There are a lot of moissanite sellers. The market has grown dramatically over the past decade, and with that growth has come a wide range of quality, transparency, and accountability. Some sellers are exceptional. Others are not. For a buyer making a significant purchase — an engagement ring, a piece of fine jewelry intended to last a lifetime — the difference matters enormously.
This page exists because you deserve to know exactly who you're buying from, exactly what you're buying, and exactly what happens after the purchase. Transparency is not a marketing strategy for Moissanite Shine. It is the foundation of every relationship we build with every customer who chooses us.

How We Source Our Moissanite
Every moissanite stone sold by Moissanite Shine is lab-grown silicon carbide (SiC), produced in controlled laboratory environments. We source exclusively from manufacturers who meet our specifications for crystal quality, optical performance, and production consistency.
| Sourcing Question | Moissanite Shine Answer |
|---|---|
| Is it lab-grown? | Yes — all fine jewelry moissanite in existence is lab-grown. Natural moissanite (found only in meteorites and rare geological formations) is unavailable in gem-quality quantities. Lab-grown is the only standard for the industry — the question is how well it's grown and to what grade standard it's certified |
| What production method? | Chemical Vapor Deposition (CVD) and High-Pressure High-Temperature (HPHT) — the two industry-standard methods for producing gem-quality silicon carbide crystals with controlled optical properties |
| What is the minimum grade accepted? | D-color · VVS1 · Excellent cut — this is the floor, not the average. Stones that don't meet this standard are not purchased regardless of price |
| Is the standard flexible? | No — it is a fixed standard. We do not offer lower-grade stones at lower price points. Every Moissanite Shine stone online USA meets the same DEF VVS1 Excellent specification |
| Is it conflict-free? | Yes — 100%. Lab-grown moissanite requires no mining, no environmental extraction, and no supply chain with conflict exposure |
Our Grading Standard: DEF · VVS1 · Excellent Cut — Explained
D-Color: Completely Colorless
| Color Grade | Description | Visible to Naked Eye? | Moissanite Shine Standard |
|---|---|---|---|
| D (Colorless) ✅ | No detectable color under any standardized grading condition — pure white light in any setting or lighting | No — completely colorless ✅ | Our standard |
| E–F (Colorless) | Essentially colorless — microscopic warmth detectable only by trained grader under magnification | No in most conditions | Acceptable but below our D-only standard |
| G–H (Near-Colorless) | Slight warmth visible to trained eye under neutral lighting and magnification | Sometimes — warm vs. white-gold setting reveals the tint | Not accepted ❌ |
| I–J (Near-Colorless) | Faint warmth visible to trained eye face-up in neutral light | Yes in some lighting ❌ | Not accepted ❌ |
| K–Z (Faint to Noticeable) | Yellow or brown tint visible to naked eye face-up | Yes — clearly visible ❌ | Not accepted ❌ |
Color grade is the most visible quality variable in a gemstone — the one that most directly affects daily appearance. A lower color grade introduces a tint visible to the naked eye in certain lighting. We sell only D-color because we are not willing to sell stones that perform below the highest standard.
VVS1: The Clarity Standard
| Clarity Grade | Description | Visible Under 10× Loupe? | Visible to Naked Eye? | Moissanite Shine Standard |
|---|---|---|---|---|
| FL / IF (Flawless / Internally Flawless) | No inclusions under 10× magnification | No | No | Occasionally — when available at our sourcing standard |
| VVS1 ✅ | Inclusions extremely difficult to detect under 10× magnification | Extremely difficult — requires experienced grader | No — completely eye-clean ✅ | Our standard |
| VVS2 | Inclusions very difficult to detect under 10× | Very difficult | No | Not accepted ❌ |
| VS1 / VS2 | Inclusions difficult to moderately difficult to detect under 10× | Yes — trained grader can find them | Rarely — may show in certain lighting | Not accepted ❌ |
| SI1 / SI2 | Inclusions easy to find under 10× | Yes | Often — visible to careful naked-eye inspection ❌ | Not accepted ❌ |
Excellent Cut: Maximum Optical Performance
| Cut Grade | Light Performance | Moissanite Shine Standard |
|---|---|---|
| Excellent ✅ | Maximum light return — precise facet angles and proportions that return every photon entering the stone as brilliance or fire; the stone performs at its full optical capacity | Our standard — only grade we sell |
| Very Good | Most light returned — slightly less optimal facet angles; visually very close to Excellent in most conditions | Not accepted ❌ |
| Good | Some light leaks through pavilion — visible as dark areas in the stone | Not accepted ❌ |
| Fair / Poor | Significant light loss — stone looks noticeably dull compared to its optical potential | Not accepted ❌ |
GRA Certification: Independent Verification of Every Stone
| GRA Certificate Element | What It Documents | Why It Matters to You |
|---|---|---|
| Stone identity | Confirms the stone is moissanite (silicon carbide) — not CZ, glass, or synthetic corundum | Proof of what you bought — independent confirmation the stone is what was described |
| Color grade | Documents the color grade under standardized grading conditions — D, E, F, etc. | Verifiable proof that the stone is genuinely D-color — not a seller's claim |
| Clarity grade | Documents inclusion characteristics under 10× magnification — VVS1, VS1, etc. | Verifiable proof of clarity — independent of what we say about the stone |
| Cut grade | Documents facet proportions, symmetry, and polish — Excellent, Very Good, etc. | Verifiable proof the stone is cut to Excellent standard |
| Measurements | Precise millimeter dimensions of the stone | Stone identification — confirms the certified stone is the stone you received |
| Certificate number | Unique identifier registered with GRA laboratory database | Verifiable against GRA records — confirms certificate authenticity |
The GRA certificate is your protection as a buyer. It is issued by an independent laboratory whose reputation depends on grading accuracy — not by us. It is the document you'll use for insurance, appraisal, future resale, or upgrade. Every Moissanite Shine stone online USA ships with a GRA certificate included.
