Selling a Diamond in San Diego: Quick Answer
If you want to sell a diamond in San Diego, bring the stone or piece to our Carmel Valley showroom for a free, no-obligation evaluation. Here is what determines what you will be offered:
- Offers are based on wholesale and secondary-market value, not the retail price you originally paid or an insurance appraisal figure.
- The 4 Cs drive most of the value — carat weight, cut, color, and clarity, with cut quality having an outsized effect on how a stone actually looks.
- A GIA certificate helps but is not required. It removes uncertainty about grading, which usually means a stronger, faster offer.
- Loose stones and mounted stones are both accepted. Setting metal is valued separately from the stone itself.
- Evaluation is free and takes about 20–40 minutes, done in front of you, with same-day payment if you accept.
- You can also borrow against the diamond instead of selling it if you want to keep ownership.
How We Value Your Diamond
Every diamond is evaluated using the four factors jewelers call the “4 Cs”: carat (weight), cut (proportions and brilliance), color (how colorless the stone is), and clarity (visible inclusions). We specialize in larger diamonds, 1.0 carat and up, though we evaluate stones of any size, shape, and certification status.
Does My Diamond Need a GIA Certificate?
A GIA certificate isn’t required, but it’s extremely helpful for larger stones since it provides an independent, trusted grading. If your diamond isn’t certified, our specialists can still evaluate it in person. We’re among the market’s highest-paying buyers for large carat diamonds, colored diamonds, and diamonds of any shape, including round brilliant, princess, cushion, Asscher, radiant, emerald, oval, pear, marquise, and heart cuts.
Loose Diamonds vs. Diamonds in Jewelry
We buy both. A loose diamond is valued purely on the 4 Cs, while a diamond set in a ring, necklace, or other piece is valued for the stone plus the metal content and craftsmanship of the setting.
Not ready to sell? You can also use your diamond as collateral for a diamond loan and keep ownership.
Diamond Shape Guide
| Shape | Characteristics |
|---|---|
| Round Brilliant | The most popular and valuable shape, cut for maximum brilliance and fire. |
| Princess | Square shape with sharp corners, second most popular for engagement rings. |
| Cushion | Square or rectangular with rounded corners, popular in vintage-style settings. |
| Emerald | Rectangular step-cut, emphasizes clarity over brilliance. |
| Asscher | Square step-cut, similar to emerald with a vintage Art Deco appeal. |
| Oval | Elongated round shape that can appear larger per carat. |
| Pear | Teardrop shape combining round and marquise characteristics. |
| Marquise | Elongated shape with pointed ends, maximizes apparent size. |
| Radiant | Rectangular or square with trimmed corners and brilliant faceting. |
| Heart | Romantic symbolic shape, requires excellent symmetry to look its best. |
Diamond Clarity Chart
| Grade | Meaning |
|---|---|
| FL / IF | Flawless / Internally Flawless — no inclusions visible under 10x magnification. |
| VVS1 / VVS2 | Very, Very Slightly Included — inclusions extremely difficult to see under magnification. |
| VS1 / VS2 | Very Slightly Included — minor inclusions, difficult to see under magnification. |
| SI1 / SI2 | Slightly Included — inclusions visible under magnification, sometimes to the naked eye. |
| I1 / I2 / I3 | Included — inclusions visible to the naked eye, may affect durability or brilliance. |
Diamond Cut Grade Chart
| Grade | Effect on Appearance |
|---|---|
| Excellent | Maximum brilliance and fire, reflects nearly all light that enters. |
| Very Good | High brilliance, reflects most light, difficult to distinguish from Excellent to the naked eye. |
| Good | Reflects a majority of light, solid value for the price. |
| Fair | Noticeably less brilliant, light escapes through the sides or bottom. |
| Poor | Significant light loss, visibly less lively than well-cut stones. |
Diamond Color Chart
| Grade Range | Description |
|---|---|
| D – F | Colorless, the most valuable and rarest color range. |
| G – J | Near colorless, color is difficult to detect face-up. |
| K – M | Faint yellow or brown, noticeable to a trained eye. |
| N – Z | Light to noticeable color, significantly more affordable. |
| Fancy Colors | Vivid colored diamonds (pink, blue, yellow, and others) are graded on a separate scale and can command significant premiums over colorless stones. |
Types of Diamonds We Buy
We evaluate and buy every category of diamond, including:
- Loose diamonds — certified or uncertified, any shape or size.
