Who am I?
My name is Martijn Antonius, and I have had a deep affinity with gemstones and their energetic effects for as long as I can remember. Through many years of practical experience, thorough literature study, and focused training, I have developed a clear and grounded understanding of gemstones, minerals, and crystals.
Kristalmeester was created from the desire to share this knowledge with care and integrity. Each gemstone is personally selected and described from experience, so you can rely on authenticity, quality, and trustworthy information. This way, you do not choose just any stone, but a gemstone that truly suits you.

Every stone is unique
Each gemstone has its own origin, structure, and energetic vibration. No two stones are exactly the same. When you take the time to look and feel calmly, you will often notice which stone naturally draws your attention.
The attraction is no coincidence. It may reflect something that is present within you at that moment, a need for calm, clarity, strength, or balance.
At Kristalmeester, gemstones are carefully selected and described as clearly as possible, so you choose not only by appearance, but also by feeling and meaning. In this way, each description helps you find the stone that best suits you at this moment.
My mission!
With Kristalmeester, I invite you to slow down, to look, and to feel. Gemstones reveal the beauty of what has been shaped by nature over a long period of time and remind us that growth, too, requires time, attention, and gentleness.
By consciously choosing a stone and allowing its energy into your daily life, space can arise for insight, acceptance, and inner calm. Each stone on this website is carefully selected to support you in this. My wish is that you recognize that you do not need to become who you think you should be, but may discover who you already are. From that awareness, growth can emerge that carries through into how you live, choose, and contribute to the world around you.
What do we do?
At Kristalmeester, we share our experiences and knowledge about gemstones, minerals, and crystals in an attentive and personal way. The descriptions on the Kristalmeester website are intended as inspiration and support, helping you to consciously and intuitively choose a stone that suits you.
Gemstones can be a valuable addition to daily life, but they are never a substitute for professional medical or psychological care. Therefore, the information on this website should not be considered medical advice. If you experience physical or mental complaints, it is always important to contact your physician or another qualified healthcare professional.
Quality mark
Kristalmeester is affiliated with Fair Trade Minerals & Gems (FTMG), an international non-profit organization dedicated to fair trade in minerals and gemstones. FTMG promotes transparency and respect for people, nature, and the environment, and works to improve conditions for everyone involved in the extraction and mining of gemstones.
For Kristalmeester, this means consciously considering origin, working conditions, and environmental impact. It is important that people receive a fair compensation for their work and that nature is respected and, where necessary, restored or compensated. In this way, gemstones carry not only beauty, but also care and responsibility.
