Description

This specimen features numerous small crystals of very pale green grossular on colorless diopside from the classic Belvidere Mountain (“Eden Mills”) locality. The grossular crystals are sharply formed, transparent, and show zoning or phantom growth. They are quite attractive under a scope, but you will need 10-15X to view them.

Some of the grossular crystals are shown in the four close-up photos (FOV 5.6 x 3.0 mm, 6.4 x 4.0 mm, 5.4 x 4.3 mm, 4.5 x 5.8 mm resp.) The largest grossular crystal (2.2 mm) is shown in the second photo. The fourth photo shows a pyrite aggregate 2.9 mm wide on the bottom and a rounded diopside crystal of the same size at top. The grossular crystal in the center is about 1.5 mm in diameter.

The diopside crystals can be seen in the full-view photo, but they are rather corroded.

Single item shipping weight is 2.9 oz.

Outside the USA, the stated postage and packing rate applies up to a total weight of 8 oz (225 g).

Within the USA, postage now varies by destination. For total weights up to 13 oz, it ranges from $4.50 to $7.00 (including packing etc). Above 13 oz (up to 16 oz), I will use “own box” Priority Mail. The rate, including packing, varies from $8 to $10.

Seller's terms and conditions

In addition to the standard terms and conditions, please note the following. Almost all IDs are visual. While in most cases the ID is obvious, there may be cases where it is not. If you are doubtful about a particular ID, please ask for more information. Or do not bid! Similarly, if you are not sure that the specimen meets your criteria, do not bid. I have tdone the best I can with the photos. Nevertheless, if you are not happy with a specimen for any reason, I will refund the bid price – but not the shipping costs (unless the fault is clearly mine) – if the specimen is returned. This policy applies even if analysis of the specimen shows that my ID was incorrect. When in doubt, ask - or don’t bid. Note that most crystals at MSH and Varennes are micros - even if on large specimens. Please pay attention to the stated sizes. Any customs duties, fees etc. are the responsibility of the buyer.
