Authentication Standards

At Abbott & Oaks, authenticity is not assumed — it is proven. Every piece undergoes a rigorous, multi-step evaluation based on GIA (Gemological Institute of America) standards. Our process combines traditional expertise with advanced gemological tools to ensure you receive a piece you can trust.

1. Precious Metal Verification We test all gold and platinum materials through a two-step method:

  • Acid Testing: A proven field test to verify karat purity.
  • Electronic & Advanced Testing: For select pieces, we use precision tools to confirm metal content.
  • Hallmark & Construction Review: We closely inspect stamps, soldering methods, and fabrication details consistent with period craftsmanship.

2. Gemstone Evaluation Each gemstone is carefully examined to verify identity, quality, and authenticity:

  • Microscopic Inspection: We use gemological microscopes to evaluate inclusions, growth structures, and treatments.
  • Refractometer Testing: Refractive index readings help confirm gemstone species.
  • Chelsea Filter Analysis: To detect treatments and synthetics, especially in rubies, emeralds, and sapphires.
  • UV Fluorescence Testing: Ultraviolet light reveals diagnostic fluorescence patterns unique to certain gemstones.

3. Structural & Craftsmanship Assessment Authenticity goes beyond materials:

  • Hand-Crafted vs. Machine-Made Analysis: We study fabrication techniques, hallmark styles, and design motifs to ensure consistency with the claimed period.
  • Wear Patterns: Genuine vintage pieces exhibit characteristic wear that modern replicas cannot easily replicate.

4. Advanced Testing Methods For select cases where further confirmation is needed, we employ:

  • Specific Gravity Testing: To differentiate natural from synthetic stones.
  • External Laboratory Verification: For high-value items, we may submit pieces to trusted third-party labs for XRF (X-ray fluorescence) or other advanced analysis.

5. Continuous Standards We continuously refine our standards to keep pace with advancements in gemology and metallurgy. Our mission is to preserve the integrity of every piece we offer.

Authenticity is our promise — and our practice.

Ring Size Guide

Measure My Own Ring

Image of ring with arrows pointing out the diameter

  1. Choose a ring that fits your finger well.

  2. Measure the internal diameter of the ring in millimeters (mm).

  3. Use the chart to find the closest matching ring size.

Wide rings measure differently due to their fit. If you’re measuring for a wide ring, subtract 0.25–0.50 ring sizes from the measured size for a comfortable fit.

I wasn't going to, I didn’t need it but then I remembered I had been looking for an opal ring for a long time and this was the most unique setting I had ever seen. It is 100% the perfect one for my hand to make a statement. The white opal is subtle but oh the setting... and when you catch the light just right the opal reveals itself in all its introverted glory. Just like me.

I loved it even more in person. Obsessed is an understatement. I love how I continue finding unique pieces in Abbott and Oaks. I can’t wait to add more to my collection.

Customer photo review of Vintage Yuri Ichihashi Platinum Glittering Twisting 1.6mm Box Chain 16.25"

I was searching for a substantial platinum chain to use with a heavy platinum and diamond pendant. This vintage Yuri Ichihashi chain was perfect both in terms of weight and style to complement the pendant without overpowering it. I love how the twisted design of the chain catches the light and matches the sparkle of the diamonds in the pendant! This gorgeous chain really elevated the entire look of the piece!

Customer video review of Vintage 14k Yellow & White Gold Old Mine Cut Diamond Curved Enhancer Ring 6.25

I was thrilled to find this enhancer/ring guard made with old mine cut diamonds! I have a beautiful opal and diamond ring that due to of the design and weight of it tends to spin on my finger after I get it over my knuckle. This gorgeous ring guard/enhancer was the perfect solution! It frames the opal ring beautifully and holds it securely in place. I love the unique look of antique cut diamonds so this ring could not have been more perfect!

Customer photo review of Antique 14k Yellow Gold 1.18ct Lime Chrysoberyl Ruby Flower Charm / Pendant

This spectacular antique chrysoberyl and ruby pendant is stunning in person! The lime green color of the chrysoberyl is so unusual and I adore the authentic antique cut of the stone with its open culet. The ruby accents add the perfect pop of color for contrast. I am delighted to add another unique piece from Abbott & Oaks to my collection!

Customer photo review of Vintage 14k Yellow Gold Aquamarine Blue Sapphire Diamond Openwork Ring 9.00

I had bought this ring because my grandmother who had passed years prior, she always wore an Aquamarine ring that I loved. My birthstone is Sapphire. When I saw this ring, I immediately knew I had to have it since it has both Aquamarine & Sapphire stones, I saw it as sentimental. It is so stunning in person. I am a repeat customer of Abbott & Oaks due to their wonderful customer service & unique jewelry they offer.
