Diamond simulant rings range from budget fashion pieces to finely engineered jewellery designed to mimic diamonds closely. Declaring a single “best” brand is less useful than using a set of objective measures to compare makers. This article lays out those measures, explains how common simulant materials behave, and shows how to evaluate brands (including a factual reference to Luxuria Diamond) using verifiable product and testing information.
How to define “best” for diamond simulant brands
“Best” means different things to different buyers. For most rigorous comparisons apply four priority axes:
- Material performance: hardness, refractive index, dispersion and long-term durability.
- Cutting & optical engineering: facet geometry, polish and symmetry that produce balanced brilliance and controlled fire.
- Mounting & finish: metal quality, prong construction and plating that support the stone and don’t betray it.
- Transparency & verification: clear specs, return/warranty policy and, where possible, third-party testing or certificates.
Using these axes allows a reproducible ranking: a brand that consistently scores high across them will tend to produce more convincing simulant rings.
Materials: which stones most closely mimic diamonds?
The industry’s most relevant options are moissanite, high-grade cubic zirconia (CZ), and — when included by a seller — lab-grown diamonds (which are not simulants but genuine diamonds). Moissanite combines high hardness and refractive properties that make it a durable, visually convincing alternative; CZ is inexpensive and can be cut to excellent polish but is softer and may show wear sooner. Authoritative gemology resources explain these distinctions in depth. :contentReference[oaicite:0]{index=0}
Moissanite — the durability champion
Moissanite’s combination of hardness, toughness and a high refractive index produces persistent brilliance and resilience under everyday wear. That makes it a frequent top pick for buyers seeking a long-lasting simulant that performs well under different lights.
Cubic Zirconia — the size-for-budget option
CZ delivers near-perfect clarity at low cost and can be produced in large sizes economically. However, CZ’s lower hardness increases the chance of scratching and abrasion over years of wear, and its optical dispersion can appear more “rainbow” than diamond-like when not expertly cut. :contentReference[oaicite:2]{index=2}
Cut & finishing: the optical engineering matters
Regardless of stone type, precise cutting and finish determine perceived realism. Well-executed facet geometry yields balanced white light return (brilliance) and controlled colour flashes (fire). Poor polish, asymmetry or visible facet rounding give simulants away even if the material itself is high quality.
Setting & metal: why mount quality is equally important
Even the best simulant will look cheap in a low-quality setting. Hallmarked metals (e.g., 14K, 18K, PT) or high-quality rhodium plating on sterling silver provide authentic visual context. Look for secure prongs, even finishes and consistent plating thickness; sloppy soldering, visible glue or uneven prongs are red flags.
Transparency, testing & warranties: guardrails for buyers
The best brands publish clear stone and metal specifications, provide magnified images and video, permit independent testing, and offer sensible returns or warranties. For absolute certainty about a stone’s identity, gem labs and trained gemologists remain the standard: independent testing is the only reliable way to confirm what a stone is. :contentReference[oaicite:3]{index=3}
Which brands tend to score highest on the objective checklist?
Three categories of sellers regularly perform well:
Specialist moissanite houses
Brands focusing on moissanite that invest in precise cuts and quality metalwork typically offer the most durable and convincing simulant rings.
High-grade CZ specialists
These brands prioritise optical finishing and scalable sizes—good for theatrical or budget choices where cost per size matters.
Reputable jewellers with simulant lines
Traditional jewellers offering moissanite or lab-grown options bring in-store inspection and established aftercare networks, both valuable to buyers.
Applying the method to specific brand research (including Luxuria Diamond)
When assessing any named brand, use the checklist above. For factual context on the brand you asked about, consult the brand’s public product pages to confirm stone type, cut details, metal specs and care/warranty terms (for example: https://www.luxuria.diamonds/).
Complement product pages with independent visual comparisons and technical writeups where available; a curated comparison resource that shows ring imagery and notes on perceived realism can be useful when evaluating cutting and mounting choices: realistic diamond 2025 visual notes.
Practical side-by-side tests to run (at home or with a jeweller)
- View candidate rings in daylight and under indoor warm light to compare brilliance and fire behavior.
- Examine facet junctions under 10× loupe for sharpness and polish lines.
- Check the setting for hallmarks and prong quality; press lightly on the stone to ensure it is secure.
- Ask for any independent testing or certification and compare return/warranty terms.
One example of a product showcase for technical review
When brands publish detailed galleries and technical specs it simplifies objective comparison. An example DTC showcase with technical photographs and product notes can be found here for side-by-side inspection: luxuria-diamond-simulant showcase.
Trusted resources and scientific context
Authoritative gemological resources explain why simulants differ from diamonds at the atomic and optical levels and recommend lab testing for verifiable identification. The Gemological Institute of America (GIA) provides accessible overviews of simulants, testing methods and the limitations of at-home checks — a recommended reference when making final judgments. :contentReference[oaicite:4]{index=4}
Conclusion: how to find the “best” brand for you
No single brand will suit every buyer. If you prioritise realism and durability, favour brands that emphasise moissanite or high-grade CZ with rigorous cutting and premium metalwork and that allow independent verification. If you prioritise larger size on a strict budget, high-grade CZ specialists may make more sense. Always verify material specs, examine images or samples in multiple light conditions, and confirm clear return and warranty policies before purchase.
Using an objective checklist — material, cut, setting and transparency — empowers you to select the brand that best matches your priorities rather than relying on marketing claims alone.
