Darlene:

On my opinion the single crystal ("citrine point") shown on the photos is heat treated amethyst, for 2 reasons:

- the color shade tends to orange; heated trated amethyst can be deep orange to light orange, but showing a shade that is not found in natural crystals

- on all photos of natural citrine that were posted in reply of your original question you can see that the crystals have a long prism, showing approximately the same widh from the bottom to the top; your citrine point has a wide top and a narrow bottom, and this shape is typical from amethyst crystals detached from the original geodes, where the most developed faces are the termination faces, followed by much shorter prism faces, and then, on the direction of the bottom, the several crystals packed together interact with each other, resulting on narrower irregular contact surfaces, so that is probably why your polished point has a wider termination and a narrow bottom.

So on my opinion your specimen is a heat treated amethyst that was originally part of a large amethyst geode.
