About MahengeSpinel.com

MahengeSpinel.com provides information relating to Mahenge spinel, including topics such as:

  • gemstone origin
  • mining history
  • gemmology
  • colour and fluorescence
  • treatment
  • quality and value
  • laboratory documentation
  • collecting
  • jewellery
  • currently available gemstones

The website may also allow visitors to enquire about specific gemstones, sourcing requests, trade purchases or jewellery-related requirements.

Unless expressly stated otherwise, information published on MahengeSpinel.com is provided for general educational and informational purposes.

Educational information

We aim to provide accurate, well-researched information and, where appropriate, refer to recognised laboratories, scientific publications, field reports and other authoritative sources.

Gemstone research continues to develop, however, and information may change as new evidence becomes available.

We therefore do not guarantee that every piece of information on the website will always be complete, current or free from error.

Nothing on MahengeSpinel.com should be treated as a substitute for examination of an individual gemstone by a suitably qualified independent gemmologist or laboratory where such examination is appropriate.

Gemstone descriptions

Every natural gemstone is individual.

Descriptions on MahengeSpinel.com may include information such as:

  • weight
  • dimensions
  • colour
  • shape
  • cut
  • transparency
  • origin
  • locality
  • treatment
  • fluorescence
  • laboratory reports
  • provenance

We aim only to publish information that we reasonably believe to be accurate.

Where information has not been independently established, it may be omitted or identified as a stated or reported characteristic rather than presented as confirmed fact.

Trade terminology and subjective descriptions such as vivid, neon, electric, fine or similar terms describe visual or commercial impressions and should not be interpreted as standardised laboratory grades unless expressly stated otherwise.

Gemstone colour and photographs

We make reasonable efforts to present gemstones accurately.

However, gemstone colour can appear different depending on:

  • lighting conditions
  • viewing angle
  • camera equipment
  • image processing
  • display calibration
  • screen brightness
  • surrounding colours

Photographs and videos should therefore be treated as representations rather than guarantees that a gemstone will appear exactly the same in every environment.

Where colour is particularly important to a purchase, we encourage customers to request additional photographs or video under different lighting conditions before proceeding.

Origin

Where a gemstone is described as being from Mahenge, Tanzania or another geographic origin, that description may be based on information supplied with the stone, provenance, laboratory documentation or other evidence available to us.

Geographic origin determination is a specialist area of gemmology and may involve interpretation of microscopic, chemical and spectroscopic evidence.

A dealer's statement of origin is not necessarily equivalent to an independent laboratory conclusion.

Where a recognised laboratory has issued an origin opinion, we aim to identify that laboratory clearly.

Treatment

Where treatment information is available, we aim to disclose it accurately.

Gemstone treatment can sometimes require specialist laboratory examination to identify.

Unless a treatment conclusion is supported by appropriate documentation or reliable examination, we do not guarantee that an individual gemstone is untreated merely because no treatment is immediately apparent.

Customers purchasing significant gemstones may wish to obtain independent laboratory testing before completing a transaction.

Laboratory reports

Some gemstones displayed on MahengeSpinel.com may be accompanied by reports from independent gemmological laboratories.

A laboratory report remains the work and opinion of the laboratory that issued it.

MahengeSpinel.com does not control the laboratory's testing procedures, conclusions or terminology and does not guarantee that another laboratory would necessarily reach an identical conclusion.

Where a report number or laboratory information is displayed, customers are encouraged to verify the report directly with the issuing laboratory where possible.

Current stock and availability

Gemstones displayed within the Current Stock section are subject to availability.

A stone may become:

  • reserved
  • sold
  • withdrawn
  • unavailable

without immediate notice.

Displaying a gemstone on the website does not guarantee that it remains available at the time an enquiry is received.

Availability should be confirmed before relying on a listing.

Prices

Where a price is displayed to consumers, it relates to the individual gemstone described on that listing and is intended to show the total price, including VAT where applicable and any other unavoidable mandatory charges that can reasonably be calculated in advance.

