Why Buy Loose Diamonds?

Buying loose diamonds gives you complete control over your engagement ring or jewelry design. Instead of selecting from pre-set designs, you can choose the exact diamond based on cut, clarity, carat, color, and shape that fits your style and budget.

Benefits of Loose Diamonds:

  1. Customization: Pair your diamond with the perfect setting to create a unique, one-of-a-kind piece.
  2. Better Value: Compare stones individually to find higher quality at a lower cost than pre-set rings.
  3. Transparency: Evaluate each diamond using the 4Cs (cut, color, clarity, carat) and certified grading reports.
  4. Investment Potential: High-quality loose diamonds maintain long-term value and can be passed down through generations.

Our experts will help you select the ideal loose diamond for your dream engagement ring or custom jewelry piece, ensuring a perfect combination of brilliance, beauty, and lasting value.

  • Cushion: Rounded corners with a pillow-like shape, combining vintage charm and sparkle.
  • Oval: Elongated and elegant, creating a larger visual appearance.
  • Emerald: Rectangular step-cut with a sophisticated, mirror-like effect.
  • Asscher: Similar to emerald but square with a vintage art-deco appeal.

How to Store Loose Diamonds?

Proper storage protects your loose diamonds from damage, loss, and scratches. Follow these tips to keep your stones safe and in perfect condition:

  1. Use Individual Containers: Store each diamond in a separate box, pouch, or compartment to prevent scratches from contact with other stones.
  2. Soft Materials: Place diamonds on soft fabric, felt, or velvet to cushion and protect them.
  3. Label Clearly: Keep certificates or grading reports with each diamond to maintain identification and provenance.
  4. Secure Location: Store diamonds in a locked jewelry safe or secure location away from moisture and extreme temperatures.
  5. Avoid Handling: Handle diamonds minimally and with clean hands to prevent oils or dirt from affecting their brilliance.

We offer guidance and trusted solutions for storing and safeguarding your loose diamonds, ensuring they remain as brilliant and valuable as the day you acquired them.

How to Clean Loose Diamonds?

Keeping your loose diamonds sparkling is simple if you follow proper care. Here’s how:

  1. Gentle Soap and Water: Soak diamonds in warm water with mild dish soap for 20 – 30 minutes.
  2. Soft Brush: Use a soft-bristled toothbrush to gently remove dirt from crevices.
  3. Rinse Thoroughly: Rinse under lukewarm running water to remove soap residue.
  4. Dry Carefully: Pat dry with a soft, lint-free cloth. Avoid tissues or paper towels that can scratch.
  5. Professional Cleaning: For heavily soiled or older stones, professional cleaning and inspection at a trusted jeweler ensures the diamond retains its brilliance.
