Let's Talk Gems!

Hi there and welcome to my Labé! I'm Olena, a gemologist with a deep love for the science and beauty of gemstones. Based in Bratislava, Slovakia, I combine academic training in mineralogy with hands-on expertise to help you make confident decisions about precious stones. Learn more about me.


Whether you're a collector searching for the perfect piece, a jeweler wanting to verify authenticity, or simply curious about a family heirloom, I'm here to help with:

Consulting

Need guidance on buying, selling, or advertising gemstones? I offer personalized advice on stone selection, quality assessment, and investment potential, whether you're a first-time buyer or a seasoned collector.

Examination

Get a clear picture of what you have. I provide detailed analysis of your gemstone's identity, quality, and any treatments, backed by a formal certificate you can use for insurance, resale, or peace of mind. See current pricing and service tiers.

I use advanced analytical techniques to ensure accurate identification:

Analytical Methods

In addition to classical gemological equipment such as a microscope, polariscope, and refractometer, my toolkit includes advanced analytical instruments: Raman spectroscopy, Fourier Transform Infrared (FTIR) spectroscopy, X-ray Fluorescence (XRF) spectroscopy, and UV-Vis-NIR spectroscopy, enabling comprehensive gemstone analysis.

Beyond lab work, I write about gemology for academic journals and the International Gem Society. I invite you to visit my blog, where I share my thoughts and insights on the latest news and trends in gemology!

Have a gemstone you'd like examined, or questions about buying one? Let's talk.
