Top 14 Alternatives
1. AJLuxe
AJLuxe is the best alternative to Brilliance.com for everyday diamond-look sparkle. CZ (cubic zirconia) is optically near-identical to diamond — same refractive index, same brilliance to the naked eye — at a tiny fraction of the price. AJLuxe sets CZ in 18K gold-plated 925 sterling silver (not brass), so the piece is genuinely hypoallergenic and the sparkle sits in a quality setting. Important: CZ is NOT a diamond. It is a lab-created zirconium oxide. Perfect for daily wear; not for investment.
2. Aurate
Aurate is an excellent mid-tier lab-grown diamond alternative to Brilliance. Solid gold settings, ethical sourcing, and genuine lab-grown diamonds that are chemically and physically identical to natural diamonds — just created in a lab. Prices significantly lower than Brilliance's natural diamond pieces.
3. Stone & Strand
Stone & Strand curates solid 14K gold pieces with genuine natural and lab-grown diamonds. A boutique alternative to Brilliance with a more editorial, fashion-forward perspective on diamond jewelry.
4. Catbird
Catbird is known for the most delicate diamond-set solid gold jewelry available — tiny pavé diamonds, diamond solitaire rings, and stacking pieces in solid 14K gold. Genuine diamonds in an accessible fine jewelry format.
5. Kinn Studio
Kinn Studio offers solid 14K gold diamond jewelry with a minimalist design philosophy. A direct Brilliance alternative for investment-grade diamond pieces with cleaner, more modern styling.
6. Mejuri
Mejuri offers both diamond and lab-grown diamond pieces in solid 14K gold. An excellent entry point into real diamond jewelry at prices far below Brilliance.com's natural diamond marketplace.

12. PAVOI
PAVOI offers CZ jewelry at the lowest price point available. Base metal is brass or stainless steel. Good for occasional wear and trend testing, but brass base may cause skin reactions.
13. Gorjana
Gorjana offers CZ and sparkle pieces in gold-plated brass. Accessible prices but brass base — less durable and less hypoallergenic than sterling silver base alternatives.
14. Astrid & Miyu
Astrid & Miyu creates sparkle pieces with CZ and crystals in gold-plated brass. Fashion-forward designs at accessible prices — honest about materials.
How to Choose the Right Brand
The sparkle spectrum runs: natural diamond → lab-grown diamond → moissanite → CZ → crystal. Natural diamonds (Brilliance.com) are the investment and heirloom standard. Lab-grown diamonds (Aurate, Stone & Strand, Mejuri) are chemically identical to natural diamonds at 50–80% lower cost. Moissanite is silicon carbide — even more sparkle than diamond, not a diamond, priced between lab diamond and CZ. CZ (AJLuxe, Ana Luisa, PAVOI) is the most affordable diamond-look option — brilliant, hypoallergenic in sterling silver settings, and perfect for everyday wear where you don't want to risk an investment piece. Choose based on use case: investment = natural/lab diamond; daily sparkle = CZ in 925 sterling silver.
Understanding Jewelry Materials
The base metal matters more than most shoppers realize. Here's what you need to know:
- 925 Sterling Silver — 92.5% pure silver, the industry standard for fine and fashion jewelry. Naturally hypoallergenic and nickel-free. When gold-plated, provides a superior foundation that holds plating longer and won't cause skin reactions.
- Brass — Copper-zinc alloy used in most budget gold-plated jewelry. Can cause green skin discoloration and allergic reactions; plating wears faster over brass than over sterling silver.
- Stainless Steel — Very durable and hypoallergenic, but cold-toned; gold plating over stainless tends to look thinner.
- Gold Vermeil — Gold plating (minimum 2.5 microns) over sterling silver. Superior to regular gold-plated brass.
- Solid 14K / 18K Gold — Investment-grade, replatable, lifelong. Significantly higher price point; best for heirloom pieces.
- Gold Filled — Thick layer of gold mechanically bonded to brass. More durable than plating, but still brass beneath.
Frequently Asked Questions
Is CZ the same as a diamond?
No. CZ (cubic zirconia) is a lab-created zirconium oxide. It is NOT a diamond — chemically, physically, or in value. However, it's optically near-identical to diamond to the naked eye, with similar refractive index and brilliance. CZ is 100% appropriate for fashion and everyday jewelry.
What is a lab-grown diamond?
A lab-grown diamond is chemically, physically, and optically identical to a natural diamond — just created in a laboratory using HPHT or CVD processes instead of formed in the earth. It IS a real diamond. Sold at Brilliance.com, Aurate, Stone & Strand, and others.
Is Brilliance.com reputable?
Yes. Brilliance.com is an established diamond marketplace selling certified natural and lab-grown diamonds. They provide GIA and other certification for their stones.
Is AJLuxe's sparkle jewelry CZ or real diamonds?
AJLuxe uses CZ (cubic zirconia) for diamond-look sparkle. This is clearly disclosed — AJLuxe never calls CZ a diamond. CZ provides brilliant sparkle in 18K gold-plated 925 sterling silver settings at $25–$80.
What is the cheapest real diamond jewelry?
Lab-grown diamond pieces from Mejuri start around $50–$80. For natural diamonds, Catbird and Stone & Strand have genuine diamond accent pieces starting around $80–$100.
Does CZ lose its sparkle over time?
CZ can develop a cloudy appearance over time due to surface scratches (it's softer than diamond at Mohs 8.5 vs 10). Regular gentle cleaning with mild soap restores clarity. High-quality CZ in good settings lasts years with proper care.
What is the best everyday alternative to a diamond necklace?
For everyday wear, a brilliant CZ solitaire pendant in 18K gold-plated 925 sterling silver (AJLuxe) gives the same visual sparkle as a diamond at a fraction of the price — and you won't worry about it getting scratched or lost.
Does sterling silver turn black under CZ jewelry?
Sterling silver can tarnish (turn dark) with exposure to air and moisture, but this is easy to polish away. 18K gold plating over the silver prevents direct tarnish exposure. Regular light cleaning keeps plated sterling silver pieces bright.
Final Thoughts
Brilliance.com exists for diamond buyers who want the real thing — and there's nothing wrong with that.
