- Miniature, 4.9 x 3.2 x 2.2 cm
- Antsongombato, Betafo Region, Madagascar
- Ex. Dr. David London
While not as large or yellow as the next londonite, listed below, this 1.5 cm across crystal, on a quartz matrix, does have the remnants of rubellite crystals for a color contrast. I actually got this from Dave London years ago and it comes with his signed card.
