyday engagement rings?

Suitability depends on the gem and setting, not whether it was mined or laboratory-grown. Diamond ranks 10 on the Mohs scale, ruby and sapphire 9, alexandrite 8.5, and emerald about 7.5-8. Emerald generally benefits from more mindful wear and a protective setting.

Do lab-grown gemstones include a report or certificate?

Report availability varies by gemstone and order. Some laboratory-grown diamonds may include third-party grading documentation, while colored stones may receive identification reports. Contact Orleone before purchase to confirm exactly what documentation is included with your selected ring.

Can I insure a lab-grown gemstone ring?

Many insurers cover laboratory-grown gemstone jewelry, but acceptance and valuation rules vary. Keep your invoice and any supplied report, and confirm coverage directly with your insurer or specialist jewelry insurer.

How should I care for a lab-grown gemstone ring?

Use care suited to the gemstone and setting. Warm water, mild soap and a soft brush are a sensible starting point for many rings. Avoid harsh chemicals and hard impacts. Emeralds and fracture-filled stones should not automatically be placed in ultrasonic or steam cleaners.
