• 21.26 ct Large emerald cut Bolivian Amethyst. A natural purple eye-clean gem

    An extremely large, emerald cut Amethyst. A very well finished gem, with a superb polish that looks like it's come straight off the lapidary wheel. Colour saturation is a moderate purple, but slightly zoned in places. This is a stunning gem that anyone would be proud to own / work with. All my gems and minerals come with a small free gift. The gift is intended as a little fun to go with your purchase: most are relatively cheap gemstones but there are also a few lucky ones which aren't! To make it interesting for those who want a challenge, the gem is only identified inside the slip of paper. I hope you enjoy the challenge as much as I always do..

  • 13.32 ct Large Bolivian Amethyst. Eye clean with stunning polish and cut.

    A large, oval cut Amethyst. I can't say enough good things about this gem. Colour is a stunning purple and the cut is as good as it gets without being a custom job. When you see the polish and all round general finish of this gem, it makes you realize the difference between a run of the mill gemstone and a collector's piece.

  • 21.31 ct Big Bolivian Amethyst with a quality oval cut. A natural purple gem.

    A very large, oval cut Amethyst. A 100% natural gemstone with no treatments and a deep purple colour. There is some minor colour zoning when viewed through the bottom of the gem but this isn't visible through the top. The first thing you notice about the gem is just how many facets have been worked into the cut, quickly followed by amazement at just how many of the facets are sparkling extremely brightly. The gem is very well finished, with an excellent polish and all round symmetry.The girdle is straight and even, as well as very little facet misalignment. Simply put: a stunning gemstone for a wholesale price.All my gems and minerals come with a small free gift.

  • 17.64ct Large Bolivian Ametrine. Purple and gold with a bright, pear cut.

    A nice, bright, large Ametrine. Size is impressive enough for either a pendant or a collection. The gemstone contains some brilliant examples of two phase inclusions - too small to be visible to the naked eye (so no worry for jewelry purposes), but they add something extra and interesting to a collector with a microscope. Colour ranges from purple through peach to gold, with the split occurring diagonally across the gemstone. Cut is a nicely proportioned pear and finished with a high degree of polish. All my gems come with a small gift. It is just a little fun to go with your purchase. To make it interesting for those who want the challenge of identifying the gem themselves, the gem id is in a closed slip..
