We take on a small number of custom projects each season, in an effort to give each client a deeply creative and rewarding experience. These projects take significant energy and time investment from both parties, so we ask that inquiries be made with serious intent, budget, and enthusiasm. A custom fee applies to all projects outside of M. Hisae's current body of work. All custom work is final sale. Direct inquiries to custom@mhisae.com.


Email custom@mhisae.com. Share your story, occasion, vision, materials, inspiration pieces, timeline, and budget. The more you provide, the better. Share photos of the loved one you're dreaming up this piece for.

Heirloom Stones
If you'd like to work with a family/heirloom diamond or gemstone as your center stone, share specs, measurements, and and appraisal report, if available. A setting fee applies. We do not work with melee or small diamonds. A liability waiver with your tailored information will be created and must be signed before the stone leaves your possession. The customer assumes all risks associated with repurposing stone(s), since fragility is inherent to organic material's age, current use, and history of use. The stone(s) will be inspected thoroughly upon arrival at the M. Hisae studio, and any additional points of concern will be noted in writing and shared with the customer. All custom work made with heirloom stones is final sale.


The Design Fee varies, depending on the project. The Design Fee is in addition to the cost of the finished piece, and is paid up front. It covers time spent designing, sourcing, pricing and laying specs for your piece(s). All designs are insured with our expertise, whether you have your own clear picture of the design or if we take the reins fully.

Once we've narrowed in on a basic vision and a range for your budget, we can hop on a call. Great ideas can come out of these phone calls. We collect all pertinent information to begin designing. Please allow 2-3 weeks for us to develop and sketch out your unique designs.

We will send you multi-angle renderings and full specifications for 1-3 finished pieces. Then, you pick your favorite. We will list turnaround times for each design. Typically, it's 5-6 weeks to receive the finished product from that point.

The entire process, from inquiry to finished piece, takes about 6-8 weeks. Please factor this time into your inquiry. We can often accommodate rush timelines, though a rush fee may apply.


We will source stone options (if applicable) for your piece and send detailed photos and videos. We can arrange for them to be mailed to you for in-person selection, if requested. Shipping fees apply if you would like to see gemstones in person.


Your finished piece is delivered or mailed in an appropriate gifting box. We love sharing projects with our community, so we'll speak about privacy requests.