- GIA and IGI certified diamonds — we recognize both major grading labs; GIA is generally considered the strictest and most conservative standard, which we factor into our evaluation.
- Engagement rings and diamond earrings — valued for the stone plus the metal and craftsmanship of the setting.
- Diamond tennis bracelets — valued based on total carat weight across all stones plus the setting.
- Estate and inherited diamonds — including pieces without paperwork or of unknown origin, evaluated the same day.
- Colored and fancy diamonds — including fancy yellow, pink, and other vivid colors, which we evaluate as investment-grade pieces when appropriate.
Understanding Wholesale, Retail, and Resale Value
One of the most common points of confusion when selling a diamond is why an offer differs from what you originally paid or what you’d see at a retail jeweler. There are several distinct values at play:
- Retail value — what a jewelry store charges a consumer, including markup, overhead, and profit margin.
- Wholesale value — what dealers pay each other for stones, without retail markup.
- Resale/secondary market value — what a diamond commands when sold second-hand, which is typically below original retail price since the retail markup isn’t recoverable.
- Insurance replacement value — the cost to replace an item with a similar new one at retail, used for insurance purposes and typically the highest of all these figures.
When we make you an offer, we’re pricing based on wholesale and resale market value, since that reflects what we can realistically recover, not the retail or insurance replacement price. Understanding this distinction helps set realistic expectations before you come in.

Frequently Asked Questions
Do I need a GIA certificate to sell my diamond?
No, though it’s very helpful for larger stones since it provides independent verification of the diamond’s exact grade. We can still evaluate uncertified diamonds in person.
What size diamonds do you buy?
We specialize in diamonds 1.0 carat and up, but we evaluate and buy diamonds of any size.
Do you buy colored diamonds?
Yes, we’re among the market’s highest-paying buyers for fancy colored diamonds in addition to traditional colorless stones.
Can I sell a diamond that's still set in a ring?
Yes, we evaluate the diamond and the setting together, or you can have the stone removed first if you prefer.
How is the price determined?
We assess carat weight, cut, color, and clarity, then price according to current market conditions for stones of that grade.
Can I get a loan against my diamond instead of selling it?
Yes, diamonds can be used as collateral for a cash loan if you’d rather keep ownership.
Do you buy diamonds without any paperwork at all?
Yes, paperwork isn’t required for us to evaluate and buy your diamond, though it can support a stronger offer.
What's the difference between GIA and IGI certification?
GIA (Gemological Institute of America) is widely considered the strictest, most conservative grading standard in the industry. IGI is also respected but tends to grade slightly more generously. We factor the certifying lab into our evaluation.
Do you buy diamond tennis bracelets?
Yes, we evaluate tennis bracelets based on total carat weight across all stones, individual stone quality, and the metal setting.
What are fancy colored diamonds worth compared to colorless diamonds?
Vivid fancy colors like pink, blue, and certain yellows are graded on a separate scale and can command significant premiums over colorless stones of similar size, depending on color intensity and rarity.
Why is my offer lower than what I paid at retail?
Retail prices include markup, overhead, and profit margin that isn’t recoverable on the secondary market. We price based on wholesale and resale market value, which is typically below original retail price.
Do you buy diamond earrings?
Yes, we evaluate diamond stud and drop earrings the same way we evaluate any diamond jewelry, based on the 4 Cs of each stone plus the setting.
What is diamond fluorescence?
Fluorescence is how a diamond glows under ultraviolet light. Depending on intensity and the diamond’s color grade, it can slightly increase or decrease value.
Can I sell a diamond with no paperwork or certification?
Yes, uncertified diamonds are evaluated in person by our specialists using the same 4 Cs criteria.
Do you buy diamonds from estate sales or inheritance?
Yes, we regularly evaluate and buy inherited and estate diamonds, including pieces with unknown history or provenance.
