5 Things to Know Before Choosing a Diamond or Gemstone

Selecting a center stone is both technical and emotional. Here’s how Lauren and Terry O’Sullivan help clients make informed, confident choices.

  1. Prioritize Cut. A perfectly proportioned cut releases light and life. We demonstrate how facet patterns influence sparkle so you can see brilliance, not just read numbers.

  2. Understand Color and Clarity. We teach you how tone and saturation affect appearance. Sometimes a slightly warmer diamond or an eye-clean stone offers better value without sacrificing beauty.

  3. Shape Defines Style. Each shape—round, oval, emerald, pear—carries a mood. We show you examples on hand to gauge proportion and comfort.

  4. Ethical Sourcing Matters. Lauren O Jewels works exclusively with suppliers who meet strict provenance standards. Every stone’s path—from mine to studio—is transparent.

  5. Consider Gemstone Alternatives. Natural sapphires, spinels, and emeralds add individuality. Discover options through our Custom Sapphire Sourcing service.

By pairing education with personal taste, we transform buying into learning. See our Custom Engagement Rings page to explore how stone selection integrates seamlessly with design.
