Question 1

What is the difference between marble, granite, and quartzite?

Accepted Answer

Marble is a metamorphic rock formed from limestone, prized for its elegant veining and soft, luminous appearance. It is softer (Mohs 3-5) and requires sealing. Granite is an igneous rock — extremely hard (Mohs 6-7), durable, and heat-resistant, making it ideal for high-traffic kitchens. Quartzite is a metamorphic rock formed from sandstone under extreme heat and pressure. It combines the beauty of marble with the durability of granite, offering stunning veining with superior hardness (Mohs 7-8).

Question 2

What is engineered quartz and how does it differ from natural stone?

Accepted Answer

Engineered quartz (e.g., Caesarstone, Silestone, Cambria) is a man-made surface composed of roughly 90-94% ground natural quartz crystals bound with polymer resins and pigments. Unlike natural stone, it is non-porous, never needs sealing, and offers consistent color and pattern across slabs. However, it is not as heat-resistant as granite or quartzite and can discolor under prolonged UV exposure, making it less suitable for outdoor applications.

Question 3

What is porcelain slab and when should I choose it over natural stone?

Accepted Answer

Porcelain slabs are large-format engineered surfaces made from refined clay fired at extremely high temperatures. They are virtually non-porous, scratch-resistant, UV-stable, and available in designs that convincingly replicate marble, concrete, and wood. Choose porcelain when you want a low-maintenance surface for outdoor kitchens, commercial spaces, or areas where staining resistance is paramount.

Question 4

How do I choose between polished, honed, and leathered finishes?

Accepted Answer

Polished finishes produce a mirror-like shine that enhances color depth and veining — ideal for formal spaces and feature walls. Honed finishes create a smooth, matte surface that hides fingerprints and water spots better, making it popular for bathrooms and contemporary kitchens. Leathered finishes have a subtle texture with a soft sheen that resists fingerprints while adding tactile character.

Question 5

Are natural stone surfaces safe for food preparation?

Accepted Answer

Yes, when properly sealed, natural stone surfaces are safe for food preparation. Granite and quartzite are particularly well-suited due to their hardness and low porosity. Marble, while beautiful, is more porous and reactive to acidic foods, so it requires more careful use and regular sealing in kitchen applications.

Question 6

What does "book-matched" mean and why is it desirable?

Accepted Answer

Book-matching is a technique where consecutive slabs are opened like a book to create a mirror-image pattern. When installed side by side, the veining creates a dramatic, symmetrical butterfly effect. This technique is highly sought after for feature walls, bathroom surrounds, and kitchen islands.

Question 7

How much does natural stone typically cost?

Accepted Answer

Natural stone pricing varies significantly based on material rarity, origin, color, and veining. Common granites may start around $40-60 per square foot installed, while mid-range marbles and quartzites range from $70-120 per square foot. Premium materials like Calacatta marble and exotic quartzites can range from $150-500+ per square foot.

Question 8

What is the typical lead time from selection to installation?

Accepted Answer

For in-stock materials, the process from slab selection to installation typically takes 2-4 weeks. This includes template measurement, fabrication (7-10 business days), and installation. Custom orders or rare materials sourced from specific quarries may take 6-12 weeks.

Question 9

Can natural stone be used outdoors?

Accepted Answer

Yes, many natural stones perform beautifully outdoors. Granite, slate, limestone, and travertine are popular choices for patios, pool decks, and exterior cladding. Porcelain slabs are also excellent for outdoor use due to their near-zero water absorption and UV resistance.

Question 10

Where is your showroom located and what are your hours?

Accepted Answer

Our 12,000 sq ft showroom is located at 495 East Brokaw Road, Suite F, San Jose, CA 95112. We are open Monday through Friday from 8:30 AM to 5:30 PM, and Saturday from 10:00 AM to 4:00 PM. We are closed on Sundays.

Question 11

Do I need an appointment to visit the showroom?

Accepted Answer

Appointments are not required — walk-ins are always welcome. However, we highly recommend scheduling an appointment so that one of our stone specialists can give you dedicated, uninterrupted time. You can book an appointment online or by calling or texting us at (408) 441-1114.

Question 12

Can I see the actual slab I will receive before purchasing?

Accepted Answer

Absolutely. Unlike many retailers who sell from small samples, Bay Stone Depot allows you to see and select the exact slab that will be installed in your home. Our showroom displays hundreds of full-size slabs on our slab racks.

Question 13

Do you offer delivery throughout the Bay Area?

Accepted Answer

Yes, we deliver throughout the San Francisco Bay Area, including San Jose, Palo Alto, Mountain View, Sunnyvale, Cupertino, Los Gatos, Saratoga, Fremont, San Francisco, and surrounding communities.

Question 14

Do you work with contractors and designers?

Accepted Answer

Yes, we have a strong trade program for contractors, designers, architects, and fabricators. Trade professionals receive dedicated account management, competitive pricing, priority scheduling, and access to our full slab inventory. Contact us to set up a trade account.

Question 15

How do I clean and maintain my natural stone surfaces?

Accepted Answer

For daily cleaning, use a soft cloth or sponge with warm water and a pH-neutral stone cleaner (avoid vinegar, lemon juice, or harsh chemicals). Wipe up spills promptly. For deeper cleaning, use a stone-specific cleaner from brands like StoneTech or Miracle Sealants.

Question 16

How often should I seal my stone countertops?

Accepted Answer

Dense stones like granite and quartzite may only need sealing every 2-3 years. More porous stones like marble, limestone, and travertine benefit from annual sealing. A simple water test can tell you if it is time to reseal: pour water on the surface — if it darkens within 5 minutes, the stone needs sealing.

Question 17

What should I do if my marble gets etched or stained?

Accepted Answer

Light etching can often be removed with marble polishing powder. For stains, apply a stone poultice that draws the stain out over 24-48 hours. For stubborn stains or widespread etching, we can recommend trusted stone restoration professionals in the Bay Area.

Question 18

Can I place hot pots directly on my stone countertops?

Accepted Answer

Granite and quartzite can generally handle brief contact with hot pots without damage. However, we always recommend using trivets or hot pads. Engineered quartz is the most sensitive to heat and can be permanently discolored by hot pots, so trivets are essential.

Question 19

How do I prevent chips and cracks in my stone surfaces?

Accepted Answer

Avoid dropping heavy objects on edges, use cutting boards rather than cutting directly on stone, and do not stand on unsupported countertop overhangs. If a chip does occur, save the piece — many chips can be repaired with color-matched epoxy by a professional fabricator.
