Keep your future investment safe.

At Ashcroft & Oak Jewelers, we know what an important investment buying a diamond can be. That's why with every certified diamond purchase, we make sure you have three things: your Gem Certificate, our "We Will" Guarantee and your bill of sale - all tucked in their own folder and ready to keep with all your other important documents.

Your Gem Certificate

Your Gem Certificate gives you the exact weight, shape/cut, color, clarity and measurements of the diamond you have selected. The object of this card is to provide you sufficient support of your purchase, if necessary.

Below is a detailed description of your Diamond Certificate:

• A - Description: Detail of what the diamond is set into.
• B - Certificate Number: This uniquely identifies your diamond. The lab keeps an internal copy of everything that is on the certificate, plus some additional information for their files. If you call up the lab and give them the certificate number, they can reissue if you lost it.
• C - Shape and Cut: Shapes include round, pear, heart, marquise, etc. It also details the cutting style.
• D - Measurements: The dimensions of the diamond listed as minimum diameter to maximum diameter times depth for round shapes and length times width times depth for fancy shapes.
• E - Weight: One carat is equal to 1/5 of a gram. Weight is recorded to the nearest 1/100th of a carat.
• F - Color Grade: Assesses the absence of color from colorless to light yellow, brown or gray when compared to a master set of color comparison diamonds or when subjected to a colormeter.
• G - Clarity Grade: Represents the relative absense of inclusions (internal characteristics) and blemishes (external characteristics). Clarity is graded on a relative scale from flawless to included based on size, nature, position and quality of clarity characteristics visible under 10x magnification.
• H - Finish: Finish grades represent the quality of the surface condition (polish) and the size, shape and placement of the facets, including the evenness of the outline (symmetry). Grades are given as excellent, very good, good, fair and poor.
• I - Comments: Graded in the mounting.

Our "We Will Guarantee"*Ω

Our "We Will Guarantee" helps to keep your diamond at maximum value. We guaratee your diamond against loss from the mounting and from chipping & cracking forever provided you have it inspected by us, at no cost, every six months. Just keep up your six month inspection and we will also repair your jewelry mounting and prongs at no cost to you forever. Plus, we will accept your Ashcroft & Oak diamond that is at least 75% of your trade-in value. You must present your "We Will Guarantee" certificate at time of trade-in.

Keep your bill of sale to protect your investment in case of loss or theft.

If you have any questions or concerns about your investment, your sales associate is just a phone call away.

Our Policy On Conflict Diamonds:

Please be advised that we fully support a policy of not purchasing diamonds illicitly seized and sold by rebel forces. Since it is not currently possible for retail jewelers to verify the country of origin of diamonds, we work closely with our diamond suppliers to ensure that they do not knowingly purchase diamonds from conflict areas.

Accordingly, we ask them to commit that all diamonds sent to us have been purchased from legitimate sources not involoved in funding conflict and in compliance with United Nations Resolutions. They guarantee us that these diamonds are conflict free, based on personal knowledge and/or by written guarantees provided by the supplier of these diamonds.
