Frequently
Asked Questions
Our stones are crafted from premium Moissanite — a lab-created gemstone celebrated for its exceptional brilliance, clarity, and durability.
Designed to closely resemble the luxurious look of natural diamonds, Moissanite delivers stunning sparkle at an affordable price, without the environmental concerns & unethical practices often associated with mined stones.
Because Moissanite is ethically created in controlled environments, it offers a more responsible and sustainable alternative without compromising on beauty or quality.
Each stone is carefully selected to ensure a radiant finish made to shine for years to come.
We are committed to ethical sourcing and thoughtful craftsmanship, so you can wear your jewelry with confidence — knowing it was created with care, integrity, and respect by the people who made it.
Moissanite and diamonds are both high-quality gemstones, but they differ in several key ways.
- 1. Moissanite displays more rainbow-like sparkle than a diamond.
- 2. It ranks just below diamond in hardness at 9.25 on the Mohs scale (compared to diamond's 10).
- 3. To the naked eye, both stones appear very similar and are often indistinguishable without close inspection.
- 4. Moissanite provides excellent value, typically costing significantly less than a diamond of similar appearance.
Because of this, it has become a popular choice for those who want beauty, durability, and smart affordability in one stone.
No, our jewelry is designed with quality materials to prevent that from happening.
The "green finger" effect typically comes from low-quality metals reacting with moisture or skin chemistry. Our pieces are made with 925 sterling silver and finished with a protective layer of Rhodium plating , which helps create a barrier between the metal and your skin.
This means our jewelry is skin-friendly, tarnish-resistant, and crafted to maintain its finish with proper care.
Each piece from Promise Stone Jewels is handcrafted with care, a process that takes approximately 1 to 3 days.
Delivery time varies depending on the product ordered. Most items arrive within 10 to 14 business days.
