Lab-Grown Diamonds at Beverly & Brilliance

At Beverly & Brilliance, we exclusively work with premium lab-grown diamonds, offering the same brilliance, durability, and beauty as mined diamonds—without the ethical or environmental concerns.

What Are Lab-Grown Diamonds?

Our lab-grown diamonds are real diamonds, created using advanced technology that replicates natural diamond formation. They are composed of pure crystalline carbon and are atomically, chemically, and optically identical to mined diamonds.

We offer two premium lab-grown diamond types:

💎 CVD Lab-Grown Diamonds (Chemical Vapor Deposition)

• Visually indistinguishable from mined diamonds—even to trained jewelers
  
• Exceptional fire, brilliance, and clarity
  
• Ideal for fine jewelry and everyday wear
  

💎 HPHT Lab-Grown Diamonds (High Pressure High Temperature)

• Created under extreme conditions similar to the Earth’s mantle
  
• Highly durable and long-lasting
  
• Available in colorless and select fancy tones
  

Diamond Testing

✔ Yes, our lab-grown diamonds pass standard diamond testers

✔ Confirmed as real diamonds using professional gem-testing equipment

In rare cases, specialized laboratory equipment may be able to identify growth origin (lab vs. mined), but to the naked eye and in daily wear, they are identical.

Diamond Certification

• All lab-grown diamonds above 0.40 carat include an IGI Certificate
  
• Certification confirms authenticity, cut, color, clarity, and carat weight
  

Stone Comparison

• Lab-Grown Diamonds: Top-tier diamond quality
  
• Identical brilliance and durability to mined diamonds
  
• Ethical, sustainable, and conflict-free
  
• Exceptional value without compromising luxury
  

Appraisal Information

Our lab-grown diamonds may be appraised by any local jeweler.

Please note that appraisal values may vary depending on market conditions and the appraiser’s evaluation method. For this reason, we cannot guarantee a specific appraised value.

Everyday Wear & Preventive Care

At Beverly & Brilliance, our jewelry is thoughtfully crafted for daily wear, allowing you to express your timeless style with confidence. We take pride in the quality and durability of every piece; however, preventive care is essential to maintain its beauty over time.

Important Note on Plated Jewelry

We do not recommend purchasing silver with black or colored plating if you are seeking a finish that lasts forever.

While we use high-quality rhodium and colored platings, plating longevity varies by individual and depends heavily on factors such as skin chemistry, daily wear, exposure to water, chemicals, and friction. As a result, black and colored platings may fade, chip, or wear off over time, even on solid gold pieces.

Plating may last anywhere from a few days to several months or even years, but wear is considered normal and is not eligible for refunds.

For a longer-lasting finish, we strongly recommend:

• Non-plated silver
  
• Solid gold without colored plating
  

Metal Guide

Platinum

Platinum is prized for its exceptional durability, rarity, and hypoallergenic properties, making it ideal for sensitive skin. Naturally white and heavier than gold, it does not require rhodium plating and is highly resistant to tarnish. Platinum is often chosen for engagement and wedding rings due to its timeless elegance.

Platinum Markings: Pt950, Pt900

Solid Gold

Our solid gold jewelry is handcrafted for everyday wear with a permanent finish that maintains its beauty over time.

Gold Purities Available:

9K, 10K, 14K, 18K, 24K

925 Sterling Silver

Our sterling silver jewelry is electroplated with rhodium or finished with an e-coating to enhance appearance and offer added protection. However, these finishes are temporary and may wear off with regular use.

For engagement or wedding rings, we recommend silver without colored plating, as finishes such as rose gold, yellow gold, or black rhodium tend to fade faster.

Silver Markings & Labels:

• S925 – Sterling Silver
  
• 925RG – Silver with Rose Gold Plating
  
• 925YG – Silver with Yellow Gold Plating
  
• 925WG – Silver with White Gold Plating
  
• S700 – Silver with Platinum Finish
  
• 925 + White Gold – Sterling Silver with Gold Plating
  

Black-Plated Jewelry

Black plating is a temporary finish and may wear off with frequent use. Longevity depends on individual wear habits and care. We have seen black plating last anywhere from days to months or even years, but wear is normal and expected.

Tungsten Carbide

Known for its exceptional hardness and scratch resistance, tungsten carbide is a popular choice for rings. While extremely durable, no metal is completely scratch-proof. Most finishes are permanent, though coated finishes may wear over time with heavy use.

Titanium

Titanium is lightweight, durable, and hypoallergenic, making it an excellent everyday option. While scratch-resistant, certain coatings or finishes may wear over time with heavy use.

Stainless Steel

Highly resistant to corrosion and tarnish, stainless steel is a durable and budget-friendly option. Polished finishes may show scratches more easily than brushed finishes.

Brass / Copper

Brass and copper pieces are stylish but not recommended for daily wear, as their finishes are not permanent.

Importance of Preventive Care

To keep your Beverly & Brilliance jewelry looking its best, we recommend following these care guidelines:

Maintenance Tips

• Avoid exposure to harsh chemicals, household cleaners, and chlorine
  
• Remove jewelry before sports, swimming, or household chores
  
• Store pieces in a soft cloth or jewelry box to prevent scratches
  
• 
  Clean gently using mild soap, warm water, and a soft brush
  
• Schedule professional inspections to maintain long-term quality
  

For maximum longevity, we recommend choosing solid gold or non-plated silver and avoiding plated or coated finishes.

Free Black Plating Maintenance (Limited)

Black rhodium plating appears dark grey to black and is a highly intricate process. Its longevity varies based on exposure to water, soaps, skin oils, and chemicals. As a courtesy, we offer complimentary re-plating within 3 months of purchase, subject to evaluation.

Our customer support team is available Monday through Friday, 9:00 AM to 6:00 PM (EST).
