What Are Black Diamonds?

  • Natural Carbonado: Ultra-rare, mined in Brazil and the Central African Republic. These polycrystalline stones contain graphite inclusions, giving them an opaque, inky appearance and exceptional toughness.

  • Treated Black Diamonds: More accessible, created by heat or irradiation of lower-grade white or brown diamonds to achieve a uniform black hue.

The Appeal of Black Diamond Jewelry

  1. High-Contrast Drama: The deep black of the stones creates a vivid contrast against bright metals and colored gemstones—ideal for eye-catching necklaces, bold rings, and standout bracelets.

  2. Superior Durability: Scoring a perfect 10 on the Mohs scale, black diamonds resist scratches and everyday wear, making them perfect for long-lasting fine jewelry.

  3. Modern Versatility: From minimalist stud earrings and sleek cuff bracelets to two-tone pendants and statement rings, black diamond jewelry transitions effortlessly from casual to couture.

  4. Fashion-Forward Edge: Incorporating black diamonds into classic and avant-garde designs adds a contemporary twist to timeless silhouettes. men’s bands, and mixed-metal designs that exude modern sophistication.

Styling & Care Tips

  • Pair with Metals: Contrast black diamonds with yellow or rose gold for warmth, or choose white gold and platinum for a cool, sophisticated palette.

  • Layer & Stack: Mix black diamond pieces with colored gemstones or diamond pavé for textured, multi-dimensional looks.

  • Cleaning: Gently wipe with a soft cloth and mild soap; avoid ultrasonic cleaners on treated stones.

  • Storage: Keep each piece in its own pouch to prevent scratches.

Exceptional Craftsmanship and Service at J&M Jewelry! I am absolutely thrilled with the repair and service I received from J&M Jewelry in Houston for my diamond earrings! From start to finish, the entire experience was outstanding, demonstrating a level of professionalism and skill that is hard to find. First, the turnaround time was incredibly quick—far faster than I anticipated. More importantly, the quality of the work speaks for itself. They didn't just fix the issue; they elevated the quality of my earrings entirely. The jewelers installed new, secure ear posts which have made the earrings feel stronger and more comfortable than they ever were before. As a brilliant finishing touch, they also provided a professional cleaning. My diamonds are now sparkling with a renewed fire that genuinely makes them look brand new. The care and attention to detail J&M Jewelry provided shows that they truly value their customers and their craft. If you are looking for prompt, high-quality jewelry repair or restoration in the Houston area, I highly recommend J&M Jewelry. They went above and beyond, and I couldn't be happier with the results!