We will not add unavoidable mandatory fees later in the purchase process. If the nature of a product or service means that the total price cannot reasonably be calculated in advance, we will explain clearly and prominently how the price will be calculated.

Prices may change before a transaction is agreed.

Some stones may be displayed as Price on Request. In that case, the total price and any applicable taxes or mandatory charges will be confirmed before a transaction is agreed.

Optional or destination-dependent costs may be additional where they are not part of the displayed total price. These may include:

  • laboratory certification
  • jewellery manufacture
  • setting
  • resizing
  • optional or non-standard delivery
  • additional insurance
  • customs duties, import taxes or brokerage charges imposed in the destination country

Any such costs known to us will be disclosed before a transaction is completed. Where a charge cannot reasonably be calculated in advance, we will state that it may be payable and provide the available basis for calculating it.

Enquiries are not automatically orders

Submitting a contact form, sourcing request or gemstone enquiry does not create a binding purchase contract.

A transaction is only considered agreed when the material terms of the sale have been confirmed between the parties and any required payment or deposit arrangements have been accepted.

We reserve the right to decline an enquiry or transaction where appropriate.

Sourcing requests

MahengeSpinel.com may assist customers looking for a particular type of Mahenge spinel.

A sourcing request does not guarantee that a suitable gemstone can be found.

Gemstone availability depends on factors including:

  • colour
  • quality
  • carat weight
  • shape
  • budget
  • treatment requirements
  • laboratory requirements
  • market availability

Any stone sourced for a customer will be presented for consideration with the information available to us before a purchase is agreed.

Payment

Where a gemstone purchase or other transaction is agreed, payment arrangements will be confirmed separately.

Do not submit payment card details or banking information through the general website contact form.

Any payment instructions should be verified carefully before transferring funds.

Delivery and insurance

Where physical gemstones are supplied, shipping, delivery method and insurance arrangements will be agreed as part of the transaction.

Customers should ensure that the delivery information they provide is accurate.

International customers may be responsible for customs duties, import taxes, brokerage charges or other costs imposed within the destination country.

These costs are generally outside our control.

Returns and consumer rights

For eligible online and other distance purchases by UK consumers, you normally have the right to cancel without giving a reason by telling us within 14 days after the day on which you receive the goods.

After notifying us that you wish to cancel, you normally have a further 14 days to return the goods. Unless otherwise required by law, you may be responsible for the direct cost of returning them where this was disclosed before purchase.

Where the right to cancel applies, we will make the required refund within 14 days after receiving the returned goods or evidence that they have been sent back, whichever is earlier. The refund will include the cost of our least expensive standard delivery option. We may reduce the refund to reflect any loss in value caused by handling beyond what is necessary to establish the nature, characteristics and functioning of the goods.

The statutory cancellation right does not apply in every case. Exceptions may include goods made to a consumer's specifications or clearly personalised, although an item is not necessarily exempt merely because it was obtained or assembled following an order.

Different arrangements may apply to business-to-business purchases and will be confirmed as part of the individual transaction.

Nothing in these Terms & Conditions is intended to remove or restrict statutory rights that cannot lawfully be excluded.

Your rights where goods are faulty, not as described or otherwise fail to conform to the contract are not affected.

Value and investment

Gemstone prices can change significantly over time.

Statements about rarity, desirability, market conditions or historical prices should not be interpreted as a promise that a gemstone will increase in value.

MahengeSpinel.com does not provide regulated financial or investment advice.

You should not purchase a gemstone solely on the assumption that it will generate a financial return.

Jewellery and setting

Where information is provided about setting, jewellery design or gemstone care, it is general guidance only.

Individual gemstones and jewellery designs may require assessment by an experienced jeweller or setter.

MahengeSpinel.com is not responsible for damage resulting from work performed by an independent jeweller, setter, repairer or other third party unless responsibility has expressly been agreed as part of a separate service.