Our Quality Control Process
| QC Stage | What Is Checked | How |
|---|---|---|
| 1. Grade verification | Stone color, clarity, and cut grades confirmed against GRA certificate specifications | Visual inspection by trained staff under standardized lighting conditions |
| 2. Measurement verification | Stone dimensions measured and confirmed against certificate stated measurements | Precision calipers — confirms the certified stone is the stone being set |
| 3. Setting inspection (post-set) | Stone security in prongs; prong formation; metal finish quality; no metal contamination of stone surface | Visual and tactile inspection under magnification |
| 4. Final pre-ship inspection | Complete piece — stone, setting, metal finish — confirmed in perfect condition before packaging | Full inspection under magnification by accountable human inspector |
This process is not automated. Every piece is inspected by a person accountable for what leaves our facility. We believe the care taken in this process is reflected in the quality of what you receive.
The Programs That Back Every Purchase
| Program | What It Covers | Time Limit | Details |
|---|---|---|---|
| Lifetime Gemstone Warranty | Any defect in the moissanite stone itself — if a stone develops a covered defect, it is replaced | None — lifetime ✅ | Reflects our confidence that a DEF VVS1 Excellent cut stone, properly set and cared for, will not develop defects. The warranty matches the stone's permanence |
| Lifetime Upgrade Program | Apply the value of your current Moissanite Shine purchase toward a larger stone, more elaborate setting, or solid gold/platinum upgrade | None — lifetime; no minimum purchase ✅ | Designed for the reality that circumstances change. Your $500 starting ring always counts toward the ring you want in 5 or 10 years |
| Custom Design Service | Bespoke jewelry design — your stone shape, carat weight, metal type, and setting style built to your exact specification | Available at any time ✅ | Available in solid 9K, 14K, and 18K gold (all tones) and platinum; we work through the design process with you until the piece reflects your vision exactly |
How Moissanite Shine Compares: The Honest Evaluation Framework
| What to Ask Any Moissanite Seller | Moissanite Shine Answer | Red Flag from Other Sellers |
|---|---|---|
| What color grade are your stones? | D-color (colorless) — every stone, every piece ✅ | "DEF" without specifying which — often G or H-color stones sold as "near-colorless" |
| What clarity grade? | VVS1 — every stone ✅ | VS1, VS2, or unspecified — inclusions may be visible to naked eye |
| Is there an independent certificate? | GRA certificate with every stone — included in purchase ✅ | No certificate, or only a "brand" certificate issued by the seller (not independent) |
| Is there a warranty? | Lifetime Gemstone Warranty — no time limit ✅ | 30-day or 1-year warranty; or warranty only on setting, not stone |
| Can I upgrade later? | Lifetime Upgrade Program — no time limit, no minimum ✅ | No upgrade program; purchase is final |
| Is the stone conflict-free? | 100% — lab-grown, no mining ✅ | Vague or unverifiable conflict-free claims |
Why We Chose Moissanite
We didn't choose moissanite because it's a cheaper alternative to diamond. We chose it because it is, by measurable optical standards, one of the most extraordinary gemstones available for fine jewelry — and because we believe that extraordinary jewelry should be accessible to anyone who loves it, not only to those who can afford diamond prices.
Dispersion 0.104 (2.4× diamond). Refractive index 2.65–2.69. Mohs hardness 9.25. Fracture toughness 7.6 MPa·m¹⁄². Chemically inert to all daily materials. Optically permanent. These are not marketing claims — they are the measured physical properties of silicon carbide. They are the reason we chose this gemstone, and the reason we believe it deserves to be held to the same grading and certification standards as any fine gemstone.
