大 き さ 標本部分の大きさ105 x 63 x 22mm(スタンドを含む合計136.35g)
産   地 Rio Colorado, Mendoza, Argentina

ハーフカットノジュール、断面平面研磨品(グルーでスタンドが固定されています)。
リオコロラド・サンダーエッグの名で流通。

アルゼンチンのコロラド川沿いで発見されたサンダーエッグで、2006年頃から市場で見かけるようになりました。
この産地のサンダーエッグは、歪な形状の赤茶色の母岩の割れ目に、赤や黄色〜茶色の細い瑪瑙の層が見られるのが特徴です。
アメリカのオレゴンのサンダーエッグとは異なる、コンドルアゲートと似た感じの色合いです。
原石と未研磨のカットノジュールも当店に少し在庫がございますので、ご入用の方はお知らせください。

Ex. Ed Pieters.


サンダーエッグとは
サンダーエッグは、主に流紋岩(稀に玄武岩やその他の火成岩)で、ジオードに似たノジュール状の岩です。
デコボコした球体で、ほとんどが野球ボールほどの大きさですが、直径が1cmから1mを超えることもあります。
それらは、アゲート(カルセドニー)、ジャスパーまたはオパールを含んでいます。これらに加え水晶を伴うこともあります。
外見は普通の岩のように見えますが、半分にカットして研磨すると、複雑な模様や色が現れることがあります。
サンダーエッグはジオードと同義ではありません。
ジオードは、多くの場合、成長し形成した結晶を伴う、中空の岩石の簡単な用語です。
一方、サンダーエッグは特定の地質構造で、アゲートの形態の一つです。

サンダーエッグの名の由来について(諸説あり)
アメリカ先住民ワスコ族の伝説によると、この岩はフッド山とジェファーソン山にすんでいたサンダーバード(特定の北米先住民族の歴史と文化において伝説的な生き物)の卵であると考えられています。
2つの山の雷の精霊は、お互いにその卵を投げつけました。
喧嘩が始まるとともに激しい雷雨が生じたといいます。
そして、猛烈な怒りの中で投げられた沢山の卵は、オレゴン中央部の高原に散らばりました。
(1965年3月30日、サンダーエッグはオレゴン州議会の共同決議によってオレゴン州の岩石に指定されました)

International Shipping Methods
Proxy bidding and purchasing services are becoming increasingly convenient. However, overseas shopping carries certain risks and issues. To reduce these risks and enhance shopping safety, please be sure to read the following information:

1. International Shipping

   Air Freight: If the item status is not confirmed within two days after the arrival notice, any customer complaints cannot be addressed with the seller.

2. After Receiving the Product

Please confirm and inspect the product as soon as possible to ensure that the product specifications, quantity, accessories, and description are correct

If, unfortunately, there are any issues, you can refer to the following examples on how to report related product problems:
1. Example of missing product information
2. Example of product not matching provided information
3. Example of damaged product information

Important Notes: 1. If the seller is unwilling to ship overseas or is unaware that the product will be shipped overseas, the international shipping cost for returns or exchanges will need to be borne by the member. You may refer to the EMS e-Express fee inquiry from the post office. If it involves alcoholic beverages or items that affect flight safety, the post office cannot be used for shipment, and only DHL can be used to ship back to Japan.
2. During the product complaint handling period, please retain the complete outer packaging of the product (including the shipping label information), and refrain from attempting any repairs or altering the original condition. Any modifications may result in the inability to process the case.

3. After Inspecting the Product

After receiving and inspecting the item, if you have any questions, it is recommended to contact Letao within 2 hours. Here are some reminders:

1. Please do not unpack, use or repair the received item yourself, and be sure to keep the original packaging to facilitate subsequent handling of related matters, so as to avoid changes to the item that may cause the seller to be unwilling to process.

2. You can call customer service, and the customer service will leave a message for you as below. Please provide the following information:
"Hello, we will first help you establish a complaint case for Product ID: _______ .But we need you to 2-3 clear photos of the product issue, including photos of the product problem, product packaging, shipping details slip, and outer box. Send them to service@letao.my and inform us of your desired resolution (failing to provide this may result in an inability to process subsequent matters). After sending the email, notify us in the customer service message. We will confirm with the seller as soon as possible. and if there are any related questions, we will contact you through the customer service message. Thank you for your cooperation."

Please provide:
1. "Product ID"
2. Photo of the "Delivery Note" (if any)
3. Photos of the outer box (including inner and outer packaging)
4. Photos of the product (Please include relevant descriptions to help us confirm with the seller)

Important Notes:
1. Do not include foreign text or other products in the background of the image.
2. Please keep the complete product packaging (including the shipping label information), and refrain from repairing or altering the original condition on your own, as any changes may result in the case being unable to be processed.
3. Please provide the relevant information within 48 hours to avoid missing the golden hour for reflection and causing situations that cannot be handled.
4. Due to 99% of Japanese sellers being unwilling or unaware of shipping goods overseas, if a seller is willing to handle the issue, the goods must be sent back to Japan, and the international shipping costs incurred must be borne by the member. Letao will use postal EMS international express to send the goods back to Japan.
5. As the goods are purchased from overseas, it may take approximately one to two weeks to complete the relevant processing procedures when issues arise with the goods. Please be reminded that you can inquire about the approximate cost through the EMS service at the post office.

4. FAQ

1. Issue of Authenticity: If antique or branded goods are found to be counterfeit upon receipt, clear photos showing the differences between the genuine product and the imitation must be provided as evidence. If unable to provide relevant proof, assistance can be sought to find a third-party reputable organization for a premium authentication service .
2. Leaking Iron Teapot: If an antique iron teapot is leaking, please take clear photos of the leaking area and provide them.
3. Transport Damage: If the goods are damaged during international shipping (to the pickup point), you need to provide photos of the outer packaging of the parcel and clear photos of the damaged goods' outer packaging.
