Custom Cutting A Diamond
So you’ve found the type diamond you want with regards to cutting style but you’ve also come to learn that the clarity range, color range and size range of what you’re looking for is not available. Or perhaps it’s an unusual and rare combination of carat, clarity & color and *THAT’S* what you want!
That makes you a perfect candidate to consider having a diamond custom cut to your liking.
Before you decide to embark down this path there are some things you need to be aware of.
- Depending on the type of cut it …
- Can perhaps be cut from an existing diamond on the market already or
- Must be cut from the sourced rough material.
If it can be custom cut from an existing diamond on the market then we can pretty much guarantee you minimum specs it will result in. Say for example you are looking to purchase an Ascendancy Hearts & Arrows, an August Vintage European Cut or perhaps a Solasfera, Star129 or one in the list below. In these cases we can generally take a pre-existing diamond on the market and recut it to the desired cut. Since it will have already been graded by GIA or AGS we pretty much know what it will result in upon completion. Diamonds that can be custom cut from pre-existing diamonds on the market would be the following …
- Hearts & Arrows Rounds
- August Vintage European Cuts
- Solasfera Hearts & Arrows
- August Vintage Asscher
- Solasfera or Signature Princess Cut
- Ensure graining levels are not too high (Graining Video)
- Ensure there is little to no existing strain in the diamond. Strain can cause a diamond to bust on the wheel.
- Ensure that the re-cutting will not result in surface breaching inclusions on the crown thus compromising structural integrity.
- Ensure that the proportions and precision of the diamond's cut will not result in too much weight loss as to decrease the value of the gem upon the loss of weight. Decreasing weight to increase cut quality does balance value but there are many diamonds on the market which would result in the loss of too much weight. When we hand pick the diamond we only source those that will yield the best results for our clients.
- The acquisition process. As we will be transporting in multiple diamonds to analyze to cut for you there is going to be some up front expenses involved. The costs associated depends on the value of the diamond. As we will generally be inspecting up to 5-6 diamonds to consider for cutting we'll be transporting these here to the lab for inspection. Here is an example of what it costs to transport diamonds of various values.
- To begin the acquisition process, as well as demonstrate your equal commitment to the project we will require a non-refundable deposit to help us with the costs of transporting diamonds for inspection. While we will be inspecting multiple diamonds we only require your deposit to cover round trip shipping of 2. Your deposit however is not wasted as it will be applied to the final purchase.
- Once the diamonds are here in our lab we will run them through the necessary testing to vet and ensure they meet our qualifications of our QA for recutting. If none of the diamonds qualify we will proceed to acquire a 2nd batch of diamonds at our expense and continue to do so until we have found a suitable candidate.
- Once we do locate a suitable diamond we will need you to be prepared to wire the amount so we can procure the diamond for cutting. Payment needs to be made the same week as we can only secure diamonds off of the market for no longer than a week.
- Once payment is made we will proceed to ship the diamond to our cutters. Once there it takes approximately 2-3 weeks for the cutting process until they ship it back to us.
- Upon arrival we will inspect the diamond to ensure it has been cut to spec and once confirmed we then proceed to ship the diamond to GIA or AGS for final grading. Note: If you requested a GIA graded diamond the diamond will go back to GIA. If you requested an AGS graded diamond the diamond will go to AGS. We do not send the diamond to a different lab from whence it originated. And on a positive note if the diamond comes back as a higher grade than what we acquired it at you do not pay for the added value. :) It is also at this time when it is good to work with our settings specialists on the setting you would like to put the diamond in.
- Once the diamond arrives from GIA or AGS we then proceed to set the diamond in the setting you choose and ship the diamond to you fully insured overnight.

- Your desired carat weight range.
- Your desired clarity range.
- Your desired color range.
- Your budget for the diamond (preferred and ceiling).
- Any other gemological features you desire or not such as length to width ratio, fluorescence level, etc.
- Once the rough is located we will need you to be on standby to wire the funds to acquire the rough diamond for cutting.
- The cutting process takes about 2-3 weeks. After the diamond is completed it is sent to our labs for QA and analysis. It is at this time we can also forward you images and our testing on the diamond.
- We then forward the diamond to AGS for grading. This generally takes about two weeks.
- Once it arrives we publish the final details and lab Report and it is also at that time we can set your diamond if you have been working with your setting specialists during the wait.
- We then ship to you overnight and fully insured!
FAQ’s on Custom CuttingQ: How long does the process take?
A: It really depends on how long it takes to find the raw material to cut your diamond from. If we find it within a week we can realistically have it cut and all done within a month but on average let’s just say 6 weeks to 3 months to play safe.
Q: What guarantees do I have?
A: What you are guaranteed are the estimates we give you once the primary diamond is located and we will also guarantee you the quality of the cut. If we are cutting from rough we’ll forward you the estimates from the cutter and you can make your decision at that time. One example of a recent custom cutting we did for a client the estimates from our cutter/buyer came in as follows...
Polished weight estimation: 2.34 to 2.23ct+/-,
Color: 10% G / 20% H / 50% I / 20% J.
Clarity: VS++ (I can’t visualize any inclusions in its natural rough state), but as you notice in the image, it’s a bit frosty.
Positives: Blue fluorescence which has the potential for a whiter outcome.
Clarity looks loupe clean in its rough state.
The diamond itself finished as a 2.30ct I VS2.
Q: How many have come out to less than what you predicted?
A: To date none.
Q: Can I read about an experience a client of yours had with custom cutting?
A: Sure. Here are a couple of links.
A: Of course if we already possess what you want there is no need to custom cut you a diamond but in answer ... nope. You will not pay more than what we would charge as if we had stocked the item for inventory.
Q: If I have a diamond will you recut it to one of your proprietary cuts?
A: Yes as long as your diamond will lend itself to cutting what it is you want. Picking a rough or finished diamond for cutting involves quite a bit of gemological knowledge about the host diamond. There are factors that can cause a diamond to "bust" on while it's being cut if there are high levels of grain and strain in the raw material that the average layman can't discern for the cutting process. We have all the necessary tools in our lab to determine which are and aren't suitable for recutting. The cost to cut a diamond to the level of precision we feature in our proprietary cuts costs $800 per carat and in some cases an additional royalty fee..
Q: Can I purchase a diamond from a competitor and have it custom cut to one of your proprietary cuts?
A: No. While diamonds are the hardest substance known to mankind they will undergo more heat and pressure during the cutting process than at anytime in their existence (short of it being formed in the earth). Diamonds inherently have internal gemological characteristics like grain and strain which can cause a diamond to literally bust on the cutting wheel. We know from experience. :-/ When we are selecting an existing diamond on the market to custom cut we call in a variety of diamonds to check them, not only for internal gemological characteristics but to ensure that the proportion set will recut to the proper dimensions of the finished diamond, that inclusions will not cause structural integrity issues AFTER the recutting process, transparency issues due to either graining or fluorescence and of course that the finished diamond will hold a value equivalent to the current market price. If you randomly pick a diamond and all of the gemological features are fine but the diamond finished as a 1.3xct when you were wanting a 1.5xct diamond it is impossible for you to determine this without the proper gemological education and the tens of thousands of dollars in lab equipment that we possess in order to make these determinations.
Q: Will my custom cut diamond have Good Old Gold's Lifetime Polices?
A: Custom cut diamonds are not automatically covered under our Lifetime Policies. Lifetime polices are given at Good Old Gold discretion.
