We Buy Loose Diamonds of All Shapes, Sizes, and Grades
Loose diamonds are valuable—if evaluated correctly. We purchase all types of diamonds, including:
Round brilliant
Princess cut
Emerald cut
Cushion cut
Oval, pear, marquise, heart, and other fancy shapes
Certified diamonds (GIA, EGL, IGI, AGS)
Uncertified diamonds (we’ll provide expert grading in-house)
We buy diamonds 0.25 carats and larger, and specialize in stones that are:
Whether your diamond is colorless or fancy-colored (yellow, blue, pink, etc.), our gemologists will evaluate cut, clarity, color, and carat weight (the 4Cs) and provide a no-obligation offer based on current global market pricing.
We Also Buy Precious Gemstones
In addition to diamonds, we buy a wide range of precious and semi-precious stones, including:
Sapphires – blue, pink, yellow, and fancy varieties
Emeralds – Colombian, Zambian, and more
Rubies – Burmese and Mozambique rubies
Tanzanite, aquamarine, tourmaline, and spinel
Natural pearls and cultured pearls
Loose stones with lab reports or appraisals
Gemstones with rich color saturation, natural origin, and minimal treatment often command premium prices—and we know how to identify those value factors with accuracy.
Why Choose Jon Bragman, Inc. to Sell Loose Stones?
Unlike gold buyers or pawn shops that price stones strictly on size or assumptions, we provide professional-grade evaluations that consider:
Certified gemological testing
Market trends and international demand
Clarity enhancement or treatment detection
Brand or provenance (for notable diamonds)
Potential for resale or investment
We also have access to a network of private collectors and diamond dealers, enabling us to offer more competitive prices than retail trade-in or online platforms.
