Choose PHI when…
PHI by Aurea Stone
- ·You need 3cm full-body depth — pattern through the entire slab thickness
- ·The edge detail will be visible (island waterfall, furniture legs)
- ·You want 12 color options with polished and honed finishes
- ·Mitering or lamination is not practical for your project
- ·Bookmatching is a priority (Palace, Paradise, Kepler, Koi)
Choose Symphony when…
Symphony by Aurea Stone
- ·You need 2cm slabs — wall cladding, vanities, lighter applications
- ·Your project requires EPD certification or LEED documentation
- ·Sustainability is a client specification — 90% recycled content
- ·Zero water waste manufacturing matters to your project
- ·You prefer matt finish options alongside polished

Technology
What makes each different
4R+ Fullbody — PHI only
4R+ Fullbody is the defining technology of PHI. The color and pattern are not just printed on the surface — they run through the entire 3cm slab thickness. When you cut PHI, the cross-section looks identical to the face.
This eliminates the need for mitering at edges, simplifies waterfall island fabrication, and means no visible color difference when the slab is cut to reveal an edge. It is the closest engineered stone comes to natural stone in terms of dimensional authenticity.
EcoPress — Symphony only
EcoPress is Symphony's manufacturing process — the lowest environmental impact production method in the engineered stone industry. It achieves zero process water waste (all water is captured and recycled) and up to 90% recycled raw material content.
Symphony also holds an EPD (Environmental Product Declaration) — an independently verified document that quantifies its environmental impact across the full lifecycle. Required for LEED documentation and increasingly specified by architects on green building projects.
Shared by both
NanoInk Technology
Ink injected up to 1mm deep into the surface — true 3D visual depth, high-definition sharpness, non-yellowing whites.
NEOS Protection
Permanently bonded surface protectant applied during manufacturing. Lifetime anti-stain warranty, food-safe, chemical-resistant.
0% Crystalline Silica
Independently certified at zero crystalline silica content. No OSHA silica dust controls required during fabrication.
Frequently Asked
PHI vs Symphony — common questions
Can I use Symphony for kitchen countertops?
Yes. Symphony performs identically to PHI on countertop surfaces — non-porous, stain-resistant, NEOS lifetime warranty. The main practical difference is that Symphony's pattern is printed on the surface and does not run through the full slab thickness. For standard countertop applications where the edge is simply eased or bullnosed, this is rarely visible. For waterfall edges or visible full-thickness cuts, PHI's 4R+ Fullbody technology is more appropriate.
Is PHI or Symphony more expensive?
Both are priced in the premium segment. Pricing varies by color, finish, and order volume. Contact Urban Stone Source at (336) 407-9167 or sales@urbanstonesource.net for current pricing on specific colors for your project.
Which one is better for an EPD specification?
Symphony. Symphony by Aurea Stone holds an EPD (Environmental Product Declaration) — an independently verified lifecycle environmental assessment required for LEED documentation and green building specifications. PHI does not hold an EPD certification.
Can I order samples of both PHI and Symphony?
Yes. Request samples at urbanstonesource.net/samples. Urban Stone Source ships PHI and Symphony samples directly to your showroom or project site in Georgia, Alabama, or Tennessee. No commitment required.
