Buy Loose Diamonds in Houston | GIA-Certified & Lab-Grown Options

Work With Houston Gemologists

Lifetime Diamond Trade-In Promise

Every diamond or diamond jewelry purchase from Houston Jewelry—including lab-grown stones—qualifies for 100% of the original purchase price when you trade toward an item priced at least twice as much.

• Entire piece covered: We apply the credit to the full piece, not just the center stone, so halos and multi-stone designs retain their complete value.
• Confidence backed by inventory: We extend this promise because we personally select and stand behind every diamond we sell.
• Long-term flexibility: Enjoy the jewelry for years, then upgrade whenever you are ready without sacrificing what you already invested.

Few luxury items let you enjoy them for decades and still recoup every dollar toward something new.

Try asking for that kind of value retention on a designer suit or dining table—it simply does not happen.

Diamond Anatomy & Allure

Owning a diamond connects you to centuries of romance, intrigue, and craftsmanship. What was once reserved for royalty is now available in every size, shape, and color thanks to new discoveries across Africa and beyond.

Clients choose diamonds for many reasons—a proposal, an heirloom, or an investment. No matter the motivation, a few universal traits make these stones irresistible:

• Beauty: Diamonds deliver an unmistakable sparkle that instantly communicates love and success.
• Durability: As the hardest natural material, a diamond resists everyday wear so it can be passed down for generations.
• Rarity: Only about 20% of mined rough qualifies as gem quality, and extracting one carat requires processing roughly 250 tons of ore.
• Value: Prices may fluctuate with the economy, but diamonds remain one of the most concentrated, portable stores of wealth in history.

Storage & Care Checklist

Diamonds naturally pick up lotions, soaps, and everyday dust, which dulls their brilliance and can discolor precious metal mountings. A quick cleaning routine keeps them camera-ready.

Cleaning at Home

• Wipe pieces with a jeweler’s polishing cloth after each wear.
• For a deeper clean, dip the jewelry in commercial cleaner, mild detergent, or a diluted ammonia solution, then brush gently between the prongs with a soft brush.
• Rinse in clear water and dry with a lint-free cloth. Ultrasonic cleaners are also safe for most diamonds and create high-frequency turbulence for a fast refresh.

Do / Don’t Reminders

• Do: Store diamonds separately in fabric-lined boxes or divided cases, and schedule an annual prong check with Houston Jewelry for a professional polish.
• Don’t: Toss pieces together in a drawer—diamonds can scratch other gemstones and each other.
• Don’t: Wear your diamond engagement ring during heavy labor where a hard blow could chip it.
• Don’t: Expose mountings to chlorine bleach; it can pit and discolor the metal.

Diamond Grading Disclosure

The unique beauty of a diamond can only be appreciated in person. Laboratory grading is an expert opinion based on proprietary standards, and two respected labs can reach different conclusions on the very same stone.

For that reason, we encourage every client to review diamonds with a gemological microscope (10x dark-field illumination) and treat certificates as reference tools, not absolute guarantees.

• Grades can vary between laboratories and even between submissions to the same lab.
• Houston Jewelry’s use of a laboratory report does not equal endorsement of its grading results.
• Purchasing without visual inspection often leads to disappointment because stones with identical specs can look dramatically different side-by-side.

Limitation of Liability

A Diamond Laboratory Grading Report (“Report”) is an independent third-party opinion. Houston Jewelry makes no representations or warranties, express or implied, regarding such Reports, their accuracy, or how one laboratory’s proprietary system compares with another’s.

Houston Jewelry Inc. is not liable for any loss, damage, or expense—including consequential, incidental, indirect, exemplary, statutory, special, or punitive damages—arising from errors, omissions, issuance of, use of, or reliance upon any Report, regardless of notice.
