Moissanite vs Lab Grown Diamonds: Honest Comparison
Moissanite and lab-grown diamonds both offer affordability and brilliance. But they are not the same. Compare appearance, durability, value and cost.
What Are They?
Lab-grown diamonds are physically, chemically and optically identical to mined diamonds — they are real diamonds, grown in a controlled environment. Moissanite is a separate gemstone (silicon carbide) that resembles diamond but has different optical properties. At TONGLIN, we offer both options so you can choose what fits your budget and values.

| Brilliance | Fire + white sparkle | More rainbow fire |
| Price (1ct) | ~$800-$1,500 | ~$200-$400 |
| Resale value | Minimal but real diamond value | Very low |
| Certification | IGI / GIA | No diamond grading |
Which Should You Choose?
Choose lab-grown diamond if you want a real diamond with certification and maximum durability. Choose moissanite if budget is tight and you prioritize maximum sparkle per dollar. Both are ethically sourced. Ask us which fits your design.

Can you tell moissanite from a diamond?
To the naked eye, moissanite often shows more rainbow fire. A jeweler with a refractometer or tester can identify it instantly.
Is moissanite fake?
No. Moissanite is a real, distinct gemstone. It is not diamond simulant like cubic zirconia, but it is not diamond either.
Does moissanite cloud over time?
High-quality moissanite does not cloud. Cheaper lower-grade stones may show internal cloudiness over decades.
