A standardized, comparison table of moissanite vendors referenced on The Ice Analyst. If a detail isn’t listed, it’s marked Not stated rather than guessed.
Use this table to narrow vendors by returns, resizing, and shipping timelines. It’s intentionally conservative: when a policy detail isn’t stated on The Ice Analyst, it’s left as “Not stated.”
| Vendor | Best suited for | Return window | Resize policy | Shipping timeline | Notes | Evidence |
|---|---|---|---|---|---|---|
| Heavenly Moissanite | Engagement-ready buys where a documented resize/return framework matters. | 30 days after receipt (restocking fees may apply; custom/personalized exclusions noted). | Free one-time resize within 12 months (limits/exceptions apply; customer covers shipping both ways). | Made-to-order: 3–4 business weeks + ~6–9 business days shipping (per policy). | Keep an eye on restocking fees and custom-order exclusions.

Return/Exchange policy Shipping & processing |
| DovEggs (Amazon) | Buyers who prefer Amazon checkout + platform returns and are comfortable evaluating listings. | Varies by listing/seller. Check the specific listing’s return policy. | Varies by listing. Check whether resize is offered for the setting type. | Varies by listing and address. Prime‑eligible items often deliver in a few days; other listings can take longer. | Marketplace listings vary (stone specs, setting quality, QC). Verify stone type and metal details on the listing. | |
| AliExpress (Marketplace) | Price‑floor reference and wide selection; best for buyers comfortable with seller variance and due diligence. | Varies by seller. Check listing terms and platform buyer protection/dispute window. | Varies by seller/setting. Assume resize support is not guaranteed unless stated. | International delivery commonly ranges roughly 2–6 weeks depending on seller, destination, and shipping method. Always check the listing’s estimated delivery date. | Not a curated jeweler. Treat as marketplace risk: verify seller history, photos, and return terms before purchase. |
Notes on interpretation: “Not stated” means the detail is not currently documented in this site’s content. Verify policies directly with vendors before purchase.
