Learn what makes your diamond valuable
Cut determines brilliance and sparkle. Grades: Excellent, Very Good, Good, Fair, Poor. Excellent cut diamonds command premium prices - they reflect light beautifully and appear more brilliant.
Graded D (colorless) to Z (light yellow). D-F are colorless and most valuable. G-J are near colorless and popular. Fancy colors (pink, blue, yellow) are separate and can be extremely valuable.
Measures internal inclusions and external blemishes. Scale: FL (Flawless), IF, VVS1-VVS2, VS1-VS2, SI1-SI2, I1-I3. Flawless and VVS diamonds are rare and valuable. VS and SI can offer excellent value.
1 carat = 200 milligrams. Larger diamonds are exponentially rarer and more valuable per carat. Price jumps significantly at certain weights: 0.50ct, 1.00ct, 2.00ct, 3.00ct.
GIA certified diamonds command highest prices due to strict grading standards. AGS and HRD also respected. Certification increases value 5-15% and speeds sale process. We buy diamonds with or without certificates.
Diamonds can fluoresce under UV light (None, Faint, Medium, Strong). Strong blue fluorescence can lower value in colorless diamonds but isn't always negative. We evaluate each diamond individually.
Engagement ring values depend on the diamond's 4 C's (cut, color, clarity, carat), the setting metal and quality, designer brand if applicable, and current market conditions. A 1-carat diamond engagement ring in good condition typically sells for $3,000-$8,000, but can be much higher for premium stones or designer pieces. GIA certification significantly increases value. Bring it in for a free expert appraisal - we'll explain the exact value factors.
No, certificates aren't required! While GIA, AGS, or other lab certificates increase value and speed the sale, we buy diamonds with or without paperwork. Our gemologists can grade your diamond accurately even without certificates. If you have original purchase receipts or insurance appraisals, bring those - they help establish provenance and value.
Absolutely! We love buying loose diamonds - they're often easier to evaluate and grade accurately. Loose stones from 0.25 carats to 10+ carats are all welcome. GIA certified loose diamonds command the best prices, but we buy uncertified stones too. Bring any documentation you have, and we'll provide a fair market-based offer.
We still buy damaged diamonds! Chips, cracks, or other damage does affect value, but diamonds with issues are still worth money - often thousands of dollars depending on size and quality. Minor chips can sometimes be polished out. We'll evaluate the damage honestly and make the best possible offer. Don't assume a damaged diamond is worthless - bring it in!
Our gemologists use multiple professional methods: thermal conductivity testers, examining under microscopes (real diamonds show specific internal characteristics), testing hardness (diamonds are the hardest natural material), checking refractive properties, weighing (diamonds have specific density), and UV light testing. We have decades of experience distinguishing real diamonds from simulants like cubic zirconia or moissanite.
We're direct diamond buyers with over 14 years in Manhattan's Diamond District. Our low overhead, industry connections, and efficient operation mean we can pay 10-20% more than jewelry stores, pawn shops, and online buyers. We don't work on consignment or use middlemen - you deal directly with decision-makers who can offer top dollar immediately.
Yes! We're very interested in fancy color diamonds - yellow, pink, blue, green, and other colors. Fancy color diamonds are rare and valuable, with some colors (especially vivid pink and blue) commanding premium prices. Natural fancy colors are worth far more than treated or enhanced stones. Bring your fancy color diamond with any documentation for expert evaluation.
Vintage diamond cuts are highly desirable! Old mine cuts, old European cuts, and other antique cuts have unique charm and character. While they may not have the brilliance of modern cuts, they're sought after by collectors and vintage jewelry enthusiasts. We appreciate vintage diamonds and offer fair prices reflecting their historical value and rarity.
Yes, we frequently purchase estate diamonds and heirloom pieces. For estate sales, you'll need to show proof you have legal right to sell (executor documents, will, or estate paperwork). We handle these transactions with sensitivity and respect. Estate diamonds often have sentimental value - we'll explain everything clearly so you can make an informed decision.
Professional diamond appraisals typically take 10-20 minutes per stone. For engagement rings with side stones, 15-25 minutes. If you have multiple pieces or large diamonds requiring detailed examination, allow 30-45 minutes. We never rush - accurate grading takes time. You're welcome to watch the evaluation process and ask questions throughout.
Valid government-issued photo ID is required (driver's license, passport, or state ID). This is New York law for precious metals and jewelry transactions. We keep your information confidential. This legal requirement protects buyers and sellers from fraud and stolen property. For estate sales, additional documentation may be needed.
We primarily focus on natural diamonds, which hold significantly more value. However, we'll evaluate lab-grown diamonds on a case-by-case basis, especially larger high-quality stones with certification. Lab-grown diamonds typically sell for 60-80% less than equivalent natural diamonds. Be upfront about whether your diamond is natural or lab-grown.
